Description

Automatic net device that plays of pond culture river crab

Technical Field

The utility model relates to a fishery breeding technology field particularly, relates to an automatic net hauling device for pond culture river crabs.

Background

River crabs, known as Chinese mitten crabs, are one of the crabs with higher economic value. The river crabs have the life habit of digging soil to steal holes, so that the recapture rate of the river crabs is low in the process of capturing the river crabs by draining water, and more river crabs are hidden in soil of the substrate. In winter and spring, river crabs can become egg-carrying crabs after mating and laying eggs. The egg-carrying crabs are parents of the hatching fries of the river crabs, and the acquisition of enough river crab parents is an important requirement for ensuring the hatching quantity of the fries. At present, the method for catching the crab with eggs is a manual catching method after water is drained, so that the recapture rate of the crab with eggs is low. Meanwhile, in the process of catching the egg-carrying crabs in the holes, the egg-carrying crabs can cut off limbs by self, so that the egg-carrying crabs are greatly damaged, the egg-carrying crabs can be dead, and the number of parent eggs of the egg-carrying crabs is lost. Aiming at the defects of low recapture rate and river crab damage in the process of capturing the river crabs at the present stage, the automatic net lifting device for the river crabs is specially designed. The device can effectively avoid the defects of low river crab recapture rate and crab damage caused by egg-carrying crabs, and is time-saving and labor-saving by combining with automatic related equipment.
