Embodiment Construction

[0017] The preferred technical solution of the present invention will be described in detail below.

[0018] High-density crab seedling culture method of the present invention, comprises the following steps:

[0019] 1) Pond desilting and pest removal: Thoroughly remove the silt in the pond one month before the seedlings are released, and then spray 150 catties / mu of disinfectant to remove harmful organisms, predatory organisms and pathogenic organisms, and then remove larger ponds. Separated by every 10 acres of water surface;

[0020] 2) Fertilizer and water: 7 days to 10 days before the seedlings are released, after the toxicity of the disinfectant disappears, use a 60-mesh silk screen to filter the water 10 cm to 20 cm, and then fertilize the water ointment 10 kg / 10 2 days to 3 days before the seedlings are released. Mu, or apply nitrogen fertilizer 20 mg / L, or apply fermented organic fertilizers such as chicken manure to cultivate basic bait, so that the pool wa...

Abstract

The invention discloses a high-density crab seed breeding method which includes the following steps that firstly, vermin killing and desilting of a pond are achieved; secondly, water is enriched; thirdly, crab seeds are cast into the pond; fourthly, the crab seeds are bred; fifthly, daily management is achieved; sixthly, the crab seeds are taken out of the pond. According to the high-density crab seed breeding method, the quality and nutrition of a water body are improved through the scientific method and the scientific steps so as to adapt to high-density crab seed breeding, and high benefits are obtained with low cost.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating high-density crab seedlings. Background technique [0002] It usually takes about 4 months to raise crab seedlings from megalopa, which is often called Haizi, to pond culture. Because megalopa are small and have high requirements for water quality and breeding, the general breeding density is not high. High to increase the survival rate. However, the demand for crab seedlings in the market is still relatively large. Only by realizing high-density breeding can the cost be reduced and the efficiency improved. So it is imperative to propose a high-density crab seedling breeding method. Contents of the invention [0003] The technical problem to be solved by the invention is that the existing crab seedlings have a relatively low breeding density. [0004] In order to solve the problems of the technologies described above, the invention prov...
