The following eight kinds of fish are the most common freshwater cultured fish, which can be cultured in ponds, namely grass carp, herring, silver carp, bighead carp, carp, crucian carp, bream and bream.

Why are rural ponds suitable for raising these eight kinds of fish? Because they have these advantages suitable for pond culture.

1, the bait source is wide. Generally speaking, there are various phytoplankton and animals as well as some aquatic plants and benthos in the pond water. These eight kinds of fish have simple feeding habits, some directly eat phytoplankton and aquatic plants, and some mainly eat zooplankton and benthos, so the bait sources are extensive.

2. Fast growth. These eight kinds of fish are delicious, marketable, stable in price, big in size and fast in growth.

3. Strong adaptability. These eight species of fish belong to Cyprinidae, which are warm-blooded fish. They have a large number of eggs, strong reproductive ability, mature artificial propagation technology, abundant source of fry, strong disease resistance, long history of artificial propagation and relatively stable and mature technology.

4, the breeding method is flexible. These eight kinds of fish can be intensively cultured or coarsely cultured in ponds, and can be fed with artificial bait or commercial fish feed.

These eight kinds of fish can be raised separately or mixed in the same pond. Their habitats are silver carp, bighead carp, bighead carp, snakehead, grass carp, herring, carp and crucian carp from top to bottom. Reasonable collocation and polyculture can also promote each other's growth. For example, the residual bait of grass carp and herring can be used to feed carp, crucian carp, bream and snakehead, and their feces can be used to feed silver carp and bighead carp. Silver carp and bighead carp eat plankton, which reduces the fertility of water, while carp and crucian carp can clean the feeding grounds, which is beneficial to grass carp and bighead carp.
