Abstract

The invention relates to a method for catching scylla paramamosian from a polyculture pond. A special net tool is made to capture the scylla paramamosian from the polyculture pond, other living beings cultivated in a mixed mode are placed back, and a plurality of groups of net tools can be utilized simultaneously to capture the scylla paramamosian according to the requirements. The open type net tool is adopted to capture the scylla paramamosian, baits are utilized to lure the scylla paramamosian to enter the net tool, the scylla paramamosian can be effectively caught from the polyculture pond, particularly from a shrimp and crab polyculture pond, other varieties cultivated in the mixed mode can be placed back, the scylla paramamosian of different specifications can be selected and caught according to the requirements, loss caused by mutual slaughter of the crabs can be avoided, cultivation efficiency is improved, and a device is reasonable and simple in structure, low in cost, convenient to operate and high in practicality.

Description

technical field [0001] The invention belongs to the technical field of crab breeding, in particular to a method for catching blue crabs from polyculture ponds. Background technique [0002] Scylla paramamosain belongs to Arthropoda, Crustacea, Decapoda, Portunidae, and Scylla. It is mainly distributed in the Yangtze River Estuary and beyond in my country. The south coastal waters are my country's important marine fishery resources and seawater cultured crabs.
