Culture methods and matters needing attention of plain sailing fish

Breeding seedlings: the pond should be disinfected before raising seedlings, and then base fertilizer should be applied. Cultured adult fish: plain sailing fish has strong adaptability, gentle temperament, can be raised alone, can also be mixed with grass carp, bighead carp, carp, and so on. Feeding and management: the water quality should be kept clean and fat, and the feed of adult fish is mainly water earthworms, with small fish and shrimp, livestock and poultry viscera, clams, snails and so on. Prevention and control of diseases and insect pests: common diseases are Gill rot, parasitic diseases, enteritis, malnutrition, flooding and so on.

First, to cultivate seedlings

The main results are as follows: 1. The fry can grow to about 3-5cm after 30 days of emergence, and the main food is benthic invertebrates.

2. The area of the culture pond is about 1-2 mu and the water depth is about 1.2-1.5 m. Before the fry is released, the pond should be disinfected, then base fertilizer should be applied, and finally concentrate feed, such as eel feed, peanut bran, water earthworm and so on.

Second, cultured adult fish

The main results are as follows: 1. Plain sailing fish has good disease resistance, strong adaptability, miscellaneous eating habits, gentle sex and so on, so it can be raised either alone or mixed.

2. Monoculture: about 400-600 large fish species can be raised per mu, and then make full use of water body and feed to supplement some other species such as feeding habits and perching water layer.

3. The amount of input per mu is about 200-300 fish, and can be mixed with other fish, such as silver carp, grass carp, bighead carp, carp, etc., each about 30-50 fish. In addition, in order to increase the income of the pond, it can be used as matching fish, a small proportion of which can be put in other culture ponds.

III. Feeding and management

In the later stage, we need to strengthen management, and we must keep the water quality clear, cool and fat. in addition, we should feed reasonably. Adult fish feed is mainly fed with water earthworms, and it can also be matched with small fish and shrimp, livestock and poultry viscera, clams, snails, and so on. The crude protein content of artificial pellet feed needs to reach more than 35%, and eel feed can be mixed with chilled fish paste to feed.

IV. Prevention and control of diseases and insect pests

The main results are as follows: 1. Plain sailing fish grow under natural conditions, have good disease resistance, and basically have few diseases. such as artificial feeding, diseases generally occur in fry, fry, adult fish and other stages. the common diseases are Gill rot, parasitic diseases, enteritis, malnutrition, flooding and so on. Therefore, in order to control the occurrence of diseases, comprehensive prevention and control measures should be taken.

2. Method of operation: scientific feeding method should be adopted to feed, disinfect the food farm, feed, fish pond and fish species regularly, sprinkle insecticidal and bactericidal drugs once a month, and disinfect twice a month in the high incidence season from April to September and September to October. In order to prevent disease, one course of medicine and bait can be fed at the same time.
