Abstract

The invention discloses loach water breaker opening bait put into a pond and a culture method thereof, relating to loach bait. The method selects a rotifer as the optimal loach water breaker opening bait put into the pond and the culture method comprises the following steps: (1) before water breaker is put into the pond, cleaning silt of the pond, thoroughly disinfecting the pond and killing harmful bacteria and viruses; (2) putting a proper amount of biological bacterial manure into water; and (3) putting loach water breaker after generating proper density of rotifers. The bait cultured by the method is biological bait and has all-round nutrition; the rotifers favored by the loaches are cultured by bacteria, palatable and easily obtained; biological bacterial manure can carry out photosynthesis to increase dissolved oxygen in water and keep the water quality fresh; and the bacteria can accelerate the decomposition of organic matters in water, reduce water body pollution and oxygen dissolved consumption, fully utilize inorganic matters decomposed in water body to synthesize organic matters and promote the circulation of matters in the water body.

Description

technical field

[0001] The invention relates to a loach bait, in particular to an opening bait for the loach and a cultivation method thereof. Background technique

[0002] Loach is a traditional export aquatic species in my country, mainly exported to South Korea, Japan, Taiwan, Hong Kong and Southeast Asia. In the past ten years, the price of loach has been increasing year by year, and the highest price in 2008 was 64 yuan / kg.

[0003] The bait for loach fish splashing in the pond and its breeding method are one of the core technologies in the artificial breeding of loach, which directly determines the survival rate of loach fry cultivation.

[0004] The existing bait for the opening of the loach water flower pond is:

[0005] 1. Soybean milk is to soak soybeans in water, then use a soybean milk machine or a steel mill to refine them and then feed them.

[0006] 2. Egg yolk pulp, which is to use boiled eggs or duck egg yolks to refine and feed.

[0007] 3. Milk powder,...
