Problems solved by technology

Crayfish is a bottom-dwelling crustacean with the habit of molting and cannibalism. It is difficult to increase the output of pond special breeding, and the utilization rate of ponds is low. Therefore, its products mainly come from paddy field cultivation, and pond cultivation is less; mandarin fish ponds are special cultivation , 1 mu of mandarin fish ponds, supporting about 4 mu of bait fish ponds, and because of the high density of mandarin fish breeding, there are many diseases, and often cause a large number of deaths due to diseases, resulting in losses

Abstract

The invention discloses a continuous breeding method for fry self-breeding of crayfishes and mandarin fishes through two ponds in a matched manner. The method comprises the first step of pond conditions, the second step of pond treatment, the third step of crayfish cultivation, the fourth step of crayfish catching, the fifth step of grass immersing and the sixth step of mandarin fish cultivation. According to the method, the crayfish and mandarin fish cultivation characteristics are fully utilized, the cultivation period is reasonably arranged, higher plants are planted to improve the environment and provide bait, the crayfishes are cultivated from March to June, and the mandarin fishes are cultivated from July to December; and meanwhile, crayfish fry breeding and mandarin fish fry cultivation are conducted, and the utilization efficiency and economic benefits of ponds are greatly increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for continuous cultivation of self-cultivating crayfish and mandarin fish with seedlings matched in two ponds. Background technique [0002] For a long time, the price of bulk fish has been low. In order to increase the economic benefits of pond farming and increase the yield of ponds, a large amount of feed and medicine have been invested, which threatens the environment and the quality of aquatic products. Crayfish (Procambarus clarkii) and mandarin fish are delicious and nutritious, and are deeply loved by consumers. Crayfish is a bottom-dwelling crustacean with the habit of molting and cannibalism. It is difficult to increase the output of pond special breeding, and the utilization rate of ponds is low. Therefore, its products mainly come from paddy field cultivation, and pond cultivation is less; mandarin fish ponds are special cultivation , 1 mu of mandarin fi...
