A kind of shallow sea sea cucumber trap

Abstract

The invention belongs to the field of sea cucumber harvesting, in particular to a shallow sea sea cucumber trap, the top and bottom of the box body are open structures, one end of the shelter board is hinged to the top of the box body, the other end is an open end, the box body There is a separation screen at the bottom; one side of the box is equipped with a mesh valve for sea cucumbers to enter, and the opposite side is equipped with a food attractant delivery grid, and the box is equipped with a crawling board and a hard sieve board, and the crawling board It is fixedly connected with the box, one end of the hard sieve plate is hinged on the crawling plate or the food attractant delivery grid, and the other end is a free end, and a spring support rod is arranged between the lower surface of the hard sieve plate and the food attractant delivery grid ; The crawling plate and the hard sieve plate divide the inside of the box into a lure area and a collection area; a counterweight is installed on the box. The invention maximizes the trapping efficiency without considering whether the water quality is turbid or not, and without resorting to divers.

Description

technical field [0001] The invention belongs to the field of sea cucumber harvesting, in particular to a shallow sea sea cucumber trap. Background technique [0002] As one of the eight treasures of the sea, sea cucumber is the species with the highest output value of a single species in my country's mariculture objects. At present, the sea cucumber aquaculture industry has become a key pillar industry in mariculture, and shallow sea aquaculture is one of the main breeding methods for sea cucumbers. The output However, sea cucumbers can only be harvested by diving at present, lacking other effective special harvesting facilities and methods. Affected by environmental factors such as weather and sea conditions, divers often face certain dangers when fishing in deep-water breeding areas above 10 meters. These uncertain factors greatly restrict fishing work and reduce fishing efficiency. At the same time, in the process of diving and harvesting, the bottom of the water is often ...

[0002] As one of the eight treasures of the sea, sea cucumber is the species with the highest output value of a single species in my country's mariculture objects. At present, the sea cucumber aquaculture industry has become a key pillar industry in mariculture, and shallow sea aquaculture is one of the main breeding methods for sea cucumbers. The output However, sea cucumbers can only be harvested by diving at present, lacking other effective special harvesting facilities and methods. Affected by environmental factors such as weather and sea conditions, divers often face certain dangers when harvesting in deep-water breeding areas above 10 meters. These uncertain factors greatly restrict the harvesting work and reduce the harvesting efficiency.

At the same time, in the process of diving and harvesting, the bottom of the sea cucumber is often muddy due to the harvesting of sea cucumbers, which affects the subsequent harvesting efficiency of sea cucumbers.
