Method for improving anti-stress ability of fugu rubripes under different feed fat levels

Abstract

The invention relates to a method for improving the anti-stress ability of fugu rubripes under different feed fat levels, and belongs to the field of aquatic nutrition. The method aims at the problem that stress is prone to occurring in the fugu rubripes breeding process, a series of anti-stress substances including lysolecithin, taurine and L-carnitine are comprehensively applied, the content of substances such as arachidonic acid and phosphorus elements closely related to anti-stress metabolic signal transduction in feed is controlled, and therefore the resistance of bred fugu rubripes to a series of stress conditions such as high density and high temperature is improved. According to the method, the anti-stress ability of the bred fugu rubripes can be significantly improved, and accurate regulation and control under different feed fat conditions are achieved. Under the general background that high-density intensive breeding is increasingly prevalent, the breeding success rate can be increased, the production income can be increased, and development of intensive aquaculture can be supported from the perspective of nutriology.

Description

technical field [0001] The invention belongs to the field of aquatic nutrition, and in particular relates to a nutritional method for improving the anti-stress ability of redfin puffer under different feed fat levels. Background technique [0002] Unlike terrestrial animals, farmed fish live in water environments and are more susceptible to stress caused by changes in environmental conditions such as density, water temperature, and salinity. In particular, in the actual production process, the one-sided pursuit of output per unit of water in intensive farming often leads to high-density stress, and the uncontrollable natural water temperature in offshore cages and other farming models can easily lead to high or low temperature stress. For the redfin puffer, which is an important marine fish, its unique sharp teeth and strong cannibalism in the group will cause a high stress response even under general stress conditions. In production, it often leads to higher mortality and ...

Problems solved by technology

This method innovatively applies the anti-stress effect of lysolecithin combined with other nutrients, overcomes the low efficiency of a single anti-stress substance in feed, and overcomes the inefficiency of anti-stress strategies under different feed fat levels. The effect of the application is unstable, which makes up for the shortcomings of the existing technology in this field
