The case for fish farming | Mike Velings

So I come from the tallest
people on the planet — the Dutch. It hasn’t always been this way. In fact, all across the globe,
people have been gaining height. In the last 150 years, in developed countries, on average, we have gotten
10 centimeters taller. And scientists have a lot
of theories about why this is, but almost all of them involve nutrition, namely the increase of dairy and meat. In the last 50 years, global meat consumption
has more than quadrupled, from 71 million tons to 310 million tons. Something similar has been going on
with milk and eggs. In every society where incomes have risen,
so has protein consumption. And we know that globally,
we are getting richer. And as the middle class is on the rise,
so is our global population, from 7 billion of us today
to 9.7 billion by 2050, which means that by 2050, we are going to need at least
70 percent more protein than what is available to humankind today. And the latest prediction of the UN
puts that population number, by the end of this century, at 11 billion, which means that we are going
to need a lot more protein. This challenge is staggering — so much so, that recently, a team at Anglia Ruskin
Global Sustainability Institute suggested that if we don’t change
our global policies and food production systems, our societies might actually collapse
in the next 30 years. Currently, our ocean serves
as the main source of animal protein. Over 2.6 billion people
depend on it every single day. At the same time, our global fisheries
are two-and-a-half times larger than what our oceans
can sustainably support, meaning that humans take
far more fish from the ocean than the oceans can naturally replace. WWF recently published a report
showing that just in the last 40 years, our global marine life
has been slashed in half. And another recent report suggests
that of our largest predatory species, such as swordfish and bluefin tuna, over 90 percent has disappeared
since the 1950s. And there are a lot of great, sustainable
fishing initiatives across the planet working towards better practices
and better-managed fisheries. But ultimately, all of these initiatives are working
towards keeping current catch constant. It’s unlikely, even with the best-managed fisheries, that we are going to be able to take
much more from the ocean than we do today. We have to stop plundering
our oceans the way we have. We need to alleviate the pressure on it. And we are at a point where if we push much harder
for more produce, we might face total collapse. Our current systems are not going to feed
a growing global population. So how do we fix this? What’s the world going to look like
in just 35 short years when there’s 2.7 billion more of us
sharing the same resources? We could all become vegan. Sounds like a great idea, but it’s not realistic and it’s impossibly hard
to mandate globally. People are eating animal protein
whether we like it or not. And suppose we fail to change our ways and continue on the current path, failing to meet demands. The World Health Organization
recently reported that 800 million people are suffering
from malnutrition and food shortage, which is due to that same
growing, global population and the declining access to resources
like water, energy and land. It takes very little imagination to picture a world of global unrest,
riots and further malnutrition. People are hungry, and we are running dangerously low
on natural resources. For so, so many reasons, we need to change our global
food production systems. We must do better and there is a solution. And that solution lies in aquaculture — the farming of fish, plants like seaweed,
shellfish and crustaceans. As the great ocean hero
Jacques Cousteau once said, “We must start using the ocean
as farmers instead of hunters. That’s what civilization is all about —
farming instead of hunting.” Fish is the last food that we hunt. And why is it that we keep
hearing phrases like, “Life’s too short for farmed fish,” or, “Wild-caught, of course!” over fish that we know
virtually nothing about? We don’t know what it ate
during its lifetime, and we don’t know what
pollution it encounters. And if it was a large predatory species, it might have gone through the coast
of Fukushima yesterday. We don’t know. Very few people realize the traceability in fisheries
never goes beyond the hunter that caught the wild animal. But let’s back up for a second and talk about why fish
is the best food choice. It’s healthy, it prevents heart disease, it provides key amino acids and key fatty acids like Omega-3s, which is very different from almost
any other type of meat. And aside from being healthy, it’s also a lot more exciting and diverse. Think about it — most animal farming
is pretty monotonous. Cow is cow, sheep is sheep, pig’s pig, and poultry — turkey, duck, chicken —
