Problems solved by technology

[0003] At present, the shrimp and crab breeding waters require that the planting area of ​​aquatic plants accounts for about 50% of the water surface, and 200-500 kg of snails are put in per mu, but there are many defects. At the end of the month, the snails and mussels are basically ingested. During the high temperature period, the self-purification function of the shrimp and crab culture water body is weakened or lost. Therefore, the present invention proposes a repair and purification method in a shrimp and crab culture pond that can solve the above problems.

Embodiment 3

[0028] 1) Renovation of breeding ponds: Select rectangular breeding ponds with sufficient water sources, convenient drainage and irrigation, and no pollution, stock shrimp and crabs in the breeding ponds and plant rice, and feed them regularly. The rice is selected as a one-season rice variety that has a long growth period and is resistant to diseases and insects. The planting density is 20cm×30cm; during the growth of rice, manual weeding is used; the middle part of the culture pond is provided with a partition ridge, the two ends of the partition ridge are connected with the wall of the culture pond, and baffles are set on both sides of the partition ridge, so that shrimp and crabs cannot Holes are drilled on the separation ridge, and water inlets and water outlets are arranged on the separation ridge; fences are arranged around the breeding pond.

Abstract

The invention discloses a repair and purification method in a shrimp and crab breeding pond. The repair and purification method comprises the following steps of (1) reconstruction of the breeding pond, (2) constructing of a purification area and (3) arranging of an aeration circulation system. Inorganic salts, ingest residual feed of paladina and bivalves and other organic matters are absorbed anddigested by using water plants through the purification zone, pollutants are converted into nutrient sources of aquatic plants, paladina and bivalves, then circulating pumps and aerators are arrangedto cyclic purify a water body to improve the dissolved oxygen condition of the bottom of the water body, and therefore the self-purification ability of the breeding water body is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture environment purification, in particular to a method for repairing and purifying shrimp and crab culture ponds. Background technique [0002] In recent years, the aquaculture industry of famous and high-quality aquatic products such as shrimp and crab has developed rapidly, and the amount of feed has also doubled accordingly, and the pollution of water quality has also become increasingly serious. Now the water environment of shrimp and crab aquaculture is purified and restored mainly by planting aquatic plants and Put in snails and other measures for purification. [0003] At present, the shrimp and crab breeding waters require that the planting area of ​​aquatic plants accounts for about 50% of the water surface, and 200-500 kg of snails are put in per mu, but there are many defects. At the end of the month, the snails and mussels are basically eaten up. During the high temperature period, t...
