ornamental fish in aquaponics? | 5 points you should know

Can ornamental fish be used in aquaponics? This is what we’re going to see together in
this video. [Music] So in aquaponics, most of the time,
we grow food, we grow vegetables, and fish. Also bacteria but the aim of aquaponics is
very often to harvest some vegetables to be able to consume them, to feed your family with
something that is tasty and healthy but also to grow some fish, right? And in the fish, we can grow some fish because
you want to eat them or because you like to see them or both. Some people are vegans or vegetarians so they
don’t consume the fish and it’s very respectable, very good actually to just use the fish as
a part of the ecosystem but you don’t consume them. You keep them in the system, keep them in
the loop. You enjoy watching them. It’s like having an ornamental pond outside
but the whole aim is to have something that looks nice and at the end to harvest the plants,
the vegetables. So you can definitely do that and then in
terms of fish, you can either grow some fish such as I don’t know, tilapia and silver perch
in Australia, trout, whatever. You can grow them and not harvest them. You can keep them growing you know. As they are pets, they become your pet you
know. Or you can also grow some fish that are called
ornamental, or which means that they have some really nice color and that’s the type
of fish that you can generally see in aquariums or just ponds outside. So in terms of fish we have a big variety
of fish. If you have been — if you are living in a
tropical country, you can grow most of the fish that you can see in aquariums in aquaponics. If you are in a cold country, then you would
probably grow goldfish, that are ornamental fish, look amazing, very hardy, able to grow
in aquaponics. Or you can grow some koi as well, koi carps. You know, they are such type of fish that
can grow quite big and be very, very nice with very nice patterns and very nice colors. So that’s what I can recommend you but be
very careful where you live. You may have some specific regulations. For example, here in Australia in Melbourne,
we are not allowed to grow koi carps because carp is a fish that can grow very fast and
if you release into the environment it can just reproduce itself and just take the place,
take the bio type of other fish. So in this case, it’s considered as a pest
in Australia and that’s why we are not allowed to have it at home, to keep this type of fish
alive. So obviously, in this case, we can grow the
type of fish such as goldfish. So there are different options and I really
encourage you to do some research and see what type of ornamental fish you can grow
wherever you live. But if you live in a tropical country where
the temperature of the water is always above 23-24 degrees Celsius, most of the fish that
can be grown in an aquarium can be grown in this temperature; generally 25-27 degrees
is good. So yeah in this case, you have a very wide panel
of fish that you can use in aquaponics and that’s going to be great. There is one thing that you need to be very
careful. It’s the way you feed them. So you know if you grow some fish in aquariums,
you’re going to give them some fish food that is adapted to aquarium fish and in this fish
food very often there are some colorants to enhance the color of the fish. There are also some other chemicals, possible
chemicals that could be kind of good for the fish but not good for you if you consume the
fish in the long term. Even if you don’t consume the fish, putting in
some aquarium fish food in the tank, at the end in the long term, it’s going to finish
in the plants and you’re going to consume the plants. So I don’t recommend if you grow aquarium
fish, I don’t recommend to use aquarium fish food. I would recommend to use aquaculture fish
food. So you just need to find a fish food that
is adapted to the size of the fish and obviously, if you have a fish that is carnivorous, give
them some fish food that is adapted for trout. For example, if you have a fish that is more
vegetarian, try to adapt the fish food to the type of alimentation that your fish require
but try to stay away from aquarium fish food because as I said there may be some things
inside this fish food that you don’t want to find in your aquaponics system at the end. Also if your fish falls sick, don’t use some
chemicals that they sell in the aquarium store. Once you start to grow some food in the system,
you need to make sure you know exactly what you are putting in the system. So don’t put anything against algae. Don’t put any chemicals to try to remove the
parasites because those chemicals even if they kill the parasites and they keep the
fish safe, they’re going to finish in your system and therefore, they may kill your bacteria
or they may accumulate into the vegetables and you’re going to consume them. So that’s not what you want, right? You grow some food at home because you want
to grow some sustainable food. So you want it sustainable. You want to be healthy as well. So don’t put any chemicals in the system. So if you keep ornamental fish, don’t use
the medicines, the chemicals, or the fish food that is supplied with the fish when you
buy them. Just get something that is developed for aquaculture
and in this case, it’s going to be much better for your aquaponics system. If you want to know more about aquaponics,
you can get the free aquaponics training to build your own aquaponics system in the description
of the video just below. It’s a free step-by-step training to help
you to build but also to manage your aquaponics system in the best way possible. In this training,
you have access to six steps, which are going to give you the limits of aquaponics, the
ratio to respect, some very technical information that you really need to understand before
putting your aquaponics system together. So I hope you’re going to use it. It’s completely free so it would be a shame
to design an aquaponics system without using this free training. If you are new to the channel, you can subscribe. It’s a channel where I release one video every
week. And if you enjoyed the video, please give
it a like. If you are already growing some ornamental
fish, please put a comment in the video. Let us know what you are growing and if you
have any comments on the video, please share. It’s very interesting to see the point of
view of everyone. That’s how we all learn from each other. I’ll see you in the next video. Bye-bye. Don’t forget to get your free gift from this screen. You can also leave me a comment below the
video. Subscribe to the channel and see my last video. I really hope to see you soon and I wish you
a fantastic success with aquaponics. Have a good crop!

    Same in Western Australia in regards to carp. Silver perch are tolerated but like rainbow trout you need a translocation permit from fisheries department more for Rainbow trout, than silver perch. Silver perch tolerate the heat over here better than Trout a week of 25°C at night time will see fatalities. But in large enough system will get through

    I am just starting out in aquaculture and live inland NSW where we have temperatures down to minus 8 degrees and up to the high 30 degrees in summer . I bought Jade perch 6 weeks ago and within 3 days they died because of the cold. I now have some small trout who are fine at the moment but the water has reached mid 20 degrees a couple of times and summer is just beginning!! If I have goldfish can I feed them with trout pellets. Any advice would be appreciated. Thanks

    Great video thanks Jonathan. I have 2 x 1300 litre tanks here in Perth. One with single tailed goldfish and the other has fantails. I find aquaponics is an easy, low maintenance way to keep fish in an outside pond. Plus you get bonus veg. I keep it simple with green leafy stuff and tomatoes which self seed. I feed my fish (yes, they all have names) skretting, especially made for aquaponics. It’s Aussie made and can be bought at – they can courier anywhere in Australia. Thanks again for the great content as usual 👍