pretty much sums it up. And then there’s 500 species of fish
being farmed currently. not that Western supermarkets
reflect that on their shelves, but that’s beside that point. And you can farm fish
in a very healthy manner that’s good for us, good for the planet
and good for the fish. I know I sound fish-obsessed — (Laughter) Let me explain: My brilliant partner and wife,
Amy Novograntz, and I got involved in aquaculture a couple of years ago. We were inspired by Sylvia Earle, who won the TED Prize in 2009. We actually met on Mission Blue I
in the Galapagos. Amy was there as the TED Prize Director; me, an entrepreneur from the Netherlands
and concerned citizen, love to dive, passion for the oceans. Mission Blue truly changed our lives. We fell in love, got married and we came away really inspired, thinking we really want to do something
about ocean conservation — something that was meant to last, that could make a real difference and something that we could do together. Little did we expect that that would
lead us to fish farming. But a few months after
we got off the boat, we got to a meeting
at Conservation International, where the Director General of WorldFish
was talking about aquaculture, asking a room full of environmentalists
to stop turning from it, realize what was going on and to really get involved because aquaculture has the potential to be just what our oceans
and populations need. We were stunned when we heard the stats that we didn’t know more
about this industry already and excited about the chance
to help get it right. And to talk about stats — right now, the amount of fish
consumed globally, wild catch and farmed combined, is twice the tonnage
of the total amount of beef produced on planet earth last year. Every single fishing vessel combined, small and large, across the globe, together produce about 65 million tons
of wild-caught seafood for human consumption. Aquaculture this year, for the first time in history, actually produces more
than what we catch from the wild. But now this: Demand is going to go up. In the next 35 years, we are going to need an additional
85 million tons to meet demand, which is one-and-a-half times
as much, almost, as what we catch globally
out of our oceans. An enormous number. It’s safe to assume that that’s not
going to come from the ocean. It needs to come from farming. And talk about farming — for farming you need resources. As a human needs to eat
to grow and stay alive, so does an animal. A cow needs to eat
eight to nine pounds of feed and drink almost 8,000 liters of water to create just one pound of meat. Experts agree that it’s impossible to farm cows for every
inhabitant on this planet. We just don’t have enough feed or water. And we can’t keep cutting down
rain forests for it. And fresh water — planet earth
has a very limited supply. We need something more efficient to keep humankind alive on this planet. And now let’s compare
that with fish farming. You can farm one pound of fish
with just one pound of feed, and depending on species, even less. And why is that? Well, that’s because fish,
first of all, float. They don’t need to stand around all day
resisting gravity like we do. And most fish are cold-blooded — they don’t need to heat themselves. Fish chills. (Laughter) And it needs very little water, which is counterintuitive, but as we say, it swims in it but it hardly drinks it. Fish are the most resource-efficient
animal protein available to humankind, aside from insects. How much we’ve learned since. For example, on top of that
65 million tons that’s annually caught for human consumption, there’s an additional 30 million tons
caught for animal feed, mostly sardines and anchovies
for the aquaculture industry that’s turned into fish meal and fish oil. This is madness. Sixty-five percent of these fisheries,
globally, are badly managed. Some of the worst issues
of our time are connected to it. It’s destroying our oceans. The worst slavery issues
imaginable are connected to it. Recently, an article came out of Stanford saying that if 50 percent
of the world’s aquaculture industry would stop using fish meal, our oceans would be saved. Now think about that for a minute. Now, we know that the oceans
have far more problems — they have pollution,
there’s acidification, coral reef destruction and so on. But it underlines the impact
of our fisheries, and it underlines how
interconnected everything is. Fisheries, aquaculture, deforestation, climate change, food security and so on. In the search for alternatives, the industry, on a massive scale, has reverted to plant-based alternatives like soy, industrial chicken waste, blood meal from slaughterhouses and so on. And we understand where
these choices come from, but this is not the right approach. It’s not sustainable, it’s not healthy. Have you ever seen a chicken
