||This study investigated the different fermented vegetable protein(Source: defatted soy flour, rice bran, corn bran or seaweed Gracilaria)
on bass growth. Experimental control group feed use of whole fish meal as the protein source, and the rest of the experimental group feed fermented to lactic acid bacteria FPPH replace 30-45% of fish meal to reduce feed costs and detect the growth rate, increased weight gain and feed conversion rate and other parameters. Fish in their digestive tract of flora there is a close symbiotic relationship with the digestive tract flora in the digestive tract growth potential by antagonizing pathogens stimulate the host immune function, and synthesis for the host to use vitamins and digestive enzymes, so the favorable in maintaining the growth and health of the host. In this research, real-time earners perch juveniles stage probiotics (fermented substrate), will be able to promote to promote healthy digestive tract flora of perch to establish and improve resistance to disease and survival.
