Embodiment 1

[0017] Example 1. Use this method to increase the muscle fat of puffer puffer. Experiment 1

[0018] 1. Experimental design and experimental feed formula

[0019] Based on formula 1, which is common in the market for seawater fish, 500 mg / kg astaxanthin was added to the basic formula, and the amount of methionine in the feed was controlled to 0.56% (accounting for the proportion of dry matter in the feed). The control group was fed with common commercial compound feed. The feed formulation is shown in Table 1.

[0031] Example 2. Use this method to increase the muscle fat of puffer puffer. Experiment 2

[0032] 1. Experimental design and experimental feed formula

[0033] Based on the common seawater fish formula on the market (this reference formula does not belong to the scope of protection of this patent application), add 500 mg / kg astaxanthin to the basic formula, and control the amount of methionine in the feed to 0.67% (accounting for Feed dry matter mass specific gravity). The control group was fed with common commercial compound feed. The feed formulation is shown in Table 2.

[0047] 1. Experimental design and experimental feed formula

[0048] Add 100 mg / kg astaxanthin to the basic experimental formula (this formula does not belong to the scope of protection of this patent application), and control the amount of methionine in the feed to 1.6% (accounting for the proportion of dry matter in the feed). The control group was fed with common commercial compound feed. The feed formulation is shown in Table 3.

Abstract

A nutritional method for regulating the muscle fat deposition of red-finned puffer, which belongs to the field of nutritional feed for aquatic animals. High or low fat content in the muscle of cultured redfin pufferfish. The method of the invention makes it possible to regulate the fat content in the muscle of the redfin puffer. The method is green and environment-friendly, does not produce any toxic by-products, does not affect food safety, and the cost is 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 method of regulating and controlling red fin puffer ( Takifugurubripes ) Nutritional approach to muscle fat deposition. Background technique [0002] The red-fin puffer is a kind of puffer fish, with delicious meat, 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 have been strictly controlled. Although my country is a big puffer breeding country, its products were mainly exported to Japan and South Korea in the past. In October 2016, as the General Office of the Ministry of Agriculture of China and the State Food and Drug Administration jointly issued the "Notice on Conditionally Liberating the Processing and Operation of Pufferfish and Pufferfish Obscura", the circulation of pufferfish in China and consumpt...
