Problems solved by technology

[0005] But so far, the industry has not carried out research on other aspects of Pacific cod reproduction biology, artificial breeding and breeding, so it is necessary to carry out biological research on Pacific cod as soon as possible to provide a theoretical basis for further research on this important economic fish

Embodiment Construction

[0017] Specific embodiments of the present invention will be described below.

[0018] A method for artificial seed cultivation of Pacific cod, the method mainly includes pre-feeding and post-feeding cultivation of larvae, during which the cultivation water temperature is 10±1°C and the light is Control at 500-1000lx, cultivate water salinity 32,

[0019] Cultivation before feeding:

[0020] Emergence: Before a large number of membranes rupture, there will be a lot of foam floating on the water surface in the hatching tank (under normal circumstances, the foam covers the entire water surface, and the water can hardly be seen). When this phenomenon occurs, you can consider changing the water appropriately or not changing the water , Try to shorten the emergence time. According to experience in previous years, lowering the incubation temperature before the rupture of the membrane will make the emergence of seedlings relatively concentrated and easy to manage.

[0021] Seedlin...

Abstract

The invention discloses an artificial fry rearing method for gadus macrocephalus. In the industry, researches on the gadus macrocephalus with significant economic values are still in blank, and researches on reproductive biology, artificial breeding, proliferation and the like of the gadus macrocephalus are not developed yet. The artificial fry rearing method for the gadus macrocephalus has the advantages that fries of gadus macrocephalus can be cultivated to adult fish successfully, fish fry quality can be improved, survival rate can be guaranteed, industrialized production can be realized smoothly, and theoretical foundation and technical support are provided for large-scale aquaculture of the gadus macrocephalus.

Description

technical field [0001] The invention relates to a method for cultivating fish, in particular to a method for cultivating artificial seedlings of Pacific cod. Background technique [0002] Pacific Cod ( Gadus macrocephalus ) belongs to the order Gadiformes, the family Gadidae, the genus Cod ( Gadus ), English name Pacific cod, also known as cod, commonly known as cod in Shandong, Liaoning and other places. [0003] In Norway, Finland, Denmark, the United Kingdom, Canada, the United States and other countries, the research on Atlantic cod biology has been recorded as early as the beginning of the 19th century, and it reached its peak in the early 1990s, and considerable progress has been made. . Over the past ten years, countries such as Norway, the United Kingdom, Canada and Iceland have invested heavily in the research and development of Atlantic cod breeding technology, and have formed a complete set of artificial breeding and breeding models. It is an important breedi...
