After the frost falls, pay attention to water mold disease, gill bleeding, ringworms and melon worms

<b>First, focus on diseases</b>

1, water mold disease: freshwater aquaculture fish can occur, the prevalence of water temperature 10 °C ~ 20 °C, all breeding areas need to do a good job of prevention.

2. Infectious hematopoietic organ necrosis: the main object is rainbow trout, the water temperature of the disease is 8 °C ~ 15 °C, and the younger the fish age, the more sensitive the disease.

3. "Gill bleeding" disease: the main object is crucian carp, and the water temperature of the disease is 15 °C ~ 25 °C.

4. Ringworm disease: it mainly endangers grass carp, silver carp, bighead carp, carp, eel and other fish, especially fish species are the most susceptible to infection.

5, small melon worm disease: small melon insect breeding suitable water temperature 15 °C ~ 25 °C, a variety of freshwater fish, migratory fish and ornamental fish can be infected, especially in fish species susceptible.

<b>2. Prevention and control measures</b>

1. Pay attention to water quality control. Regularly use quicklime or chlorine disinfectants to disinfect aquaculture water bodies, and regularly use substrate modifiers or microecological preparations to improve the growth environment.

2. Scientific and reasonable feeding. Reasonable feeding of high-quality feed, multivitamins and immunogly polysaccharides can be added to the feed.

3. Strengthen production management. Pay close attention to weather changes, patrol the pond in time, open the aerator in a timely manner, and fish and market in time after reaching the specifications.
