Suggested Fish for Use In Aquaponics
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.
Fish do not develop or grow identically. Some fish grow faster than others, and some are better suited for living in a closed-tank environment.
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 classification of cichlids that can be found all over the world. It is a freshwater fish with a docile flavor and can stay alive in holding tanks if some heating is given to preserve a consistent water temperature.
Tilapia feed primarily off aquatic vegetation and can easily reproduce in closed systems. Tilapia that has escaped into 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, a single 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 white bass can grow up to fifteen inches, but the average size for this species is nine 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.
Our third favorite is the crappie because of its delicately flavored meat and because of the fact that like the tilapia, it can adapt well to closed systems.
It is regrettable that unlike other fish, crappies require 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. The fertilized eggs are hatched unpretentiously in only ten days.
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 effortlessly grow your own vegetables and raise your own fish for nourishment, decor or for income. And, it can also be a great hobby.. This article, Suggested Fish for Use In Aquaponics is released under a creative commons attribution license.
