Abstract

The invention relates to the field of fish feeds, and provides a feed for improving the muscle quality of rainbow trout. The feed comprises, by weight, 30-35 parts of fish meal, 11-18 parts of Euphausia superba powder, 0.5-1.5 parts of composite vitamins, 0.5-1 part of composite vitamins, 0.3-0.5 parts of vitamin C, 0.2-0.4 parts of L-alanine, 0.2-0.6 parts of a composite microbial preparation, 0.05-0.4 parts of Haematococcus pluvialis powder, 0.1-0.6 parts of Carum carvi L and 0.1-0.5 parts of green tea polyphenol. The feed increases the content of natural astaxanthin in rainbow trout muscles, improves the quality and the nutrition values of the muscles, improves the growth performances of the rainbow trout, has increased utilization efficiency, and reduces the production cost.

Description

technical field [0001] The invention belongs to the field of fish feed, in particular to a feed for improving muscle quality of rainbow trout. Background technique [0002] The rainbow trout has a flat side, a large mouth, oblique clefts, and an end position. The snout is round and blunt, with fine teeth in the upper jaw. The base of the dorsal fin is short, and there is also a small adipose fin behind the dorsal fin. The pectoral fins are medium, with slightly pointed ends. Pelvic fins smaller, farther from anal fins. The scales are small and round. The back and top of the head are blue-green, yellow-green and brown, and the sides and abdomen are silvery white, white and off-white. Small black spots are irregularly distributed on the head, sides, back and fins. Sexually mature individuals have a purplish-red and pink, wide and bright red rainbow band along the lateral line, going straight to the base of the caudal fin, especially during the breeding season. Like a ra...
