Shipborne mariculture system

Abstract

The invention relates to a shipborne mariculture system, which comprises a ship hull, wherein a water chamber is arranged in the ship bull; a first horizontal pipeline is arranged on the broad side of the water chamber close to a bilge part in position; a water pump and a gate valve used for charging water are arranged in the first horizontal pipeline; a second horizontal pipeline is arranged on the broad side of the water chamber close to a water line in position; a gate valve used for discharging water is arranged in the middle of the second horizontal pipeline; a liftable steel mesh platform and a liftable hierarchical grid are arranged in the water chamber; and a water purifying system and an aerating oxygenation system are arranged in the water chamber. The shipborne mariculture system avoids water treatment of which the cost is higher and higher, and the offshore distance is long enough, so that seawater for mariculture can not be affected by external severe environment and pollution, and the safety and the quality of aquatic products are guaranteed. Owing to the moving capability of the shipborne mariculture system, the system can not only perform mariculture in sea areas with suitable water temperature and good water quality, but also avoid typhoon when meeting emergencies, and reduces the risk of mariculture.

Description

technical field [0001] The invention relates to the technical field of marine industrialized mariculture, in particular to a ship-borne mariculture system. Background technique [0002] At present, my country's marine aquaculture mainly includes pond aquaculture, direct row aquaculture, closed circulation aquaculture and cage aquaculture. Traditional aquaculture ponds have simple structures, poor facilities, and no treatment for inflow and outflow, which pollutes the environment and is easily affected by external water quality. It is an unsustainable aquaculture method at the expense of environmental quality. The direct-discharge flowing water aquaculture method consumes a lot of high-quality water resources, especially groundwater resources, causing many problems such as groundwater level drop and land subsidence. This one-time use of deep well seawater production method does not meet the requirements of efficient use of resources and energy. social requirements. After ye...

Problems solved by technology

Traditional aquaculture ponds have simple structures, poor facilities, and no treatment for inflow and outflow, which pollutes the environment and is easily affected by external water quality. It is an unsustainable aquaculture method at the expense of environmental quality.

The direct-discharge flowing water aquaculture method consumes a lot of high-quality water resources, especially groundwater resources, causing many problems such as groundwater level drop and land subsidence. This one-time use of deep well seawater production method does not meet the requirements of efficient use of resources and energy. social requirements

After years of development in closed recirculating aquaculture, the technology in the field of freshwater aquaculture has become mature. However, due to the toxicity of seawater salinity and the osmotic pressure of nitrifying bacteria, the progress of biological filtration technology in marine aquaculture systems has been slow, resulting in the failure of closed recirculating water systems. The operation is unstable, and the breeding effect is difficult to control

Research on the cage structure, anchoring system, feed storage, maintenance and management of cage culture has not yet been carried out, especially the research on anti-wind wave and anti-flow performance is not deep enough, and the economic losses caused by typhoons are very heavy

[0003] Due to the fact that the traditional marine aquaculture method cannot solve serious disease problems, drugs and antibiotics are used extensively in the aquaculture process, and the aquatic products produced are often suffered heavy losses due to problems such as substandard sanitation in export trade due to the lack of strict implementation of relevant hygiene testing standards.
