Aquaponic Fish for filling up your aquaponics holding tanks, there are numerous aquaponic fish for you to choose from. Before you select the fish you are going to raise, you should do some research first to see which ones are best suited for the temperature, weather and basic conditions of the area you live in. Fish do not all grow and develop in the same way.
Fish do not all grow and develop in the same way. Some will grow much faster than others, while some are better for living in an environment that is closed. There are even freshwater fish that don't reproduce in holding tanks whatsoever. If you have chosen these aquaponic fish first, you'll wind up having to buy new fingerlings once the harvest is complete so that you can start the cycle again.
Let's take a look at the fish which are the most commonly seen used in aquaponic systems.
White Bass
This is a Midwestern species, and is a great edible species you should think about including. It is a carnivorous fish which can easily eat smaller fish and small crabs.
When found in the wild, one white bass is able to lay up to nine hundred thousand eggs in the season for active spawning. They do not care for the eggs after they are spawned. Instead, the adult will leave the spawning sites once the eggs are fertilized. They can grow to reach a length of fifteen inches, but on average they grow to nine inches.
White bass meat is cooked many times by smoking it, and is a favorite fish in the Midwest since it is easy to catch, especially while they are spawning.
Tilapia
This species of fish are classified as invasive, but it doesn't mean they shouldn't be included in aquaponic systems. You'll just have to take extra care to not release them accidentally into the wild, so that you can prevent the fish from competing with any native fish in the area. This is because tilapia can have a negative impact on the reproduction and growth of native species.
With some heating and a consistent water temperature, tilapia can survive well in holding tanks. They have a flavor which is mild, and they are in a group of cichlids which can be found around the world.
Tilapia can reproduce quite easily in a closed system, and will feed just about exclusively off of aquatic vegetation, making organic fish food an easy task with these fish. If they escape into the wild and reproduce with other tilapia species, they can reproduce hybrid tilapia.
Crappies
Third on the list of for aquaponic fish is crappies, since this fish has a flavor which is delicate, and since like tilapia, they will adapt very well to a closed system of living.
Unlike other fish, crappies unfortunately will need two years at least before you can expect them to be able to mate and reproduce. The male fish will protect the spawning site from any would-be intruders once the female has laid her eggs, and it only takes 10 days before the eggs which are fertilized will naturally hatch.
You should feed crappies small fish and insects if keeping them in a closed aquaponics system, since they are naturally carnivorous. You shouldn't put them in with larger fish like walleyes because these fish will prey on the crappies. You won't want to deal with the bigger fish nibbling the crappies.
