Method for constructing ecological island reef type marine pasture

Abstract

The invention discloses a method for constructing an ecological island reef type marine pasture. The method comprises the steps that a semi-closed bay facing offshore island reefs is selected to be the marine pasture with a depth of 10-20 meters; according to a preset marine pasture scale, a plurality of sets of fixed rafts are sunk outside an island reef shore base, each fixed raft is connected with a boom cable, and the tops of the boom cables are tied with buoys; a polyethylene rope is fixed to the island reef shore base above the water surface, a first anchor chain is embedded in an islandframe in advance, a second anchor chain is sunk in a sea floor hard sand substrate, net clothes of more than one layer are connected between the polyethylene rope and the first anchor chain and the second anchor chain to form a net cage, and fishes proliferate in the net cage; seaweed breeding floating rafts are constructed outside the net cage; sea cucumbers are planted at the bottom of the netcage. Compared with the prior art, the method can maintain the maximum economic output while not causing environmental pressure by relying on the advantage of an island reef area.

Description

technical field [0001] The invention relates to the technical field of fishery multiplication, in particular to a method for constructing an ecological island-reef marine pasture. Background technique [0002] Based on the principles of marine ecology and modern marine engineering technology, marine ranching is oriented towards environmental and ecological harmony, and integrates environmental protection, resource conservation, efficient production and recreational fishery. important way. Compared with mariculture, marine ranching pays more attention to environmental protection and quality improvement, which not only reduces environmental pollution, but also improves the quality of cultured organisms; compared with fishing, marine ranching focuses on the conservation and replenishment of biological resources. Marine ranching is now regarded as a new growth point of marine economy in the 21st century. [0003] Based on the construction area, marine ranching can be divided i...

Problems solved by technology

[0004] ① The type of project site selection is single, most of them are concentrated in open sea areas, and the environmental advantages are not fully utilized

The productivity of islands and reefs is more abundant, and the function of avoiding predators provided by organisms is more prominent, but there are currently no marine pastures built around islands and reefs

[0005] ② One-sided pursuit of yield, single multiplication species, failure to select suitable multiplication species according to the environmental biological conditions of the pasture sea area

[0006] ③ Neglecting the ecological function of marine pastures, only focusing on the economic output of pastures, ignoring its ecological restoration function
