1. The nutritional effect of bile acids on crustaceans: Crustaceans (especially shrimp) cannot synthesize cholesterol and bile acids, and they need to ingest cholesterol and bile acids at all stages of growth. The cholesterol and bile acids ingested from the feed are converted into ecdysone in the animal body, which can ensure the normal molting of the crustacean during the growth process. Adding bile acid to shrimp and crab farming can more effectively promote the growth of shrimp and crab.

2. The growth-promoting effect of bile acids on eels: According to the ratio of 6.5 mg per kilogram of eels per day, eels added with bile acids in the feed will increase the weight gain rate by 17% and reduce the feed coefficient by 20%.

3. The growth-promoting effect of bile acid on carp: adding bile acid in the carp feed at a rate of 6 mg per kilogram of fish body weight per day can reduce the carp bait coefficient by 18%.

4. Growth-promoting effect of bile acid on crucian carp: bile acid can significantly reduce the feed coefficient of crucian carp.

5. Growth-promoting effect of bile acid on rainbow trout: bile acid can increase the growth rate of rainbow trout by 60% and reduce the feed coefficient by 45%.

6. The growth-promoting effect of bile acid on channel catfish: bile acid can increase the growth rate of channel catfish and reduce the feed coefficient by 40%.

7. The growth-promoting effect of bile acids on cobia: Bile acids can promote the growth of cobia and reduce the deposition of fat in the body of cobia.

Summary: Bile acids can promote the growth of a variety of aquatic animals, and can improve the body color of fish and increase its market value
