Moveable bottom-raft type cultivation system

Abstract

A movable bottom raft culture system consists of a main rope, a floating ball string, an anchor rope, a culture cage, balancing weights, an iron anchor, a fixed floating ball and a mark floating ball which are interconnected. One end of the anchor rope is connected with the main rope, and the other end is connected with the iron anchor; the floating ball string is evenly tied to the main rope; two ends of the main rope are respectively provided with a balancing weight; the fixed floating ball and a fixed floating ball connection rope are arranged at proper positions of the anchor rope; the culture cage and the mark floating ball are also tied to the main rope. The system adopts a bottom culture mode, which is favorable for improving wind and wave resistance of the raft culture system in stormy weather and can develop a bottom culture sea area. The system has the advantages of convenient operation, integral movement and long service life, is convenient for wide popularization and is an ideal benthos culture device.

Description

technical field [0001] The invention relates to a movable submerged raft culture system, which belongs to the field of aquaculture enhancement 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 areas have...

Problems solved by technology

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 areas have strong waves and rapid currents, it is not easy to set up raft farming equipment, so it is urgent to carry out wind and wave resistance for raft farming facilities in waters with high sea conditions Technical research, expanding new breeding space, meeting the major demands for the healthy and sustainable development of marine fisheries
