Application of euphausia superba powder in preparation of guppy color enhancing feed

Abstract

The invention discloses the application of a euphausia superba powder in preparation of a guppy color enhancing feed and the puppy color enhancing feed. The color enhancing feed is prepared through the following components in percent by mass: 5-75% of the euphausia superba powder, 1-20% of soybean protein concentrate, 1-8% of a barley pest powder, 1-8% of a cricket powder, 1-20% of self-raising flour, 2-10% of a beer yeast powder, 1-10% of starch, 4-20% of fairy shrimp, 2-4% of spirulina, 1-4% of soyabean lecithin, 2-4% of glycine betaine, 1-3% of soybean oil, 1-3% of a vitamin mixture, 1-5% of a mineral element mixture, 1-5% of an immunopotentiator, 0.1-4% of bacillus subtilis, 1-3% of rose, 0.5-2% of rhodopseudomonas palustris, and 2-4% of prodigiosin. The feed shows good color developing and enhancing effects on guppy; the flesh of guppy can be obviously improved after 5 days and the color is not faded; the feed is high in attracting performance, and capable of improving the immunity, the stress resistance and the survival rate.

Description

technical field [0001] The invention belongs to the technical field of aquaculture. More specifically, it relates to the application of Antarctic krill powder in the preparation of color-enhancing feed for guppies. Background technique [0002] Peacock medaka (Poecilia reticulata), commonly known as guppy fish, is a tropical fish belonging to the family medaka family.

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the existing color development and color enhancement technology in the breeding process of guppy and the problem of high fluorine content in Antarctic krill meal, prepare Antarctic krill meal with a fluorine content lower than 1mg / kg, and then optimize A special color-enhancing feed for guppies has been produced, which has a good color-enhancing effect on guppies. The fish body can take on a brilliant color without fading after eating for about 5 days. Food-attracting performance, easy to digest, no pollution to water quality, can significantly improve immunity, anti-stress ability, increase survival rate, significantly improve the economic benefits of guppy farming, and has a good application prospect
