Embodiment 1

[0016] Example 1. Use this method to increase the muscle fat of puffer puffer. Experiment 1

[0017] 1. Experimental design and experimental feed formula

[0018] Take the common seawater fish formula on the market as the basic formula one, add 500mg / kg astaxanthin in the basic formula, and control the amount of methionine in the feed to 0.56% (accounting for the dry matter mass proportion of the feed). The control group was fed with common commercial compound feed. The feed formulation is shown in Table 1.

Abstract

The invention discloses a nutriology method for regulating fat deposition in muscle of Takifugurubripes, and belongs to the field of nutrition feed of aquatic animals. According to the method, a certain amount of astaxanthin is added to the feed of Takifugurubripes, and the content of methionine is controlled, so that the fat content in muscle of bred Takifugurubripes is raised or reduced. Throughthe method, directional regulation of the fat content in the muscle of Takifugurubripes is made possible, and the method is environmentally friendly, does not produce toxic by-products at all, does not affect food safety, and has cost within a controllable range.

Description

technical field [0001] The invention belongs to the field of nutritional feed for aquatic animals, and in particular relates to a nutritional method for regulating and controlling muscle fat deposition of red fin puffer (Takifugurubripes). Background technique [0002] The red fin puffer is a kind of puffer fish, the meat is delicious, and it occupies an important position in the traditional food culture of our country. For a long time, due to the peculiar tetrodotoxin of puffer fish, its market circulation and consumption are strictly controlled. Although my country is a big puffer breeding country, its products were mainly exported to Japan and South Korea in the past. Pufferfish is one of the few cultured fish in my country that uses fish fillets as the main eating method, which puts forward higher requirements for the quality of pufferfish muscle. The amount of fat deposition is the most important determinant of puffer puffer muscle quality. Due to the restrictions on...
