Winter seedlings mainly have the following advantages:
1. The water temperature is low, fish activity is weak, metabolism is reduced, scales are tight, easy to catch and transport, reduce mechanical damage, seed generally does not suffocate death, the survival rate is high.
2. When the water temperature is low, the number of various pathogenic microorganisms is small, the fertility is weak, and the probability of occurrence of various diseases is greatly reduced.
3. Winter seedlings can be exempted from seeding and wintering pond operations.
4. Ferocious fish feed intake in the winter or stop feeding, the harm to the seed is small, and when the water temperature rises after the spring begins, the fierce fish begin to feed, the seed has been initially adapted to the water environment, and the ability to evade the enemy is enhanced.
5. The seedlings can be evacuated earlier, adapt to the new environment in advance, and can ingest food after the water temperature rises, accordingly prolonging the growth period, and laying the foundation for wheel catching and seed raising.
6. The water level in winter is low and there is no need to drain water.
7. It is conducive to the arrangement of other breeds, shrimp and crab seedlings and other supporting work.
In addition, winter should be selected when the seedlings sunny, windy weather. The size, size, and size of the seedlings should be consistent and robust and free of parasites. When the water temperature rises at noon on a sunny day, a certain amount of concentrate feed can be used to feed fish and promote the growth of seedlings.
