Carp has strong adaptability, can grow well in the range of water temperature 15-30℃, and is cold-resistant, anoxic and salt-tolerant. Carp is an omnivorous fish, which has a wide range of feeding habits. It can be fed with compound feed in the whole process of pond feeding, and its growth rate is fast. Carp is one of the most widely cultivated freshwater fish species in the world, accounting for 8-9% of the total aquaculture output. At present, more than two thirds of the world's farmed carp are produced in China. According to statistics, the carp output in China in 20 1 1 year is 27 1.82 million tons, 2,897,000 tons in 20 12 years and 3,022,500 tons in 20 13 years, showing a continuous growth trend.
Adding bile acid to carp feed can prevent fatty liver and relieve acute gill rot of carp. Adding bile acid to feed can significantly reduce the activity of serum aspartate aminotransferase (AST) in carp, which indicates that bile acid can repair liver damage. When aquatic animals have bacterial diseases, they will use antibiotics to prevent and treat the diseases. After the bacteria are killed by antibiotics, they will produce a lot of endotoxin, which can cause liver damage.
