? Big head fish is one of the common fish in our country. It lives in freshwater basins and is an edible fish. Because of their high economic value, many breeders choose to breed them. Big head fish is relatively easy to raise, one of the important reasons is that they are not picky eaters, are omnivorous fish, many foods can be eaten. Some people think that big head fish will eat the feces of grass carp, which is not very accurate. The big head fish does not directly eat the feces of grass carp, but eats some phytoplankton and algae that promote the growth of grass carp feces. That is to say, if there is grass carp feces in the water, the phytoplankton and other plants in the water will be more abundant, the food of the big head fish will be more abundant, and their growth will be better.
In fact, not only the excrement of grass carp, but also the excrement of other fish and even human excrement. If there are these substances in the water, then the plankton will be more abundant, and the big head fish is using these plankton as food, so the food of the big head fish is more abundant.
with grass carp? It has been introduced above that big head fish is one of the fish that can be cultured in our country. To breed big head fish, sometimes it is a single fish, and sometimes it is a polyculture. There are many fish that can be mixed with big head fish, and grass carp is one of them. The habits and characteristics of big head fish and grass carp are not very different, so it is not a big problem to raise them together. Attention should be paid to the problem of density, not too dense, if the number is too large, it will lead to insufficient oxygen content in the water, or insufficient food, which is harmful to the growth and development of both fish.
