Embodiment Construction

[0015] According to the characteristics of the fish farming model, in order to control the experimental error, it is required that the environmental factors such as feed ingredients should be kept as consistent as possible throughout the breeding process, and the farming personnel should not be replaced. The specific operation steps are as follows:

[0016] (1) Experimental object: juvenile red tilapia fish from Yixing Base of Freshwater Fisheries Research Center of Chinese Academy of Fishery Sciences.

[0017] Breeding management: acclimation for one week before the experiment. Red tilapia juveniles of equal size were selected and divided into five groups, with 3 repetitions in each group, and a total of 15 cages. There are 20 tails in each cage, with a total weight of 141.2±0.6g and an average weight of 7.07±0.01g / tail. The juvenile fish were raised in cages in the pond of the Freshwater Fisheries Research Center, fed with different concentrations of bamboo carbon powder f...

Abstract

The invention discloses a feed capable of increasing content of unsaturated fatty acid in muscles of red tilapia and a feeding method of the feed. By adding 4 percent of bamboo charcoal component in the feed, the content of the unsaturated fatty acid in the muscles of the red tilapia can be significantly increased; and by feeding and contrasting the red tilapia with the feed provided by the invention, a result shows that the feed capable of increasing the content of the unsaturated fatty acid in the muscles of the red tilapia and the feeding method of the feed can increase content of the unsaturated fatty acid in the muscles of the red tilapia by 2.3 percent or more.

Description

technical field [0001] The invention belongs to the field of fish farming, and in particular relates to a feed for increasing the content of unsaturated fatty acids in red tilapia muscle and a feeding method thereof. Background technique [0002] Unsaturated fatty acids can reduce cholesterol and triglycerides in the blood that are harmful to the human body; can effectively control the concentration of blood lipids in the human body; and increase the content of high-density lipoproteins that are beneficial to the human body. Maintaining a low blood lipid level plays a key role in maintaining good health, preventing cardiovascular disease, and improving endocrine. The relevant reports are more common in sea fish, and the price is more expensive. If the content of unsaturated fatty acids in freshwater fish muscles can be increased, it will help the public to absorb unsaturated fats, thereby helping to improve people's health. [0003] Red tilapia (Oreochromis mossambicus×O.n...
