Problems solved by technology

[0006] However, the cultivation of loach seedlings is still in a relatively backward state. At present, natural seedlings and semi-natural seedlings are generally adopted in the soil method, and the spawning rate is low, the hatching rate is low, the seedling rate is low, and the emergence time is late, which is difficult to meet the needs of production.

Embodiment

[0019] The industrialized seedling raising method of loach of the present embodiment comprises the following steps:

[0020] (1) Temporary breeding of the loach. When the water temperature reaches about 10°C and the loach starts to move, choose a loach that is healthy, disease-free, and injured, and weighs more than 50g per tail, as the loach; After soaking in 25% sodium chloride solution for 5 minutes, put it into a cement pool with a depth of 1 meter. The pool is rectangular and the water body is about 20 cubic meters. Put about 30 tails per square meter, and put brown pieces in the pool as concealment. ; After the loach enters the pond, carry out nutrition strengthening, and feed soft pellet feed made of surimi, egg white, soybean meal, bran, etc. every day, and feed once a day in the morning and evening. Change the water continuously according to the situation. The water temperature starts from the natural water temperature, and the temperature is raised by 0.5°C every day...

Abstract

The invention discloses a loach industrial breeding method. The loach industrial breeding method includes temporary rearing of parent loaches, artificial stimulation for spawning, artificial breeding and advanced fry culturing. By means of the method, early fry emerging can be achieved, commercial scale can be achieved in the current year, the fry forming rate and the survival rate are high, and advanced fries are sound.

Description

[0001] technical field [0002] The invention belongs to the technical field of loach cultivation, and in particular relates to a method for industrialized seedling cultivation of loach. [0003] Background technique [0004] Loach is a small benthic fish. In the middle of the last century, loach was a low-value fish that could not be put on the table. However, since this century, loach has been loved by consumers because of its tender meat, delicious taste, and especially rich nutrition. Moreover, it is a commodity in short supply in the international market and one of the export products of my country's aquatic products. Therefore, the market price has increased greatly. The current market price is about 40 yuan per kilogram, which is almost equivalent to the market price of prawns. [0005] Because loach breeding is relatively easy, it can be monocultured or polycultured, and it can also be cultured in rice fields, lotus root ponds, etc., with fewer diseases and relativel...
