Microecological preparation for improving growth performance of pampus argenteus juvenile fish and application of microecological preparation

Abstract

The invention relates to a microecological preparation applicable to pampus argenteus juvenile fish and application of the microecological preparation, and belongs to the technology of seawater fish type feed additive application. The invention aims at selecting probiotics applicable to the pampus argenteus juvenile fish for thus improving the growth performance of the pampus argenteus juvenile fish. By comparing and analyzing the safety and the beneficial function of bacillus subtilis, lactobacillus plantarum and clostridium butyricum, the condition that the bacillus subtilis does not have any harm to the pampus argenteus juvenile fish and has the best beneficial effect is found. The growth performance and the immunologic function of the pampus argenteus juvenile fish are obviously improved by the bacillus subtilis, so that the microecological preparation is recommended to be used in artificial culture of pampus argenteus.

Description

technical field [0001] The invention relates to a microecological preparation for improving the growth performance of silver pomfret juveniles and an application thereof, which belongs to the large-scale cultivation technology of seawater fish, in particular to the artificial cultivation technology of pomfret fish. Background technique [0002] Probiotics are a class of active microorganisms that are beneficial to the host. They can colonize the intestinal tract and exert a powerful probiotic effect by improving the intestinal microecological balance. So far, probiotics have been widely used in the fields of medicine and health care, food, feed, aquatic products and livestock and poultry breeding. In the field of aquaculture, probiotics can increase the yield of aquatic fish, reduce production costs, reduce the occurrence of diseases, treat intestinal inflammation, and thus improve economic benefits, so they have been generally recognized. In China, many experts and scholar...

AI Technical Summary

Problems solved by technology

Many commercial probiotics have poor probiotic effects in aquaculture, which may be due to the fact that these probiotics do not originate from aquatic animals or do not adapt to the intestinal tract of aquatic animals, and cannot maintain the scale of the flora in the intestinal tract

There is no report on the use of probiotics in silver pomfret farming
