It is suggested that you research which fish are best suited to the weather, temperature, and general conditions of your location before you decide which of the several freshwater fish you want to use to stock in your aquaponic holding tanks.
Some fish are better suited for the closed-tank environment than others because they do not grow or develop at the same rate. Some fish just grow faster than others.
Some freshwater fish do not reproduce in holding tanks at all. If you selected those fish, you’d have to buy additional fingerlings after a harvest in order to begin the cycle anew.
Tilapia is an invasive species. However, they are not to be avoided. In fact they are a favorite in aquaponics. You do have to be careful not to accidentally release tilapia into the wild to prevent them from competing with native species. Tilapia can have a negative impact on the growth and reproduction of native species.
Tilapia is a mild-flavored freshwater fish that can survive in holding tanks if some heating is given to uphold a consistent water temperature. Tilapia is a group of cichlids that can be located all over the world.
Tilapia mainly eats aquatic vegetation and can easily replicate in closed systems. Tilapia in the wild can reproduce hybrid tilapia if they are able to mate with other tilapia species.
A Midwestern species, the white bass is an excellent edible fish species that you should also consider stocking. Unlike the tilapia, the white bass is carnivorous and it can feed easily on small crabs and smaller fish.
In the wild, one white bass can lay as many 900,000 eggs during the active spawning season. No care is given to the eggs after the spawning. The adult white bass leave the spawning sites after the eggs have been fertilized. The average size of the white bass is 9 inches, but they can grow up to fifteen inches.
The white bass is often cooked through smoking and is a crowd favorite in the Midwest, due to the fact that white bass is not hard to catch at all, especially during the spawning season.
A third preference is the crappie because of its elegantly flavored meat and like the tilapia it can acclimate well to closed systems.
Unfortunately, crappies (unlike other fish) need at least two years before they are able to mate and reproduce. Once the female crappie lays her eggs, the male partner protects the spawning site from intruders. It only takes ten days before the fertilized eggs are hatched naturally.
Carnivorous by nature, crappies should be fed insects and small fish if they are kept in a closed system like a fish tank. Avoid stocking crappies with larger fish such as walleyes as these larger fish will actually prey upon crappies. You wouldn’t want to deal with larger fish nibbling on your crappies.
With aquaponics you can easily grow your own produce and raise your own fish for nourishment, decoration or for monetary gain. And, it can also be a great hobby.. This article, Fish To Use In Aquaponics is released under a creative commons attribution license.