at the bottom of the ocean? Of course not. If you feed salmon soy with nothing else, it literally explodes. Salmon is a carnivore, it has no way to digest soy. Now, fish farming is by far the best animal farming
available to humankind. But it’s had a really bad reputation. There’s been excessive use of chemicals, there’s been virus and disease
transfered to wild populations, ecosystem destruction and pollution, escaped fish breeding
with wild populations, altering the overall genetic pool, and then of course, as just mentioned, the unsustainable feed ingredients. How blessed were the days when we could just enjoy
food that was on our plate, whatever it was. Once you know, you know. You can’t go back. It’s not fun. We really need a transparent food
system that we can trust, that produces healthy food. But the good news is that decades of development and research have led to a lot of new
technologies and knowledge that allow us to do a lot better. We can now farm fish
without any of these issues. I think of agriculture
before the green revolution — we are at aquaculture
and the blue revolution. New technologies means that we can now produce a feed
that’s perfectly natural, with a minimal footprint that consists of microbes, insects,
seaweeds and micro-algae. Healthy for the people, healthy for the fish, healthy for the planet. Microbes, for example, can be a perfect alternative
for high-grade fish meal — at scale. Insects are the — well, first of all, the perfect recycling because they’re grown on food waste; but second, think of fly-fishing, and you know how logical
it actually is to use it as fish feed. You don’t need large tracts of land for it and you don’t need
to cut down rain forests for it. And microbes and insects are actually
net water producers. This revolution is starting as we speak, it just needs scale. We can now farm far more
species than ever before in controlled, natural conditions,
creating happy fish. I imagine, for example, a closed system that’s performing
more efficiently than insect farming, where you can produce
healthy, happy, delicious fish with little or no effluent, almost no energy and almost no water and a natural feed
with a minimal footprint. Or a system where you grow
up to 10 species next to each other — off of each other, mimicking nature. You need very little feed, very little footprint. I think of seaweed growing
off the effluent of fish, for example. There’s great technologies
popping up all over the globe. From alternatives to battle disease so we don’t need antibiotics
and chemicals anymore, to automated feeders that feel
when the fish are hungry, so we can save on feed
and create less pollution. Software systems that gather
data across farms, so we can improve farm practices. There’s really cool stuff
happening all over the globe. And make no mistake —
all of these things are possible at a cost that’s competitive
to what a farmer spends today. Tomorrow, there will be no excuse
for anyone to not do the right thing. So somebody needs to connect the dots and give these developments
a big kick in the butt. And that’s what we’ve been working on
the last couple of years, and that’s what we need
to be working on together — rethinking everything from the ground up, with a holistic view
across the value chain, connecting all these things
across the globe, alongside great entrepreneurs that are willing to share
a collective vision. Now is the time to create
change in this industry and to push it into
a sustainable direction. This industry is still young, much of its growth is still ahead. It’s a big task, but not
as far-fetched as you might think. It’s possible. So we need to take pressure off the ocean. We want to eat good and healthy. And if we eat an animal,
it needs to be one that had a happy and healthy life. We need to have a meal that we can trust, live long lives. And this is not just for people
in San Francisco or Northern Europe — this is for all of us. Even in the poorest countries, it’s not just about money. People prefer something fresh
and healthy that they can trust over something that comes from far away
that they know nothing about. We’re all the same. The day will come where people will realize — no, demand —
farmed fish on their plate that’s farmed well
and that’s farmed healthy — and refuse anything less. You can help speed this up. Ask questions when you order seafood. Where does my fish come from? Who raised it, and what did it eat? Information about where your fish
comes from and how it was produced needs to be much more readily available. And consumers need to put pressure
on the aquaculture industry to do the right thing. So every time you order, ask for detail and show that you really care
about what you eat and what’s been given to you. And eventually, they will listen. And all of us will benefit. Thank you. (Applause)

