Single-floating-pipe submersible intensive choice rare seafood cultivation device

Abstract

The invention discloses a single-floating-pipe submersible intensive choice rare seafood cultivation device. The device comprises a floating pipe, cage frames and a depth fixation device, wherein the floating pipe is a sealed single high-density polyethylene pipe, and one end of the floating pipe is provided with a gas aeration and exhaust port and the other end of the floating pipe is provided with a water inlet and outlet port; the cage frames have bearing-frame-shaped reinforcing steel bar structures, a plurality of layers of polyethylene choice rare seafood cultivation cages are vertically arranged and placed in the cage frames on both sides of the floating pipe, and blocky foam floats are bound on both sides of the cage frames; at least three cage frames are bound on the floating pipe; the depth fixation device comprises a lifting rope and a sunken stone; and the buoyancy of the floating pipe in a completely hollow state is greater than the total weight of the cage frames and thedepth fixation device. The cultivation device can be sunk into the water bottom or different water layers for aquaculture production by a submersion control technology according to the characteristics of benthic growth environments of choice rare seafood, can be arranged in wider open sea areas, has the effects of resisting the attack of strong storm and escaping red tide disasters, can be quickly and safely floated and submerged, is easy to operate, and can be flexibly moved; and the device is a novel submersible fish shelter, and a novel cultivation and multiplication mode is provided for the construction of marine ranching.

Description

technical field [0001] The invention relates to the field of marine aquaculture facilities, in particular to a submersible and buoyant intensive sea treasure cultivation device with a single floating tube. Background technique [0002] In recent years, with the rapid development of my country's economy and the continuous improvement of people's living standards, people's demand for sea treasures is also increasing, thus promoting the development of sea treasures breeding industry. [0003] Sea treasures—sea cucumbers, abalones, sea urchins and other bottom-dwelling marine organisms are generally cultured in the following ways: raft culture, subtidal caisson culture on rocky reefs, enclosed pond culture in intertidal zones, subtidal culture with stone nets, and land-based factories methods such as chemical breeding, bottom broadcasting and streaming multiplication. [0004] Because raft farming needs to adjust the water layer with the change of seasons and sea conditions, so...

AI Technical Summary

Problems solved by technology

[0004] Because raft farming needs to adjust the water layer with the change of seasons and sea conditions, sometimes the ropes of the cages are very long, and the irregular water flow can easily cause the mutual entanglement of the breeding cages, which will bring losses to the breeding production; the other is the load of the farming raft frame It is very large. If it encounters bad weather, the waves are strong and the current is fast, the force of the raft frame will increase due to the force of the waves and currents, and there is a danger of being uprooted at any time.

In caisson farming, reefs are added to the caisson and sunk to the bottom of the water, which makes the work of inspection, feeding, and removal of harmful organisms more cumbersome. It is necessary to use a larger boat with a boom to lift the caisson to the ship for operation, which is more convenient for offshore operations. management inconvenience

The operating cost of industrial farming is high, the investment in facilities is large, the energy consumption of large-scale production is large, and the quality and growth speed of sea treasures are not higher than those in natural sea areas.

Pond aquaculture and subtidal zone aquaculture are also troubled by problems such as being easily polluted by the offshore seawater environment, large water temperature changes, high disease rates, and short aquaculture cycles.
