Reservoir fish farming generally chooses silver carp, bighead carp, grass carp, carp, crucian carp, etc., fast growth, high yield, strong disease resistance, large market demand, high economic value, can make full use of the bait resources in the reservoir, improve the breeding efficiency of the reservoir.
1. Reasonable fertilizer and water.
Generally speaking, fish farming in reservoirs is mainly based on natural bait, such as phytoplankton, zooplankton, etc. There are more natural bait in the fertilizer water, the water quality is stable, suitable for the growth and development of fish, we can promote the growth of fish and improve the breeding efficiency through reasonable fertilizer water. Many breeding friends are using: silver carp fast growth pioneer + em bacteria pioneer + diatom pioneer, rich in nutrients, can quickly fertilizer hydroponic algae to cultivate rotifers, long-lasting fertilizer effect, green environmental protection, more than 25 can be replaced with chlorella diatoms, improve the number of plankton in the water body.
2. Determine stocking densities.
Stocking density is one of the key factors in reservoir fish farming. If the stocking density is too high, it will lead to overbreeding of fish, competing for bait and living space, and affecting the growth and production of fish;If the stocking density is too low, the bait resources of the reservoir cannot be fully utilized, which affects the breeding efficiency. Therefore, according to the size, shape, water depth, water quality and other factors of the reservoir, you can put 400 pieces per mu in the case of early ponding, and it is best to put about 300 pieces if you want to get out of the pond about 10 catties to prevent affecting the breeding efficiency.
3. Strengthen water quality management.
If the water quality is not good, it will affect the growth and production of fish, and even cause diseases. Therefore, it is necessary to strengthen water quality management, prevent the use of toxic and harmful fertilizer and water products, and prevent excessive fertilizer water from causing water quality to deteriorate. Generally speaking, in order to maintain the freshness, sufficient oxygen and appropriate pH of the water quality, the water fertility can be kept stable and the water quality can be improved, and the water quality can be improved through the self-regulation of the water body.
