What are the types of freshwater fish? Freshwater fish are divided into edible and ornamental freshwater fish. Ornamental freshwater fish mainly include goldfish, angelfish, zebrafish, seven-star knife fish, koi and other varieties. Edible freshwater fish mainly include black carp, grass carp, carp, crucian carp and other varieties. Among them, black carp is mainly distributed in the south of the Yangtze River in my country. It grows faster and has more delicious meat. It is an important source of fishery resources. Grass carp is a herbivorous fish that mainly lives in rivers and lakes in plain areas. It grows rapidly and has a wide range of diet. It accounts for a large proportion of my country's freshwater fish farming.

Carp is the most widely distributed and diverse freshwater fish, and the carp has a long history of breeding. Carp is an omnivorous fish that is relatively resistant to low temperatures and can quickly adapt to water quality. It is a common edible fish in my country. Crucian carp mainly feeds on aquatic plants or plankton. Its meat contains a large amount of trace elements and minerals, and it is inexpensive and of good quality, making it an indispensable delicacy on the Chinese table.

2. How to raise freshwater fish There are many ways to raise freshwater fish, the most common of which is to raise fish in rice fields or ponds. The most important thing about raising fish in rice fields is to prevent the fish from escaping, so before stocking, the ridges need to be raised and fish ditches need to be dug so that the fish can hide when fertilizing or spraying pesticides. Pond fish need to be disinfected first, and the best way is to dissolve and spray lime or jujube bleaching powder. After putting in the fry, ensure that there is enough food, and mix them reasonably, and prevent diseases and eliminate pests in time.
