Causes of Liver Disease in Shrimp and Key Prevention and Treatment Techniques
Causes of Liver Disease in Shrimp and Key Prevention and Treatment Techniques
(Agricultural Wealth Network) Since entering June, as shrimp farming enters the middle and late stages, various harmful substances and organic matter in the pond also increase. The shrimp's liver bears a relatively large detoxification task, decomposing and metabolizing various toxic substances. Coupled with the invasion of some harmful bacteria, problems in the shrimp's liver are unavoidable, such as fatty liver, enlarged liver, whitened liver, red and swollen liver, atrophied liver, and liver erosion. If prevention and treatment are not carried out as early as possible, once other diseases occur concurrently, the losses are often severe. Through several years of clinical research, we have been able to control shrimp liver disease quite well. The relevant knowledge is introduced below.
1. Basic knowledge about the shrimp liver
The shrimp's liver is located above the stomach, divided into left and right lobes attached to the top of the stomach. Under normal conditions, its color is yellow-brown, plump and elastic.
2. Manifestations of abnormal liver
It appears cloudy white, with branching black pigment distributed on it, or appears light red, red, or black, enlarged or atrophied and eroded, with relatively soft tissue and a lack of elasticity. When liver cells are examined under a microscope, the cells can be seen to be unevenly arranged and of varying sizes, with most cells showing fatty degeneration.
3. Causes of liver disease
Shrimp are more prone to liver disease after 30 days, mainly because in the middle and late stages of farming the water environment deteriorates, toxic substances in the water increase, and some drugs harmful to the liver added to the feed increase the burden on the liver. At this time, some bacteria seize the opportunity to invade, causing pathological changes in the liver. In the early stage of the disease, the shrimp's feeding and activity are relatively normal, but growth is very slow and they do not molt for a long time. Once other diseases occur concurrently, the losses are often severe.
4. Key prevention and treatment techniques for liver disease
Because many drugs must be decomposed and metabolized through the liver, drugs must be chosen with great care when treating liver disease. In addition, the liver has a relatively high demand for B and C group vitamins, so these should be supplemented.
(1) Prevention methods for liver disease: Regularly sprinkle Detoxification and Anti-Stress Essence Liquid to reduce damage to the liver from toxic substances such as heavy metal ions, algal toxins and bacterial toxins. Persist every month in feeding Jinfang Liver Protection Treasure and Jinwei'an mixed into the feed for internal consumption, with each continuous feeding lasting 7-10 days, to reduce the burden on the liver.
(2) Treatment methods for liver disease: Soak Jinwei'an (6 mu-meters per bag) in water for 2 hours, then dilute with water and splash over the whole pond to supplement amino multivitamins in the water body and inhibit waterborne pathogens. On the second day, dilute Yangshui Ecological Treasure and splash it over the whole pond to decompose toxic substances in the water; at the same time, combine with internal feeding of Jinfang Liver Protection Treasure + Wei Mian + Multi-Effect Antivirus + Pule, continuously mixing into feed and feeding for 3-5 days, which can eliminate some symptoms of the liver and restore the shrimp body to normal. In addition, for some shrimp fry with liver problems, Jinfang Liver Protection Treasure (2 mu-meters per bag) can be used directly once a day, splashed for two consecutive days.
In summary, the liver is an important detoxification organ of the shrimp body, so attention must be paid to the prevention of shrimp liver disease. It is recommended to detoxify the water body once a month, and at the same time persist in using microecological preparations such as Yangshui Ecological Treasure, Nitrifying No. 1 and Water Protection Probiotics to degrade excess organic matter in the pond water. Regularly adding Jinfang Liver Protection Treasure, Multi-Effect Antivirus, Jinwei'an and others to the feed can effectively help the shrimp body repair damaged liver cells and maintain the health of the shrimp's liver.
