Efficient ecological crab breeding method

Abstract

The invention discloses an efficient ecological crab breeding method and belongs to the field of aquaculture. The efficient ecological crab breeding method includes digging a crab pond, laying 5-10cm thick silt at the bed of the pond, and setting up an anti-escape net around the crab pond; cleaning the pond in winter, and scattering 120-160kg of quick slim per acre; transplanting waterweeds in the pond in February to March in the next year, applying 20-30kg of organic fertilizer per acre, putting in crab seeds for breeding, keeping the water temperature at 5-10 DEG C for the crab seeds, and putting in crucian summerlings at the same time; putting in 300-500kg of snail per acre from April to July, putting in 70-80 silver carp summerlings per acre on June to July, and applying phycomycetes fertilizer on July to August while enhancing fertilizer management to prevent disease damage. The crucian and the silver carp are intercropped with the crab, water environment is improved by the aid of the snail and the waterweeds, reasonable fertilizer management is performed, and accordingly large-weight river crabs can be cultivated efficiently. In addition, the intercropping increases breeding benefit.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular designing a highly efficient ecological crab breeding method. Background technique [0002] At present, the crab breeding technology has been gradually matured under people's exploration, but most of the crab farming is still a single culture mode, and it is difficult to maximize the economic benefits only for river crabs. However, at present, there is still a lack of successful technical experience and guidance for nest breeding and ecological breeding. The environment of traditional crab ponds is not necessarily suitable for the growth of other species. In addition, a reasonable and efficient food chain needs to be prepared to meet the coexistence of different species in crab ponds. Mixed crab ponds The raising model has been in the exploratory stage. Contents of the invention [0003] Purpose of the invention: the purpose of this invention is to provide a kind of efficient ecologica...
