Problems solved by technology

Although the existing patent uses two feedstuffs with significant difference in ratio to alternately feed the yellow catfish, although the characteristics of the yellow catfish compensation growth can be used to a certain extent, it also makes the yellow catfish juveniles Under constant plant protein stress, it is potentially harmful to the physiological function of juvenile fish and is not conducive to the growth and development of juvenile fish

Abstract

The invention belongs to the technical field of fish heredity nutriology, and particularly relates to pelteobagrus fulvidraco larva fish high in vegetable protein tolerance and a cultivating method ofthe pelteobagrus fulvidraco larva fish high in vegetable protein tolerance. According to the method, the principle combining heredity nutriology and biological breeding science is adopted, through experiment, a technical system for cultivating pelteobagrus fulvidraco fry varieties high in vegetable protein tolerance is obtained. Pelteobagrus fulvidraco larva fish after 3-15dph of incubation and film outlet are fed with a compounded high-vegetable protein inducing feed, appropriate-duration vegetable protein feed short time stimulus is given (feeding stimulus duration of the high vegetable protein feed is between 5-15 days), and pelteobagrus fulvidraco juvenile fish fry varieties which do not have significant differences from a non-stimulus group in specific growth rate, are higher than the non-stimulus group in nonspecific immunity capacity with digestive absorption capacity or do not have significant differences from the non-stimulus group in the nonspecific immunity capacity and thedigestive absorption capacity can be obtained. In the respect of feed cost, through the high-level vegetable protein, the feed cost can be significantly reduced, the production cost can be saved, andthe breeding benefits can be increased.

Description

technical field [0001] The invention belongs to the technical field of fish genetic nutrition, in particular to a high plant protein tolerant yellow catfish larvae and a breeding method thereof. Background technique [0002] my country is a big aquaculture country. The rapid development of intensive aquaculture has further increased the demand for fishmeal in the aquaculture industry. The limited supply of fishmeal and the strong dependence of farmed fish, especially carnivorous fish, on fishmeal have become restrictions on my country's aquatic products. The main factor of sustainable development of aquaculture. Substituting cheap plant protein for fish meal as feed protein source can effectively save feed cost, but a large number of studies have shown that high-level plant protein or complete level of fish meal replacement will cause irreversible damage to fish body metabolism and immunity. This effect is particularly evident in carnivorous fish. Therefore, in the case of ...
