Outer side island reef sea area three-dimensional columnar fixed shellfish cultivation increasing device

Abstract

The invention belongs to the field of marine shellfish culture, and relates to an outer side island reef sea area three-dimensional columnar fixed shellfish culture increasing device which comprises a mooring rope and further comprises a plurality of columnar culture bodies and anchor piles, each columnar culture body comprises a connecting pipe, a balancing weight, a large floating ball and a shellfish attachment assembly, and the connecting rope is arranged in the connecting pipe; a guide pipe is arranged on the outer wall of the connecting pipe, a plurality of guide rings are arranged on the outer wall of the guide pipe, a connecting ring is arranged at the top of the balancing weight, a plurality of through holes are formed in the outer wall of the balancing weight, a plurality of shellfish attachment assemblies are arranged, small floating balls are arranged at the bottoms of the shellfish attachment assemblies, and the connecting pipe is vertically fixed to the balancing weight. The large floating ball is located above the connecting pipe and fixedly connected with the other end of the connecting rope, and the mooring rope and the anchor pile are matched to fix the whole device in a deep sea water area. According to the method, the deep-sea water area culture area around the island reef sea area on the outer side can be utilized to the maximum extent, and the good wind wave resistance is achieved.

Description

technical field [0001] The invention relates to the field of marine shellfish cultivation, in particular to a three-dimensional columnar fixed shellfish breeding device in the sea area of ​​outer islands and reefs. Background technique [0002] In recent years, the overall environmental quality of coastal waters across the country has improved. In 2019, the proportion of coastal waters with good water quality reached 76.6%, an increase of 12.9 percentage points over 2012. However, land-based pollution sources such as industrial, agricultural and domestic wastewater discharges in coastal areas continue to have a great impact on the marine ecological environment. Marine pollution sources such as mariculture, ports, and ship navigation cannot be ignored. The improvement of water quality in coastal waters has not yet been achieved. In 2019, 11.7% of the coastal water quality areas were inferior to Grade IV. [0003] The mariculture industry not only undertakes the important tas...
