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

Loach water breaker opening bait put into pond and breeding method thereof

Technical field

The present invention relates to a kind of loach fish bait, relate in particular to a kind of loach water breaker opening bait put into pond and breeding method thereof.

Background technology

Loach fish is the traditional outlet aquatic products kind of China, mainly sells to Korea S, Japan, Taiwan, Hong Kong and Southeast Asia one band.Recently more than ten years, the loach fish price rises year by year, and highest price reached 64 yuan/kilogram in 2008.

Loach water breaker opening bait put into pond and breeding method thereof are one of technology most crucial in the loach artificial propagation, directly determine the survival rate height of loach fry rearing.

Existing loach water breaker opening bait put into pond is:

1, soya-bean milk is exactly the swelling of soya bean water, then with throwing something and feeding behind soy bean milk making machine or the steel mill defibrination.

2, aioli is thrown something and fed with the egg or the duck's egg yolk defibrination that boil exactly.

3, milk powder is thrown something and fed with milk powder or other milk efflorescence slurry.

4, make compost in the pond with muck or other fertilizer on the pool under the rich water, cultivates plankton and ingest for the loach seedling.

5, mixing is thrown something and fed, and mixes with multiple bait such as soya-bean milk, aioli, milk powder and earthworm slurries and throws something and feeds.

Its shortcoming and defect is:

1, soya-bean milk, particle is tiny, vegetable protein, polluted-water, nutrition is general, can not satisfy the nutritional need of loach seedling.

2, aioli, particle is tiny, animal protein, polluted-water, nutrition is general, can not satisfy the nutritional need of loach seedling.

3, milk powder, particle is tiny, animal protein, polluted-water, comprehensive nutrition can partly satisfy the nutritional need of loach seedling in early days, and the middle and later periods can not be satisfied the nutritional need of loach seedling.

4, the pool under the rich water, animal protein, polluted-water, comprehensive nutrition can not satisfy the nutritional need of loach seedling in early days, and can satisfy the nutritional need of loach seedling mid-term, and the later stage can not be satisfied the nutritional need of loach seedling.

5, mixing is thrown something and fed, and particle is tiny, polluted-water, and animal/vegetable protein all has, and comprehensive nutrition can satisfy the nutritional need of loach, but palatability is poor, and it is low to cultivate the loach shoot survival percent.

Adopt its survival rate of above-mentioned loach water breaker opening bait put into pond between 0-30%.

Summary of the invention

Purpose of the present invention just is that overcoming prior art exists shortcoming and defect, provides a kind of loach water breaker opening bait put into pond and breeding method thereof.

Adopt bait provided by the invention can keep the survival rate on the pool under the loach spray more than 60%.

The object of the present invention is achieved like this:

By research loach spray than other general fish spray schistostoma the little and characteristics of ingestion ability difference, utilize bio-bacterial manure to cultivate the agreeable to the taste biological feed that is easy to get of loach spray---wheel animalcule, bait demand when satisfying the pool under the loach spray improves the survival rate on the pool under the loach spray.

1, pool optimal aperture bait under the loach fish spray

Pool optimal aperture bait is wheel animalcule under the loach fish spray; As long as in the water enough wheel animalcule density is arranged, the survival rate on the pool can improve greatly under the loach spray.

2, the breeding method of pool optimal aperture bait under the loach fish spray

This breeding method comprises the following steps:

1. under spray, before the pool, clear up Pond Silt,, kill noxious bacteria and virus the pond thorough disinfection;

2. in water, throw in an amount of bio-bacterial manure again;

3. throw in the loach spray after waiting the wheel animalcule that produces an amount of density in the water.

3, operation principle

The open-mouthed bait that utilizes pool the best under the loach spray is these characteristics of wheel animalcule, satisfies the needs of loach spray with bio-bacterial manure artificial culture wheel animalcule.Because great number of organic matters in the bio-bacterial manure decomposition and consumption water not only can be produced oxygen by photosynthesis, increase dissolved oxygen in water; And can satisfy the nutritional need of wheel animalcule by a large amount of bacterium of numerous life.

The present invention has following advantage and good effect:

1, the bait of Pei Yanging all is biological feed, comprehensive nutrition;

2, utilize the bacterial culture loach fish to like the wheel animalcule that eats, agreeable to the taste being easy to get;

3, bio-bacterial manure can photosynthesis, increases dissolved oxygen in water, keeps water quality pure and fresh;

4, the organic matter of bacterium in can accelerated decomposition water reduces water pollution and dissolved oxygen consumption;

5, bacterium can make full use of the inorganic matter synthesis of organic substance that decomposes in the water body, promotes material circulation in the water body.

Embodiment

Describe in detail below in conjunction with embodiment:

1, the refinement of this method

Step 2. in, described " in right amount " is meant the density according to the pool under the loach spray, what of bio-bacterial manure decision throw in.Generally be that 10 kilograms of EM bacterial manure, the following pool 50～600,000 loach sprays are thrown in every mu of pond.

Described " bio-bacterial manure " is meant the EM bacterium, and the EM bacterium is the english abbreviation of CEM, and the compound cultivation of kind of probiotics forms surplus 5 sections such as photosynthetic bacteria, lactic acid bacteria, saccharomycete, 10 genus 80.
