Problems solved by technology

At present, in the aquaculture industry, loach is a small species of fish, and there are not many studies on its seedling breeding and breeding. The main problems are: the ovary development of the breeding fish is inconsistent, and the egg production is low in the same period, which leads to the low hatching rate and the peak of bait cultivation. Inconsistent with the opening time of fry, the survival rate of fry is low

Embodiment

[0012] A kind of loach raising seedling culture technology, this technology comprises seedling raising, hatching, culture, it is characterized in that: carry out according to the following steps:

[0013] (1) Screen the site and build soil spawning ponds and seedling cultivation ponds;

[0014] (2) hatching, can adopt two kinds of modes, a), net cage lays eggs, and net cage hatches, and earth pond cultivates seedling, b), net cage lays eggs, and hatching barrel hatches, and earthen pond cultivates seed;

[0015] (3) Seed cultivation, fish fry are placed in earthen ponds or rice fields for seedling cultivation after swimming horizontally. 2 Release 800 seedlings, 20,000 seedlings per mu in the paddy field, sterilize with dibromohydantoin half a month before releasing the seedlings, the dosage is 2ppm, apply base fertilizer in the ring ditch after application, 500kg per mu, and then inject through a 60-mesh sieve Filtered water with an average water depth of 10cm. After the fry...

Abstract

The invention relates to a cultivation technology, in particular to a loach raising seedling cultivation technology, which pertains to the aquiculture and processing field. By screening the field for raising seedlings, hatch and raising seedling cultivation technology, the quality and the survival rate of fry can be improved efficiently, and industrialization can be realized, thus solving the difficult problem of loach seedling cultivation in the past well, satisfying the requirements of people to nature and good taste of aquatic products and leading the loach to become a delicacy on the table of common people.

Description

technical field [0001] The invention relates to aquaculture technology, in particular to a loach seedling raising and aquaculture technology, which belongs to the field of aquaculture processing. Background technique [0002] With the improvement of people's living standards, the variety and demand for aquatic products are also increasing. Loach is one of the most popular species among them. Loach is rich in high protein and trace elements. The meat is delicate and delicious. Loach is often eaten It can invigorate the kidney qi, fill the essence, warm the middle and lower qi, dredge the meridian and activate collaterals, strengthen the spleen and stomach. At present, in the aquaculture industry, loach is a small species of fish, and there are not many studies on its seedling breeding and breeding. The main problems are: the ovary development of the breeding fish is inconsistent, and the egg production is low in the same period, which leads to the low hatching rate and the pe...
