Precious marine product aquaculture device suitable for shallow sea

Abstract

The invention belongs to the field of sea farming, and particularly discloses a precious marine product aquaculture device suitable for shallow sea. The device comprises an uncovered cube plastic box (1), two cambered-surface-shaped plastic plates (2 and 3) and a sinking prevention hard plastic plate (4), wherein the cambered-surface-shaped plastic plates (2 and 3) are located below the uncovered cube plastic box, and the sinking prevention hard plastic plate (4) is located on the lower portion. Four steel pipes (5) are fixed to four corners of the uncovered cube plastic box (1), penetrate through the sinking prevention hard plastic plate located on the lower portion and enable the uncovered cube plastic box (1) and the sinking prevention hard plastic plate (4) to be connected into an integrated structure. A steel conical fixing head (6) of a hollow structure is welded to the bottom of each steel pipe (5), and the tip of each fixing head (6) is provided with two rows of round holes (7) arraying around a corresponding vertex. The device is simple in structure, greatly improves the survival rate of fry of precious marine products and is beneficial to mass application and popularization.

Description

technical field [0001] The invention belongs to the field of marine cultivation, and specifically refers to a cultivation device for marine treasures. Background technique [0002] At present, sea cucumbers, abalones and other sea treasures are cultivated in large quantities and in many ways, but the most suitable way is bottom-sowing culture in sea areas, and the bottom-sowing culture in sea areas mainly uses artificial reefs placed in sea areas as economic organisms for breeding. the attachment base. The conventional way of arranging artificial reefs is to directly drop stone reefs, cement reefs, etc. on the seabed at fixed points on the sea surface, and then dive into the bottom of the water by divers to place sea treasure seedlings on the artificial reefs. However, due to the heavy weight of the reefs of stone reefs and cement reefs, they will sink in most of the sand and mud bottoms; if lighter materials are used, the artificial reefs will have weak wind and wave resis...

AI Technical Summary

Problems solved by technology

However, due to the heavy weight of the reefs of stone reefs and cement reefs, they will sink in most of the sand and mud bottoms; if lighter materials are used, the artificial reefs will have weak wind and wave resistance in sea areas, and once they encounter currents, they will sink. It will move or collapse due to the impact of running water, and cannot resist the impact of ocean currents. Therefore, it is difficult to solve the problems encountered in the process of breeding marine treasures only by changing the material of artificial reefs.

Another problem to be solved is that when the bottom-sowing culture method is adopted in the sea area, a large number of seedlings of sea treasures will inevitably be washed away by the movement of the sea current, and it is currently impossible to adopt the method of fence and seine in the seabed area to treat these seedlings. Sea treasure seedlings are kept in captivity, so the economic benefits are often severely damaged
