Abstract

The invention discloses a crab seedling collection system of a crab culture pond. The system comprises two strip-shaped buoy plates, a triangular guide plate arranged at the front part of each buoy plate, a front connecting plate arranged between the front pats of the two buoy plates, a rear connecting plate arranged between the rear parts of the two buoy plates, a transverse slide groove arrangedon the upper surface of each buoy plate, a support column connected with each transverse slide groove in a slide manner, a transverse rod arranged at the upper end of each support column, a verticalcylinder arranged on each transverse rod, and a clamping plate structure arranged on a telescopic rod of each vertical cylinder. The clamping plate structures of the two buoy plates are used to clampan Elodea nuttallii strain. The system has the characteristics of high crab seedling collection efficiency, effective reduction of labor intensity, and no influence on the normal growth of Elodea nuttallii.

Description

technical field [0001] The invention relates to the technical field of crab breeding, in particular to a crab seedling collecting system in a crab breeding pond with high collecting efficiency and reduced labor intensity. Background technique [0002] Elodea is usually planted in ponds where crabs are raised. The top of Elodea is usually more than 15 cm above the water surface. Crabs inhabit the lower part of Elodea. For large crabs, in autumn, crabs will automatically climb to the bottom of the pond. On the slope, just catch crabs by the pond; [0003] However, the crab seedlings will not go ashore automatically, and the crab seedlings are also hidden in the lower part of the Elodea. When collecting the crab seedlings, people need to go into the water and shake each Elodea plant to drive out the crab seedlings. The operation is difficult and labor-intensive. The collection efficiency is low. Contents of the invention [0004] The object of the invention of the present i...
