Embodiment 2

[0021] Preparation method: Candida utilis, Enterococcus faecalis: Lactobacillus acidophilus: Bacillus subtilis= =1:2:2:1, mix the above-mentioned strains and ferment in the culture medium at a constant temperature of 15% by mass, and stir while passing oxygen. The initial temperature of the culture is 28°C for 24 hours, and 30°C for 24 hours. , Cultivate at 35°C for 12 hours until the fermentation culture reaches a pH value of 3. The culture medium is 0.5 g of agar, 0.5 g of beef extract, 2 g of yeast extract, 30 g of sucrose, 3.0 g of defoamer, 0.5 g of peptone, and 1000 mL of distilled water. pH3.0~5.0, autoclave at 110~130℃. The yeast extract is yeast extract powder.

[0022] Application example

[0023] Select the market conventional species of ornamental fish red swordfish as the test material, use "Shishenhong" bait (purchased from Haifeng Feed Co., Ltd.) as the basic bait, add the color-enhancing feed additive obtained above at a ratio of 1‰ of the ornamental fish ba...