    I'm a wildlife biologist, so let me just explain a few things to the reactionaries here. Fish, but even better mollusks, are some of the most efficient sources of meat in terms of energy input/energy output. If done correctly, fish farming has very minimal impact compared to traditional trawl fishing or other mass catch methods. Yes we should reduce our meat intake, but that's unrealistic in the short term.

    However if uneducated people didn't freak out over every single industrial or large scale agriculture process then we'd be far better off.

  2. Carde Author

    I agree with most said in this talk, however as others noted one of the critical issues with meat and fish farming is antibiotics abuse. That problem will kill us far more swiftly than a tuna that spend a day or 2 in radioactive waters.

  3. Diana8Matienzo Author

    How is veganism not sustainable? I am not vegan or vegetarian, but rationally thinking, farming animals takes up more resources from humans and creates so much waste! It is possible to focus on eating plant-based foods and creating food that have a full amino acid complex and high protein content without going the farming route. Animal abuse in farming is a whole other issue. I am a powerlifter and understand completely the want for protein, but this is not the solution.

  4. jbiasutti Author

    The problem is feeding the fish, you either need to take land based protein to feed the fish, or take sea based protein to feed the fish.

  5. MrVlonk Author

    Please do not judge this man who is doing good work to reform an industry towards sustainability and a better future!
    How radical is your worldview if even this man gets a downvote? He comes to speak about mistakes in mass animal farming! He is already a half step towards your worldview. I shall not condemn the eating habits of others…

  6. Sam Johnston Author

    I hate to think of the world's oceans being irreversibly destroyed due to ignorance and lack of public knowledge. I'm torn between keeping my vegetarian choices private and shouting about it to enlighten anyone who may be unaware but willing to make a change if they were equipped with the right information 😭

  7. vella mour Author

    I think this is a good short term solution. A baby-step goal in the process to a different way to get sustainable (plant-based) food.

    If I let you eat fish, will you stop eating cows, pigs, chickens, turkeys, lambs, etc?

  8. Lloyd Author

    I'd happily eat only plant. I prefer a lovely spicy bean burger to a beef burger any day. The problem comes in forcing 7 billion + people to not eat meat. Do you really expect to unify the world on this issue? There are FAR more outrageous ethics still thriving in many parts of the world.

    I care about sustainable fishing. Some of the fishing practices today are truly disgusting. It's quite comparable to de-forestation of the earth. Would you ban the world from using wood? No – you make sure you are harvesting trees in a sustainable way.

  9. resignator Author

    Want to make a real impact on the world? Dont have kids. Overpopulation is the planet's largest threat not my love of an occasional grilled fish. I did my part when I got a vasectomy. That's more than 99% of vegans will ever sacrifice. Good luck trying to convince humans they arent omnivores though. Abstinence, as the puritans taught us, is the best way to defy nature.

  10. bangletigress Author

    This is better than overfishing but plant based diets would be a more effective solution. Flax or hemp seed also has omega threes.

  11. Megan B Author

    If we stopped farming on land, there would be more space for further population growth. This population would need food too, leading to greater demands of fish from these fisheries.
    In the long term then, we'd end up where we are now with the land situation. There wouldn't be enough ocean left to fish without destroying habitats and space for the non farmed marine life. Therefore this case surely isn't sustainable.

  12. sellery1803 Author

    He should be pitching this to investors, expand this technology enough and you can effectively run fishing companies out of business without government intervention.

  13. Curtis Hanna Author

    "We could all become vegan. Sounds like a great idea but not realistic. and its impossible to mandate globalay. People are eating animal protein whether we like it or not"
    This line bothered me. Its called the invisible hand of capitalism. People wont eat as much animal protein and move onto plant based protein when meat becomes more expensive. Which it will. Meat becoming so extensive people eat it less is far more likely then his prediction of a near collapse of social order in the next 35 years.

  14. Doodelay Explains Author

    The guy misses the point. Stop hunting animals and stop farming them. Eat lab grown meat once it reaches a higher quality of taste than animal meat. Til then, eat everything else but animals

  15. Tom Seppe Author

    Why don't we try to consume more of what we make, instead of throwing away most of what we make. We could easily feed more people, if we stopped throwing food away

  16. djayjp Author

    Go vegan and stop torturing sentient life (all while saving human lives):

  17. scruffthemagicdragon Author

    Yet again they carefully, studiously avoid thinking about the one and only thing that can ever lead to sustainability: human population decline. Every solution Velings has will only lead to increased human population which in turn will lead to greater environmental problems. You cannot solve a population overshoot problem by supporting the population which wants to overshoot. You can only solve that problem by starving that overshot population. God this willful ignorance is depressing.

  18. MrSpeedDemon72 Author

    "Millions of people are suffering from food shortage", yet 10's of millions of more people are getting disease and dying from GMO food, farm raised fish feed GMO food. NEVER eat farmed raised anything!! This speaker sounds like someone from Monsanto.

  19. Gary Davies Author

    Plant-based food all the way. Time to leave animals alone. And within the first 90 seconds this dude's still pushing the Protein Myth. Wake up everybody – Vegan for a MUCH better future on Planet Earth

  20. Gabul4 Author

    1. There are already fish farms
    2. "Eating fish is healthy" is not an argument. You need a varied diet to be healthy.
    3. Comparing hunting of land-based animals to fishing is retarded for a multitude of reasons
    4. Our diet isn't the problem. Overpopulation is the problem. What we need to do, is to stop breeding like rabbits, not turn the entire oceans into farms.

  21. Jeandré du Toit Author

    "People are eating animal protein whether we like it or not" – Mike Velings.


    "No excuse for anyone to not do the right thing." – Mike Velings.

    If slavery can be outlawed, then we can "do the right thing" and outlaw both factory farming and fishing which creates orders of magnitude, of orders of magnitude more pain and suffering than all other slavery, torture, and killing, ever committed, combined.

