Feed for improving globefish meat quality

Abstract

The invention provides feed for improving globefish meat quality. The feed is prepared from the following components: corn flour, wheat bran, rice bran, Glycine max stem leaf powder, soybean protein powder, flour, fish meal, bone meal, complex vitamins, complex multiple mineral elements, and a core additive; the core additive is prepared from the following components: tuber fleece-flower roots, eucommia barks, licorice, dark plums, morning glory seeds, eclipta herbs, moutan barks, and rose flowers. The feed can provide basic nutrients for globefish marketable fish and promote rapid growth of globefish marketable fish; the core additive is added for improving globefish to aestivate and ingest food, improving growth efficiency of globefish marketable fish, and improving immunity of the globefish marketable fish; the feed has the advantages of high safety, wide raw material sources, and low cost.

Description

technical field [0001] The invention relates to a feed for puffer fish, in particular to a feed for improving the meat quality of puffer fish and its preparation method and application. Background technique [0002] Pufferfish belongs to Fuguformes, Fugu suborder, Fuguidae, Puffer genus. There are 19 species in China. Wild puffer fish is a kind of highly poisonous fish, and its consumption is strictly restricted. [0003] Fugu obscurus has a large output and is a river-sea migratory fish. It occupies a certain proportion in the entire Yangtze River fishery and has a certain economic value. Every spring, groups of sexually mature broodstock enter the freshwater lake system in the middle and lower reaches of the Yangtze River from the East China Sea to spawn; the young fish are fattened in fresh water and return to the sea around October of that year. Food habits are miscellaneous, partial animal. This fish tastes very fresh and is one of the three delicacies of the Yangtze...

AI Technical Summary

Problems solved by technology

There are at least four deficiencies in this breeding method: 1. Poor cohesiveness of powder feed, severe dissolution in water, and large waste, resulting in deterioration of water quality and low survival rate of puffer fish; 2. A large amount of labor costs; 3. Individual It is difficult for farmers to quickly expand the scale of farming; 4. Since the amount of fishmeal used in eel feed is as high as 50%, the high content of phosphorus in fishmeal cannot be fully utilized and discharged into the aquaculture water body, resulting in eutrophication of the aquaculture water body, red tide, algae bloom, etc. problems happen from time to time
