Embodiment 1

[0037] In this embodiment, a kind of ecological breeding method for ecological in-situ restoration of Chinese mitten crab is carried out by mainly planting aquatic plants such as Elodea and microdentate eye vegetables and raising snails and sparingly. The breeding method specifically includes the following step:

[0038] 1. Breeding conditions

[0039] 1. Pond Conditions

[0040]The breeding farm is located in the modern agricultural industrial park in Yangchenghu Town, Suzhou. The crab ponds (10-12)×667㎡ / mouth are rectangular and 1.8m deep. There are 12 ponds in total. Drainage principle There are independent inlet and outlet systems and ecological ditches.

[0041] 2. Water quality and bottom quality

[0042] The water source should be sufficient and pollution-free, meeting the requirements of the Fishery Water Quality Standard (GB 11607). The water quality of river crab ponds should meet the requirements of "Water Quality for Pollution-Free Food Freshwater Aquaculture" ...

Abstract

The invention relates to an ecological aquaculture method of high quality Chinese mitten crabs and belongs to the technical field of aquaculture. The method comprises the steps that a pond is selected, cleaned, prepared and sterilized; from February to March in early spring, aquatic plants are planted, a '2+2' composite aquatic plant planting mode is adopted for aquatic plant planting, waterweed and potamogeton maackianus are used as main plants, and wild celery and hydrilla varticillata are used as auxiliary plants; young crabs are put; when the water temperature of the pond reaches above 10DEG C, feed starts to be put; from May to June, siniperca chuatsi and incubation freshwater shrimps are put into the pond; before the Qingming festival, snails start to be put into the pond; during daily management, the change of the water quality is observed, the water quality is adjusted, facilities are overhauled, and pests are removed in good time. According to the method, the aquaculture yield and specification of adult crabs are decided through the reasonable aquaculture density and breeding specification. 800 crabs are bred per mu, about 600 adult crabs are harvested per mu, the large-scale and high-quality brand crabs are bred through a '863' mode with output value of 30,000 yuan pre mu, and the method is an ecological aquaculture mode worthy of copying and popularization.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to an ecological breeding method for Chinese mitten crabs. More specifically, the invention relates to a method of using mainly aquatic plants such as Elodea and microdentate eye vegetables and throwing snails. The mode of raising Chinese mitten crab ecological in-situ restoration culture method, that is, the "863" high-efficiency and healthy ecological breeding method of Chinese mitten crab "Noah No. 1", the method of the present invention can promote the quality and increase of Chinese mitten crab, And effectively guarantee good water quality. Background technique [0002] Chinese mitten crab (Eriocheir sinensis), also known as river crab and crab, has fresh and tender meat, unique flavor and rich nutrition. It is the economic crab with the highest economic value among freshwater crabs, and it is also one of the traditional valuable aquatic products in China. Due to the difficu...
