Controllable aqueous layer raft type cultivation system

Abstract

A raft culture system capable of controlling a water layer consists of a boom rope, a balance floating ball string, an anchor rope, a fixed floating ball, a water layer regulation floating ball, a depth regulation rope, a balancing weight, a stake anchor and the like. The boom rope is provided with the balance floating ball string and the depth regulation rope; the water layer regulation floating ball is tied to the upper end of the depth regulation rope, and the balancing weight is tied to the lower end of the depth regulation rope; the culture water layer is controlled by controlling the length of the depth regulation rope; submergence of the boom rope is favorable for improving wind and wave resistance of the raft system in stormy weather and adapted to requirements of different cultured objects for the culture water layer. The system has simple machining process, convenient operation, long service life, is favorable for wide popularization and is adapted to the requirements for moving the raft facility culture offshore.

Description

technical field [0001] The invention relates to a controllable water layer raft culture system, which belongs to the field of aquatic product breeding equipment. Background technique [0002] Raft aquaculture has made an important contribution to my country's mariculture and is one of the main methods of mariculture in my country. Although the scale of raft farming in my country ranks first in the world, the types of farming involve algae (kelp, seaweed, asparagus, Eucheuma, agaric, hijiki), shellfish (scallops, oysters, mussels), abalone, ginseng, etc. Sea urchins, crabs and other dozens of species, the aquaculture production accounts for more than half of the total domestic mariculture production, and the per unit yield has reached a relatively high level. However, most of my country's mariculture activities are currently concentrated in the near-shore -15-meter isobath. The waters between -15 and -40m isobaths still need to be vigorously developed, but because these sea ar...
