Example Embodiment

[0014] The specific method steps for cultivating the first-year large-size seedlings of the pollution-free "four major home fish" in a pond of 1 mu are as follows:

[0015] A: Pond pretreatment: Drain the pond water in winter, expose the bottom of the pond to the sun for 10 days, and dilute it with 50 kilograms of quicklime to fill the pond and splash it to kill pathogens in the pond. Pile up 300 kilograms of green grass and 250 kilograms of pig and sheep manure in the pond, mix them thoroughly, and pile them in the pond for fermentation to cultivate organic bait. Fill the pond with water after 5 days of composting. Use a soft hose to insert the water into the water during irrigation. Use a fine screen to filter the water to prevent wild fish from entering the pond and hinder the growth of domestic fish. The depth of the irrigation water is controlled at 0.4m, and the seedlings will be stocked 6 hours after irrigation.

[0016] B: Seedling stocking: On May 10, 66,000 green, grass,...

Abstract

A method for culturing one-instar fry of black carp, grass carp, silver carp and variegated carp includes choosing rarieties, pretreating pond, proportionally culturing them in a single pond, regulating water quality, and scientifically applying feed and fertilizer.

Description

Technical field [0001] The invention relates to a method for cultivating fish, in particular to a method for cultivating one-year-old large-size seedlings of the pollution-free "four major family carps". Background technique [0002] "Four major fish" refer to herring, grass carp, silver carp and bighead carp. It is a special freshwater economic fish in my country. It has excellent characteristics such as fast growth, large body, good meat quality and strong stress resistance. Its aquaculture production accounts for about 70% of the national freshwater fish aquaculture production. It is the main source of fish protein needed by the general public, and has already become the main species of freshwater aquaculture. With the continuous expansion of the breeding scale of the "Four Major Fishes", the cumbersome breeding process of the Four Great Fishes does not match the ecological conditions, resulting in slow growth, small individuals and many diseases. In particular, the gr...