    If slavery can be outlawed, then so can human overpopulating which is the root cause of the anthropocene mass extinction event, habitat destruction and degradation, anthropogenic climate change, factory farming, and industrial fishing.

    The idea that animal protein is healthy for humans contradicts all dietary scientific meta studies I've read.

  22. Cat Nip Author

    This is so stupid just go vegan and to the people who say you can't get all the vital nutrients you need Bullshit I myself am a vegan & very active Most of my intake is a vegan diet my grandmother is 96 she has lived most of her life as a vegan she is also very active she walks every morning she is still very sharp mentally & is living proof that a vegan diet works you guys don't want to give up on your colon festuring meat that's fine but don't make false claims about the benefits of being a vegan.

  23. AnimeShinigami13 Author

    By the way if anyone reading this wants to try it, there's a company in the pacific northwest that will sell you an aquaculture kit, all you need is 3 55 gallon drums, the proper filters and supplies, and a warm location such as a small backyard greenhouse.

  24. John Kesich Author

    And maybe we need to cut down on population growth?

    But no. As Alan Weisman points out in Countdown, Iran significantly cut its birth rate – not through draconian laws, but by clerics preaching that it was the responsible thing to do and pointing out the benefits. Note that this can only work in a society that has a social safety net. At any rate, thanks to US/Israeli bullying, the clerics changed their minds and started calling for more children – future soldiers to defend the country.

    Every other problem is exacerbated by overpopulation – when will we start dealing with it rationally?

  25. Al Muatasim Al-Siyabi Author

    Nature is always generously provides food for human consumption, we can as humans collaborate with the earth to sustain many food resources and contribute to a better life for us.

  26. Millena Ch Author

    We could see fishless oceans by 2048.For every 1 pound of fish caught, up to 5 pounds of unintended marine species are caught and discarded as by-kill.   As many as 40% (63 billion pounds) of fish caught globally every year are discarded.Scientists estimate as many as 650,000 whales, dolphins and seals are killed every year by fishing vessels.Fish catch peaks at 85 million tons.40-50 million sharks killed in fishing lines and nets.GO VEGAN IF YOU WANT TO SOLVE THE PROBLEM!!!

  27. Lorenzo Belfiore Author

    This is so f*ckin true and real, I suggest you all guys interested in the topic and wondering why Greenpeace etc.. are not addressing the issue, watch Cowspiracy : the sustainable secret

  28. dlovegrove11 Author

    This is revolutionary, I hope people start to see that this is the answer to our fishing problems before we completely destroy the oceans. Resources aren't unlimited, sustainability is going to be a huge part of daily life in the future.

  29. felixthecrazy Author

    Can you imagine a world where 100% of people went vegan. What happens to those millions upon millions of cows/pigs/chickens/etc? Do they all get euthanized? Or do they get feed until they die naturally? Millions upon millions upon millions of pounds of plants to feed animals for years only for all of it to be thrown away to rot when they die. And then if you do let them live, do you let them procreate? And where does all the money come from to feed and maintain them with no profit motive?

  30. groMMit1981 Author

    Why plan for 11billion population rather then work to say 8billion then reduce slowly over decades to 4billion THEN when the moon and mars and beyond are valid habitats let the breeders let loose.

  31. Blake Allen Author

    Because of fish farming and the suffering of innocent animals, I seriously feel like I have mild depression. Feeling like I have no power to change anything is incredibly awful and I have no idea why someone in the right mind would ever want to put animals through any process similar to the one millions of fish go through. Just because overpopulation is becoming a great issue doesn't mean the only solution it to torture animals who feel and suffer the same way we do in order to produce food.I wish the person in this video went more into detail about the horrors of fish farming because it can totally change your mind about it. If you can make a difference (not trying to be all cliche), seriously look into the everyday life of a fish in a fish farm and step up because I know I can't live with myself knowing what is happening around the world.

  32. domitry jobby Author

    very interesting video, i want to open a fish farm in the next year or two, i need to save same money but i think the business opportunity is great.

  33. Jack DeMarco Author

    where gonna start making the goop from the matrix to support life on earth, synthesised aminos, vitamins and nutrients to cope with the stress of food production unless we do somthing as a whole

  34. TableSalt17 Author

    The man address the issue fairly well. While all the vegans and vegetarians are correct, as he said, its not feasible to make everyone change their diet. Look how hostile people are to vegan/vegetarians. I'm for reduced meat consumption and increasing plant based diets, but this is a realistic step in the right direction.

