In the process of high-density intensive breeding of golden pomfret, the breeding cycle is shortened, and the nutrients mainly come from compound feed. In addition, the effective pigment source in the feed is less and unstable, so golden pomfret cannot obtain sufficient natural pigment source, resulting in fish body The body color is not as bright as the natural individual, which seriously affects the value of the product
At present, in order to improve the body color of golden pomfret, artificial synthetic pigments are usually added to golden pomfret feed. These synthetic pigments cannot be eliminated from the body through the biodegradation of the fish itself or converted into harmless substances. crisis human health

Abstract
The invention provides trachinotus ovatus compound feed and a preparation method thereof. The trachinotus ovatus compound feed is prepared from basic feed and a coloring agent, wherein the coloring agent is prepared from pine needle leaves, sweet potato stems and leaves, green tangerine peels and wolfberry fruits in the weight ratio of (3-5) to (1-3) to (1-2) to (0.5-2). The method comprises the following steps: mixing and crushing the coloring agent and adding the basic feed; and uniformly mixing to obtain the trachinotus ovatus compound feed. According to the trachinotus ovatus compound feed, the four components including the pine needle leaves, the sweet potato stems and leaves, the green tangerine peels and the wolfberry fruits are added into conventional feed, so that pigment deposition of trachinotus ovatus can be remarkably improved, and furthermore, the trachinotus ovatus has a natural body color; and the survival rate of the trachinotus ovatus can be improved, the non-specificity immunity is enhanced, the growth of the trachinotus ovatus is accelerated and the food coefficient is reduced.
Description
technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a golden pomfret compound feed and a preparation method thereof. Background technique [0002] Golden Pomfret, scientific name Trachinotusovatus, is a famous and precious edible fish with high economic value. In the process of high-density intensive breeding of golden pomfret, the breeding cycle is shortened, and the nutrients mainly come from compound feed. In addition, the effective pigment source in the feed is less and unstable, so golden pomfret cannot obtain sufficient natural pigment source, resulting in fish body The body color is not as bright as the natural individual, which seriously affects the value of the product. At present, in order to improve the body color of golden pomfret, artificial synthetic pigments are usually added to golden pomfret feed. These synthetic pigments cannot be eliminated from the body through the biodegradation of the fish it...
