Feed for sturgeon parent fish as well as preparation method thereof

A technology of fish feed and sturgeon, which is applied in the field of sturgeon broodstock feed and its preparation, can solve problems affecting reproductive performance such as sturgeon spawning quantity and egg quality, affecting the quality of caviar of backup sturgeon, and fish body fat of sturgeon female broodstock. To avoid problems such as excess content, to achieve the effects of increasing suspension and attracting properties, improving feed conversion rate and specific growth rate, and improving the nutritional value and quality of eggs

Problems solved by technology

However, practice has proved that the existing sturgeon compound feed is too high in fat content to easily lead to excess body fat content of female sturgeon, and the phenomenon of "egg-in-oil" is prominent, which seriously affects reproductive performance such as spawning amount and egg quality of sturgeon. Affecting the quality of caviar in reserve sturgeon

Abstract

The invention discloses feed for sturgeon parent fish as well as a preparation method thereof. The feed is prepared from the following components in percentage by mass: 10 to 50 percent of fish meal,5 to 15 percent of chicken meat powder, 3 to 10 percent of egg powder, 1 to 5 percent of beer yeast powder, 5 to 30 percent of wet brine shrimps, 5 to 10 percent of conch meat, 5 to 10 percent of mussel meat, 5 to 10 percent of oysters, 8 to 25 percent of fermented soybean meal, 8 to 20 percent of flour, 1 to 4 percent of fish oil, 0.5 to 1 percent of soya lecithin powder, 1 to 5 percent of kelp powder, 0.2 to 1 percent of vitamin mixture, 1 to 5 percent of casein protein, 3 to 5 percent of antarctic krill, 1 to 4 percent of mineral element mixture, 1 to 5 percent of microbial agents, 1 to 5 percent of EPA, 1 to 5 percent of DHA, 1 to 5 percent of ARA, 1 to 5 percent of carotene, and 1 to 2 percent of feed attractant. According to the feed for the sturgeon parent fish, disclosed by the invention, a gonadal development condition of the sturgeon parent fish can be improved, a brood amount of sturgeon fish gonad is increased, the color of fish eggs is turned from common black into shallowcolor with a higher value amount, and even turned into scarce golden yellow fish eggs through the physiological metabolism so as to obtain excellent-quality sturgeon fish caviar; meanwhile, a survival ratio can be increased, a feed conversion ratio is increased and a specific growth ratio is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture. More specifically, it relates to a broodstock feed for sturgeon and a preparation method thereof. Background technique [0002] Sturgeon is one of the earliest vertebrates in existence.
