Abstract

The present invention belongs to the technical field of aquaculture feeds and discloses a feed curing fatty liver of pseudosciaena crocea and a preparation method thereof. The preparation method comprises pretreating, extruding and puffing, spraying, drying and cooling. The preparation method is short in production cycles, simple, and low in energy consumption. Besides, the prepared feed greatly preserves active ingredients of raw materials, is high in quality, stable in properties in water, rich in nutrient components and good in palatability, can regulate a metabolism of fat in pseudosciaena crocea bodies, can prevent or restore liver health, can also effectively enhance body constitution of the pseudosciaena crocea, and improves immunity and body color.

Description

technical field [0001] The invention belongs to the technical field of aquaculture feed, and in particular relates to a feed capable of improving fatty liver of large yellow croaker and a preparation method thereof. Background technique [0002] Large yellow croaker, elongated body, flat sides, about 40-50cm in length, golden yellow, slender caudal peduncle, small scales, 8-9 rows of scales from the starting point of the dorsal fin to the lateral line, 25-27 vertebrae. It usually lives in deep sea areas. It migrates to the sea to spawn from April to June. After spawning, it disperses along the coast for bait, feeds on fish and shrimp, etc., and migrates to deep sea areas in autumn and winter. The swim bladder can make sounds, fishermen often use this to estimate The size of the fish school is distributed in the South China Sea, the East China Sea and the southern part of the Yellow Sea. It is an important economic fish in China, and it is used for fresh food or for making y...
