Measures to ensure the supply of fish fry
Function and use
In view of the serious damage to farmed fish fry and the shortage of supply in the disaster area, measures such as strengthening cultivation and collecting parents are put forward to ensure the supply of fry.
Technical measures
1. Statistics understand that the number of seedlings and the production capacity of seedlings are needed to restore production in the region, find out the gap of seedlings, contact the seedling production field as soon as possible, and supplement high-quality and healthy seedlings to resume production.
two。 Pay attention to understand and grasp the market information of parent fish, and do a good job in collecting parent fish.
3. Strengthen the cultivation of parent fish, appropriately increase the feed with high protein content, and feed nutritional immune enhancers such as vitamin C, so as to promote the normal development of parent fish as soon as possible, improve maturity and ensure that the production capacity is not reduced.
4. Strengthen the collection of large-scale fish as parents through various channels, such as reservoirs or deep-water mountain ponds, and strengthen cultivation, so as to restore production of fry systems such as fish fry farms as soon as possible.
5. After the weather warms up, the water level of culture can be lowered appropriately to accelerate the rise of water temperature and promote the gonadal development of parent fish.

Prevention and treatment of common bacterial diseases in fish
1. The cause of hemorrhagic disease is the deterioration of water quality at the bottom of fish pond, low dissolved oxygen, many harmful substances, poor management of culture, or feeding moldy and inferior bait, which will cause the disease. Prevention and control methods to strengthen feeding and management, comprehensive prevention. If drugs are used regularly, dibromohydantoin, bromochlorohydantoin and Chinese herbal extract preparations can be used to disinfect the water; or beneficial bacteria such as photosynthetic bacteria can be used to purify water quality; immune enhancers can be added to the diet to absorb and degrade ammonia, nitrogen, nitrite and other harmful substances in water by using zeolite powder and nitrite degradants.
