Embodiment

[0019] This example is mainly to analyze the probiotic effect of the lactic acid bacteria "Yibacteria No. 1" on the growth and disease resistance of young flat scorpionfish. By feeding the juvenile flat scorpionfish with lactic acid bacteria "Yibacteria No. 1" feed (experimental group), and at the same time feeding the feed group without "Yibacteria No. 1" as a control, the analysis of "Yibacteria No. 1" Effects on the growth of Pleurotus xushii; after the feeding experiment, use Vibrio anguillarum to infect the juveniles of Pleurotus xushii in the experimental group and the control group, observe the survival status of the juveniles in each group, and detect the liver removal of pathogenic bacteria in the juvenile fishes of each group. ability.

Abstract

The invention discloses a micro-ecological preparation for improving the growth and disease resistance performance of sebastes schlegeli juvenile fish and an application method. The micro-ecological preparation is characterized by comprising lactic acid bacteria with the China General Microbiological Culture Collection Center (CGMCC) number of No. 15649; the concentration is equal to 1*10<5> CFU / g. The lactic acid bacteria have no dangers on the sebastes schlegeli juvenile fish and have a relatively good probiotic effect; the growth performance and disease resistance of the sebastes schlegelijuvenile fish can be remarkably improved.

Description

technical field [0001] The invention relates to a micro-ecological preparation and an application method for improving the growth and disease resistance performance of juvenile flat scorpionfish, belonging to the large-scale cultivation technology of seawater fish, in particular to the artificial cultivation technology of flat scorpionfish. Background technique [0002] Probiotics are a class of active microorganisms or microbial preparations that are beneficial to the host. They can colonize the intestinal tract and exert a powerful probiotic effect by improving the intestinal microecological balance. The application of probiotics mainly involved the fields of food, medicine, feed industry and cosmetics at the earliest. The application research in aquaculture started relatively late, and the relevant research reports gradually increased after the 1980s. The application of probiotics as additives in aquaculture will not produce adverse side effects such as contamination of d...
