In modern commercial fish farming, special feed for fish is used at all stages of cultivation.
Pond and industrial fish farming
Fish breeding in pond fish farming is carried out in natural or artificial reservoirs. In order to maximize efficiency and significantly increase the yield of fish per hectare of water area, an intensive form of fish farming is used, in which carp and other herbivorous species are densely stocked (pcs/ha) and fully fed with mixed feed for fish.
Industrial fish farming involves breeding fish in cages and pools with dense planting. With this methodcultivation is carried out at a high speed of water circulation and full feeding with mixed feed for fish. With industrial fish farming, the largest increase in production volumes.
Compound feed groups for fish
