Deepwater raft shellfish culture method

Abstract

The invention relates to a shellfish culture method, and especially relates to a deepwater raft shellfish culture method; a culture breed stocking water layer is determined according to culturing shellfish biological habit, culture environment water temperature and stability, baits and harmful organisms; the raft is arranged in the water zone of 30-60m in depth, peg cables are connected with a raft body, two ends are fixed in seabed, the whole raft body is pressed in seabed by a plurality of weights at intervals, the raft body is provided with float sample buoyancy, one end of the shellfish culture cage is hung on the raft body through a lifting rope, the other end of the cage is bonded with a buoyancy through a floating rope, and the length of the lifting rope is 0.6-1.2m. The method provides the shellfish culture novel mode, fully utilizes water temperature difference advantages of the deepwater under 16m, thus providing a stable water quality water temperature environment for the shellfish, improving seedling intermediate breeding survival rate and seedling cultivating speed, solving living through summer problems of existing shellfish culture technology, fully utilizing marine site resources, and forming active promotion effect for shellfish industry upgrading.

Description

technical field [0001] The invention relates to a shellfish culture method, in particular to a deep-water platform raft shellfish culture method. Background technique [0002] At present, in my country's coastal areas, shellfish farming has developed rapidly, and has become a key breeding industry in the Liaodong Peninsula in northern my country, Shandong Changdao and other sea areas. The shellfish farming methods mainly adopt two methods: bottom-seeding multiplication (release multiplication) and floating raft culture. . Bottom-seeding multiplication method guarantees the natural growth of organisms in the natural environment. As a healthy breeding model, it makes full use of the self-purification ability of seawater to ensure the safety and quality of cultured organisms, and has the advantages of less impact on natural environment changes such as wind and waves. Not all places are suitable. The water temperature must be suitable, and the bottom of the sea is mostly mud-san...

Bottom-seeding multiplication method guarantees the natural growth of organisms in the natural environment. As a healthy breeding model, it makes full use of the self-purification ability of seawater to ensure the safety and quality of cultured organisms, and has the advantages of less impact on natural environment changes such as wind and waves. Not all places are suitable. The water temperature must be suitable, and the bottom of the sea is mostly mud-sand or sand-mixed areas such as rocky reefs and sandstone bottoms. Sea areas such as soft mud bottoms cannot be used for bottom seeding and multiplication.
