Fish is the main aquaculture project in China. How to improve the utilization rate of bait in fish farming?

1. shaping natural bait in the process of breeding, shaping natural bait is a very important work plan. When we are breeding, we should improve the water quality of the pond and increase the total number of zooplankton in the pond according to the work of the water body. This kind of zooplankton can be used as bait for fish, and fish like it very much. Appropriate popularization of natural bait can not only improve the conversion rate of bait reasonably. It can also reduce the capital investment of bait, indirectly reduce the cost of bait and improve the economic benefits of breeding. However, when shaping natural bait, attention should be paid to controlling the total amount to avoid the decrease of dissolved oxygen caused by excessive total amount and endangering the growth and development of fish.

2. There are a lot of people living in the bottom, such as grass carp, if we are all cultivating middle-and upper-level fish such as carp. In this way, the bottom fish crucian carp can be properly matched, and sufficient bait can be provided for the bottom fish when the bait not eaten or missed by crucian carp sinks to the bottom of the pool. That will not only ensure that carp have enough ingredients, but also increase the income of bottom fish with the same bait. The utilization rate of bait will definitely be improved, and the residual bait environment can also be avoided from polluting the water body and endangering the growth and development of fish.

3. Pay attention to the specified timing and quantity when effectively feeding bait, so that fish can develop better eating habits. When feeding, you must not change the feeding address casually, otherwise some fish will not be able to eat at all. Then it is necessary to control the feeding amount and adjust the feeding amount within the effective range to ensure that every fish can eat enough and avoid excessive feeding. The quality change of residual bait will not only destroy the water body, but also continue to have a serious impact on the growth and development of fish if eaten by mistake, so we must pay more attention to it.

4, pond oxygenation Many fish farmers often ignore the dissolved oxygen in the water, especially in the area where the bait is fed. At least 70% dissolved oxygen is not enough now. If the dissolved oxygen is not enough, it is useless to feed the best bait. If the dissolved oxygen in the pond is less than 3 mg per liter, the fish will stop eating. At least 5mg can make the fish eat normally. Therefore, it is necessary to ensure that the dissolved oxygen in the water quality is above 5mg when breeding, and add oxygen-increasing equipment in the breeding area to make oxygen immediately.
