Description

technical field [0001] The invention relates to a puffer fish feed, in particular to a puffer fish seedling feed 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 River. The blood, eyes, and...

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

First, puffer fish seedlings have low disease resistance; second, puffer fish seedlings are in a stage of vigorous metabolism and rapid growth and development. On the one hand, puffer fish seedlings in this period have a particularly large nutritional demand, and on the other hand, their digestive organs are underdeveloped. poor digestion