  35. Even Andy Author

    For the people in the comments that say that we should ONLY be eating plant based matter, ergo problem solved. It's not that simple. A lot of crop agriculture has a particularly detrimental impact on the environment also.

    Soy is a good example of this, as a meat substitute, its crops consume vast tracks of land. This land unfortunately tends to be predominantly equatorial regions in which bio-diverse rainforest is made way for this mono species agriculture, which unfortunately is killing millions of other animal and plant species that depend upon these regions. It's true though that a lot of soy is used in animal farming too, and that on land animal agriculture is also particularly harmful to the environment, but plant farming causes issues also.

    That is why it is important to, yes cut down on meat, but also find good alternatives to the food sources we already have without becoming too reliant on one crop. Fish farming might be a solution.

  36. ChrisBSX Author

    I find many of the vegan and vegitarian commenters on videos like this to be deeply disturbing. These are people who are only willing to see one solution to a problem, their own, without ever considering that it might not be a one size fits all issue. Add to this the fact that they are chasing people away from their ideology by being downright hostile. These are people who seem disinterested in actaully finding solutions and more determined to yell from a soap box, sad for the movement, sad for all the potential vegitarians/vegans they are alienating.

  37. Simon Milton-Jones Author

    It's a fascinating idea. I live at the head of a fjord in Norway and am interested in knowing more about how to develop a friendly, sustainable fish farm.

  38. John Doe Author

    His statement about fish helping fight heart disease is up in the air now. It turns out that the Inuit have a genetic mutation that shuts down most of their omega-3 and omega-6 polyunsaturated fatty acid production. It wasn't the diet high in fish with high levels of omega-3 fatty acids that lowered the incidence of heart disease despite the high fat diet.

  39. The Paper Pineapple Author

    Many of the worlds mangrove forests have been cleared to make way for shrimp farms. Seeing as how many of the ocean's fish only lay their eggs in mangroves stands, these shrimp farms have had a huge impact on how many fish are out in the ocean. In fact, a boat trawling for wild shrimp depletes the ocean of fewer fish than farming shrimp does in a former mangrove forest. Shrimp farms are on the up and up though because they're much cheaper ,in terms of money, than trawling for shrimp in a boat. However, some pieces of land and areas of coastal water support less wildlife than others. As long as you put your fish farms somewhere much less critical than mangrove forests, things work out better.

    "we could all go Vegan. it sounds nice, but Let's face it; It's not going to happen". With out an explanation why. Going Vegan was the easiest change of lifestyle i ever did, and managing the resources would be many times easier than sustaining todays agriculture.

  41. Amici Nybråten Author

    Vegetarianism is boring and just makes you feel starved all the time in my experience. But the biggest issue is really how easily fresh food gets old, so it's expensive to buy and tedious to maintain a fridge packed with it.

    However, I applaud all the technological breakthroughs that are happening in agricultural technologies, and as a Norwegian I already eat a lot of fish in my daily life (actually, close to a 50% split between fish and meat sometimes) and would love to eat more if it was just cheap enough and enough variation. I think government is partially to blame for a neglect in policy (probably also why my experience with vegetarianism is so bad, that is: meals consisting entirely of non-meat/-fish). I'd also love to try eating insects, but only as long as they don't look like insects, I really don't want a grasshopper roast, just mash the parts of it that matters with a nice sauce or soup and tell me it's tasty and healthy and I'll try it.

    It's healthy if you create a healthy farming system. Its not about the farm , it's about the care you put to it. there are food shortage and people need to be feed. and creating healthy farm, will feed the people. ..

  43. thewwwdude Author

    As with all other feedlot "farming" practices, fish farming poses sober and unacceptable risks – and uniquely, a direct threat to their wild counterpart in the case of wild salmon.

    Disease transference, sea lice proliferation, toxic chemical accumulation (PCB's), excessive antibiotic and chemical application, are all documented threats to both wild salmon and to consumers. Even the fact that despite colorant additives, farmed salmon still literally pales in comparison to wild salmon due to vastly inferior diets. Farmed diets are built on the backs of other species of fish, resulting in nearly complete depletion in those areas (3 lb. other fish required to produce a lb. of salmon). Farming salmon does not add to the overall food supply – merely upgrades the product, at great cost to ocean species. Aquaculture as currently practiced is desperately unsustainable.

