Control methods of common diseases of abalone

Abalone taste delicious, high nutritional value, is a valuable marine food, known as marine soft gold, the market price is high. Now, with the progress of artificial culture technology, its culture area and density are gradually expanding, accompanied by a variety of diseases, endangering the growth of abalone and affecting the economic benefits of farmers. The following pro-agricultural network brings you prevention and control methods of common diseases of abalone.

1. Bubble disease

Abalone is easy to get bubble disease in the environment of strong light, poor flow and too little dissolved oxygen. when the disease occurs, the whole province of abalone is full of bubbles, and with the passage of time, the bubbles become larger, and finally make the abalone float on the water, which is mainly harmful to the young abalone.

Prevention and treatment methods: strengthen water quality management, pay attention to light intensity, feed fresh bait, strictly forbid feeding rotten or deteriorated bait, remove residual bait, replace fresh bait, change water in time, and generally remove the disease within 1-2.

2. Swelling disease

Swelling disease is also a digestive system disease caused by water quality and bait. when the disease occurs, the abalone has a poor appetite, but it can not be seen on the outside. The diseased abalone can be seen that the fluid in the outer cavity increases, the color is light red, and the viscera is swollen and protruding. And its adhesion decreased, and died as the disease became serious and gradually lost its vitality.

Prevention and control methods: also strengthen water quality management, forbid feeding rotten or deteriorated bait, fish out the residual bait when the disease occurs, change the water in time, and then feed the oxytetracycline mixed fresh bait, which can be treated in about 2-3 days.

3. Pustulosis

Pustulosis is caused by Vibrio infection. There are small white pustules on abalone feet at the time of onset. After these pustules break, white juice will flow out. With the aggravation of the disease, abalone feet begin to fester, adhesion is poor, food intake decreases, until death.

Prevention and treatment methods: usually should pay attention to disinfection and sterilization, when the disease with oxytetracycline combined with florfenicol mixed bait feeding can be prevented.

4. Calcium deficiency debris

Calcium deficiency debris disease, as the name implies, is abalone lack of calcium, resulting in thin and fragile shell, resulting in shell fragmentation to expose soft tissue, loss of shell protection abalone vulnerable to disease and death.

Prevention and treatment: since the lack of calcium, it is necessary to supplement calcium, can be used in the water weight to add calcium chloride, which can play the effect of calcium supplement.

5. Gifted women with disease

Female disease is a kind of parasitic disease, which is a kind of borehole animal, which will break the shell of abalone, thus corrode the shell of abalone, destroy the protection mechanism of abalone, and is prone to disease, so that abalone can not grow normally until death.

Prevention and control methods: poor culture environment and management can easily lead to frequent incidence of female disease, so it is necessary to strengthen culture management and scientifically regulate water quality, bait, dissolved oxygen and feeding density in order to effectively prevent female disease.

The above are the prevention and control methods of abalone common diseases brought by the pro-agricultural network. This is the end of the introduction of abalone diseases. I hope it can help you, more farming knowledge, please pay attention to the pro-agricultural network.
