Many farmers have the habit of using fish ponds in adult fish ponds. Indeed, under the condition of not affecting the adult fish production, large-scale high-quality fish species can be provided for the adult fish production in the next year through nesting of summer fish fry. On the one hand, it can save some funds and reduce the cost of breeding; on the other hand, it can avoid fisheries casualties caused by fishing or transportation, or affect the production due to the lack of a suitable fish species. It is indeed a good method to kill birds with one stone. However, if you really want to make a successful fish pond culture, you must pay attention to the following issues:
When the adult fish species are stocked, they need to make room for the next step to raise the fish fry and use the adult fish ponds to raise summer fish and fry, etc. The adult fish species should not reach the limit when they are stocked, and should leave room for the next nesting work. Failure to do so may affect the growth of nested fry, or may be dangerous due to excessive fish on the pond.
Encourage cultivation of summer carp seedlings in order to meet the demand specifications for adult fish culture in adult ponds, it must be put in as soon as possible, generally in early July. This fish into the pond early, long growth period, bred large specifications.
Accurately determine the stocking rate of nesting fry
The size of the out-of-stock fish ponds has a certain relationship with stocking time, fry quality, and feeding management, but has a greater relationship with stocking density. It can be said that under the condition of stocking time and the specification of the fry, the size of the breeding scale depends on the stocking density. Therefore, reasonable stocking densities should be determined based on technical conditions and management levels.
Strengthen the management of fish culture in adult fish ponds. Individuals of pond fish have large or small fishes. Therefore, attention should be paid to the management of adult fish and fish fry. Adhere to the "time, orientation, qualitative, quantitative" principle of feeding, according to the weather, fish eating and activities and other flexible control of the amount of bait, see the water fertilization training fish natural food palatability, while paying attention to tour pond, water quality management, disease prevention .
Pay attention to the collocation
In summer ponds, nestlings of summer fry and other fish are raised, and the same or similar diet fry can not be stocked in the same pool. Set the ratio of cockroaches and cod fish fry to 4:1 to 5:1, and it is best to keep or put the fry in the carp pond. The structure and quantity of stocked fry can not be completely copied in accordance with the structure and quantity required for adult fish breeding.
Adult fish caught in time out of the pond
In fish ponds, the amount of fish on ponds gradually increases with the passage of time, and sudden changes in the weather during the hot season tend to occur. After August, adult fish have reached commercial specifications one after another. In this way, the adult fish should be caught and listed in a timely manner. On the one hand, the contradiction between large amounts of fish on the pond can be alleviated to avoid accidents; on the other hand, time and space can be gained for fry growth. Improve the quality of fingerlings.
