Urechis unicinctus collecting device

Abstract

The invention discloses an urechis unicinctus collecting device. The device comprises an urechis unicinctus collecting net box (11) with an opening on a bottom surface, a net pocket arranged (9) on one side surface and remaining surfaces covered with mesh cloth, first main pipes (1) are transversely arranged at the lower portions of the opposite side surfaces of the urechis unicinctus collecting net box (11) and the net pocket (9), third main pipes (3) in communication with the first main pipes (1) through first connecting pipes (12) are disposed at the lower portions of the first main pipes (1), and second main pipes (2) disposed in parallel with the third main pipes (3) are communicated with the third main pipes (3) through second connecting pipes (13); a water spraying pipe sprays out the water to wash a sand layer at the bottom of a pool, the impulse is used for making the urechis unicinctus rush out and float upward, and water flows the floating urechis unicinctussea into the netpocket at the back of the collecting device for collection, which reduces the cost, improves collection efficiency, and reduces the rate of urechis unicinctus residual compared with manual dredging.

Description

technical field [0001] The invention relates to the field of industrialized cultivation of the single-ringed weeter, in particular to a collection device for the single-ringed weeter. Background technique [0002] Urechis unicinctus, commonly known as sea intestines, belongs to the phylum Echiurioidea, the class Echiurida, the order Xenop neusta, and the family Urechidae. Distributed in Russia, Japan, North Korea, and the coasts of the Yellow and Bohai Seas of my country, it is a common species of benthic organisms in the intertidal subtidal zone and subtidal shallow water zone of the northern coast of my country. The individual is fat, the meat is delicious, and the body wall is rich in protein, which has high economic value. In recent years, due to the excessive fishing intensity and insufficient resources, the artificial seedling breeding and factory-intensive breeding of C. monoringensis have begun to be paid attention to. Because the single-ringed weetle has the habit...