  44. Aaron Verran Author

    wow simply stating veganism isnt the practicable solution and adding because people like to eat flesh? people like to smoke as well, does that mean they should continue? also his health claims are without evidence, so they are to be dismissed without evidence.

  45. Scott Nemeth Author

    Limiting Procreation will also solve the problem too, in order to prevent overpopulation, starvation, and extinction of food sources. A bit harsh, but better then watching a child die of starvation. However, Fish farming in inline closed off smaller container with a constant current mixture of atmosphere to provide more oxygen to the water systems to help prevent stagnant water from creating bacteria blooms with the aid of in line filtration units and steam heating system to kill bacteria and virus from a contaminated container of fish…however, i don't think this is very cost effective. Plus the costs to run an international organization to insure the safety of the fish products from hatcheries around the world as well as inspections to insure that health code mandates and procedures are being followed which only means more added costs that the general public doesn't want to pay for with exceptions based on understanding or care for health over money. I'm just one nut that fell from the tree making an assumption based on 10 years working in the manufacturing business and a little bit of experience in dealing with state of the art filtration units (Granted it's more of a general understanding since I'm normally the one programming the automated work cells.) for keeping coolant clean of bacteria for cnc and milling machines in the auto industry on a global scale. Anyhow, I'm not stating any blame or right of wrong answers because I know it's a serious, difficult issue with no easy answer and mistakes will be made in trying to find humane solutions to life altering issues. Seriously, how does the old Thomas Edison quote go, "I have not failed. I've just found 10,000 ways that won't work." If we give up after every mishap, granted this mishap can wipe out an entire species, then we would never come up with a viable positive solution and humanity would never move forward, being stuck in making the same makes over and again without realizing our ignorance. In the end we need people to work together for solutions, instead of placing blame for mistakes because the blaming game just states the problem offers no solutions. I understanding the blame game for those who blatant disregard to the general population, health codes, and safety, but not for trying to help do the right thing. Will any solution be population free or problem free, highly unlikely, every solution still has it's flaws. It's like going to a dealership and demanding to buy a car that will work 100% of the time with zero maintenance cost for tires, brakes, ext. Fish Farming may come up with a viable solution or lead to a new engineered technology in the future. To flat out say that something is wrong or right is like telling an inventor that his idea will never work, is it a bad idea now, sure, but can it lead to a great idea, yes and people will doubt that inventor the entire time putting them down and labeling them as crazy until there invention flies, floats, sends a signal to outer-space and back to earth on the other side of the globe, or that launching a person to outer space and back in a reusable rocket is stupid and impossible. It our own greed that has created most of the problems and we have been gifted with great minds in each and every one of us to find trouble shoot problems and find a way to improve are life. We just need to try and put human greed aside which would also mean the general population would have to work together to fund such technologies….. NASA's has entire flight paths planned out for highways safety if we ever designed a viable flying car not to mention thousands of different patents for future thinking for technologically advancing society or designs that made commercial airlines more fuel efficient, faster, and quieter was all done with the aid of an organization that many people in the US don't think we need to fund anymore but more and more of there research is making its way into the private sectors and paving the way for better day to day technologies. Okay, I rambled a bit and got a little off track just opinions, not facts.

    If you eat animals it is very unlikely you will have a healthy long life! It is clear that your interest is to sell the idea that fish farming can be wonderful, it is your business after all!


    Not every situation is conducive to the free enterprise situation only. The ocean has all the minerals, and water it needs for life but it lacks habitat. So its production is relatively poor. Communist undertakings to put in habitat, in the form of artificial reefs, will create a lot more output.

    I would like to develop a kelp field in the area of Southern-California in federal waters. I would like to grow kelp from subsurface buoys to surface in areas where the water is too deep for kelp to grow from the seabed. One possibility is to make mooring lines for the subsurface buoys from recycled waste car tires. The tires would be cut and woven to lines using ring weave technology. I have hands on practical knowledge of ring weave technology. I have experience of boating in Southern-California waters. I have a way to collect and process tires, and to store relatively small amount of mooring lines on my property. I have the funds to obtain a boat for starting the process. I would need permission from federal authorities to place the lines and buoys at a convenient location. For this permit I would need more logistic data, of what kind of subsurface buoys and what kind of anchoring systems to use. Any cooperation would be appreciated to develop a plan of buoy and anchoring system definition. ([email protected]). Any cooperation would be appreciated to facilitate the permitting process.
