One oversight or one eminent weather advent can ruin a total season's glean. To cut the risk of complete loss and to exaggeration profits, some farmers are considering polyculture fish farming.
Description
Polyculture fish farming involves raising two or extra Supplementary species in one pond.
Considerations
There are few rules about which species you should choose if you want to begin a polyculture fish farm.

The tilapia will eat whatever they can at feeding time and the catfish will still get plenty of the food that falls to the bottom. The catfish will also eat any fry produced by the tilapia.
Compatibility
Even though two species have complementary ecological habits, they may not be good matches for polyculture fish farming. If the chosen species mature at different rates, they won't be ready to harvest at the same time. If one species is predatory, it may wipe out the other species over the course of the growing season. You can't raise prawns, which are harvested by draining the pond extreme of the season, with a species that reproduces and provides stock for the following season.
A acknowledged polyculture process Testament involve species that determine not compete for eats, mature at approximately the identical degree and may complement Everyone other's ecological habits.
