In recent years, with the continuous expansion of the breeding scale of California sea bass, the breeding density is also increasing. However, due to the special living and feeding habits of California perch itself, and the relative lack of research on the nutritional requirements, digestion and absorption, and metabolic mechanisms of California perch, there have been hepatobiliary diseases such as fatty liver and hepatobiliary syndrome, which have restricted Development of the California perch farming industry.
Why is California perch so prone to liver and gallbladder disease?
1. California perch is a patient with congenital fatty liver. After a period of time in breeding, the incidence of hepatobiliary disease is almost 100%.
2. Long-term feeding of low-quality feed or chilled food with bacteria, the toxins will cause greater damage to the liver, which will cause metabolic disorders in California sea bass, leading to liver disease.
3. Excessive feeding. Due to the high price of the head fish, the farmers are eager to go out of the pond and increase the feeding. This will undoubtedly increase the burden on the digestive organs such as the liver and gallbladder of the California sea bass, resulting in indigestion and excessive burden on the liver. Mortality of California perch developing hepatobiliary lesions.
4. Indiscriminate use of drugs, frequent use of disinfectants and antibiotics with strong effects, high residues, and strong irritating fish medicines.
How to reduce the occurrence of hepatobiliary disease in California perch?
Because of the nature of the liver itself, it will cause damage to the liver unconsciously during the breeding process, so we must pay attention to the protection of the liver.
First of all, in the selection of feed, it is necessary to choose a manufacturer with reliable quality, stability and good reputation. Secondly, remember to add drugs to the feed at low doses and for a long time, supplement vitamins and trace elements in time to improve the nutritional and metabolic status of the fish, and do not blindly pursue benefits and increase the breeding density during the breeding process. Bile acids that protect the liver and gallbladder protect the liver.
As an endogenous active substance in fish, bile acid can regulate fat metabolism, promote fat absorption, transport fat to muscle tissue, reduce fat deposition in the abdomen and hepatopancreas, and reduce the burden on the liver. Promote the secretion and discharge of bile, combined with mycotoxins, heavy metal ions, drug toxins excreted with bile, to protect the liver. Repair liver damage, dredge the biliary tract, and completely and completely solve liver and gallbladder diseases such as fish fatty liver, flower liver, green liver, and yellow liver.
