1. Fish seed quality

Putting in the fish requires the same age, the same specification, no injury, complete scale fins, strong traceability, and the Gill cover is not dilated after leaving the water.

two。 Fish seed disinfection

Fish seed disinfection should be paid attention to: ① drugs should be used now, dispensing should use clear water, avoid using fat water, and avoid direct sunlight when medicine is washed. The dose of ② should be accurate to avoid underdose or overdose. ③ soaking time should be appropriate. When fish species are found to be poisoned, water should be added immediately or the fish species should be transferred to another clear water container.

3. Stocking time

Before the fish goes into the pond, the cleaning and disinfection of the pond should be done strictly, and the fish can not be released until the medicine has completely disappeared. The best time for fish stocking is at noon on a continuous sunny day, and when entering the pond, it should be noted that the temperature difference between the water temperature of the fish fry container and that of the pond is less than 3 ℃. Generally speaking, fish species can be transported with oxygen in plastic bags. When going down to the pond, it is necessary to go through "slow seedling" treatment and count accurately.

4. Mixed culture type

Generally, five or six kinds of fish can be mixed in adult ponds, of which one or two kinds of fish are mainly called @ # @ 233 carp. For example, ponds dominated by grass carp are usually equipped with carp and carp; ponds dominated by herring are usually equipped with carp; except for ponds dominated by silver carp and bighead carp, other types of ponds can generally be mixed with silver carp and bighead carp. Silver carp and bighead carp are necessary in mixed ponds.

5. Mixed culture ratio

The "80 ∶ 20" model is now widely used in various places, in which 80 per cent consists of a popular "high-value fish" that eats pellet bait, while the remaining 20 per cent consists of "service" fish, such as filter-feeding fish (conducive to water purification) and carnivorous fish (conducive to the control of wild miscellaneous fish).
