Problems solved by technology

[0007] The purpose of the present invention is to overcome the shortcomings of the existing bait that is not conducive to the digestion and absorption of prawn larvae and the water pollution caused by bait collapsing in water, and to provide a method of enzymatically hydrolyzing protein and adding Chinese herbal medicine extracts, which can improve the effect of digestion and absorption of prawn larvae, The microcapsule opening bait that improves the immunity of larvae can realize the application of insect protein source in the opening bait of prawn larvae at the same time, open up the treasure house of insect protein source, and alleviate the dependence on fish meal. The invention also solves the problem of prawn larvae The problem of water pollution caused by open bait collapsing in water

Abstract

The invention discloses microcapsule initial feed for prawn larva cultivation. The microcapsule initial feed for the prawn larva cultivation comprises, by weight, the following raw material components: 20-40% of enzymolysis barley pest thick liquid, 10-25% of fish meal, 5-10% of shrimp chaff, 10-25% of bean pulp, 1-5% of fairy shrimps, 1-6% of yeast powder, 0.5-2% of lecithin, 0.5-2% of fish oil, 0.4-1% of monocalcium phosphate, 1-20% of gelatin, 5-20% of maltodextrin, 0-2% of sodium carboxymethylcellulose, 0.1-2% of Chinese herbal medicine polysaccharide, and 1-10% of additive agent. The microcapsule initial feed for the prawn larva cultivation can greatly improve the growth speed, the metamorphosis rate and the immunocompetence of prawn larvae, and by means of a microcapsule manufacturing technique, the problem of water pollution caused by scattering of feed is solved.

Description

technical field [0001] The invention relates to an aquaculture bait, in particular to a microcapsule opening bait for culturing juvenile shrimp. Background technique [0002] The freshwater culture of Penaeus vannamei in my country has developed rapidly, and it has been cultured from south to north and from east to west. The culture of Penaeus vannamei in the Xinjiang Plateau has also been successful. In 2005, the output of freshwater aquaculture reached 440,800 tons, 8.15% higher than that of marine aquaculture. The national marine and freshwater aquaculture output of Penaeus vannamei reached 848,400 tons. [0003] In the traditional shrimp nursery, plankton is mainly relied on as the bait for shrimp fry, which is often limited by aquatic biological resources and nursery sites, and the production effect of the nursery is unstable. Now more and more farmers use fishmeal-based granular bait with antibiotics, which has caused a series of resource and environmental problems. ...
