Embodiment Construction

[0026] This embodiment is the seedling raising test that the applicant carried out in Muping breeding base in Shandong Province.

[0027] (1) The hatching stage of eye-catching eggs

[0028] The invention uses a tray-shaped incubator, and adopts a running water hatching method in the incubator. The aquaculture water meets the fishery water quality standard (GB11607-89), and the carbon dioxide CO is removed by jet aeration first. 2 , use absorbent cotton to filter suspended particles, and the water quality requirements are less than 1.5mg / L for ammonia nitrogen, less than 1.5mg / L for nitrite, and CO 2 Less than 18mg / L. If ammonia nitrogen and nitrite are too high, the number of red blood cells and hemoglobin in the fish will decrease, and the oxygen-carrying capacity of the blood will be poor, thereby damaging the tissues and organs of the fish and causing the death of the fish; CO 2 Excessive concentrations can cause air bubble disease and nephrocalcinosis in Atlantic salmo...

Abstract

The invention discloses a migratory Atlantic salmon factory-like artificial breeding method. The migratory Atlantic salmon factory-like artificial breeding method includes the eyed egg incubation stage, the mouth opening and feeding stage, the fry breeding stage and the silvering process stage. Eyed eggs are incubated in an incubator in an incubation room with running fresh water; in the mouth opening and feeding stage, Atlantic salmon fries are bred in an indoor breeding pond with running fresh water; in the fry breeding stage, indoor closed circulating fresh water breeding is performed; in the silvering process stage, indoor closed circulating fresh water breeding is performed, the silvering process includes the silvering period and the lighting recovery period, the silvering period of five weeks begins first, during the silvering period, it is bright for 12 hours and dark for 12 hours every day, then the lighting recovery period of fives weeks begins, and 24-hour lighting is performed every day during the lighting recovery period. In the breeding process, the Atlantic salmon fries are all incubated and bred indoors, so that incubation and breeding are free of weather influences, the incubation and breeding conditions can be manually controlled conveniently, large-scale breeding can be carried out, the breeding is stable, the survival rate of the fries is high, the fries are uniform in size, and high-density breeding can be achieved.

Description

technical field [0001] The invention relates to an industrial artificial seedling raising method, in particular to an industrial artificial seedling raising method for migratory Atlantic salmon, and belongs to the technical field of aquatic seedling raising. Background technique [0002] Atlantic Salmon ( salmo salar.L ) belonging to the family Salmonidae ( Salmonoidea ) Salmon ( Salmon ), commonly known as salmon, is a cold-water fish. According to their different living habits, they can be divided into two types: migratory type and land sealing type. The artificial breeding of migratory Atlantic salmon is carried out in fresh water, and the adult fish breeding stage is carried out in seawater, which is essentially different from the land-sealed Atlantic salmon that has been cultured in fresh water for a lifetime. Migratory Atlantic salmon is more suitable for intensive farming, which is characterized by high economic value, fast growth and strong disease resistance. ...
