Floating and rope extending type aquaculture facility and method

Abstract

The invention relates to an aquaculture facility applicable to open sea areas where waves are huge and flow is rapid as well as a method. The facility comprises culture containers, floating bodies, a hanging rope, a main rope, a seedling rope, weight stones, a cable, an anchor, a signal rope and signal drifts, wherein, the floating body is tied to the upper end of the culture container, and the lower end of the culture container is tied to the main rope through the hanging rope, so that the culture container is positioned above the main rope; the distance that the main rope and the culture containers are away from the sea floor can be adjusted by adjusting the lengths of the seedling rope and the cable ; the signal shifts float on the water surface and are connected with two ends of the main ropes through the signal rope; and when the facility is operated, the main rope is pulled out of the water surface through the signal rope, the culture containers are cast with bait and harvested one by one along the main rope, or the culture depth is regulated. The facility and the method have the advantages that the culture containers can be protected from the influences of wind and waves on sea water, damages to cultured organisms and the facility by bad weather are avoided, cultured organisms can be farmed in clean outer lakes where water layer is the most proper and water flow is unobstructed as well as open sea areas around islands, the culture containers suspend, the weight of the facility is reduced, and the labor intensity is reduced. The facility is applicable to abalone culture and to culture of fixed type aquatic animals and plants (such as oyster and kelp) or aquatic animals and plants which have a certain attachment ability (such as sea cucumber).

Description

Technical field: [0001] The invention relates to a suspended longline aquaculture facility and method suitable for shallow ocean waves, high currents, and typhoon-prone sea areas. The present invention is applicable to abalone, and is also applicable to oyster, scallop, sea cucumber and various aquatic animals and plants with fixed type or certain adhesion ability. Background technique: [0002] my country's marine aquaculture mainly includes: factory aquaculture and marine aquaculture. The water environment of industrial aquaculture is not affected by external factors such as weather and sea conditions. The degree of intensification of aquaculture is high, and the operation and management of feeding, changing water, observation, and disease prevention are more convenient, and the output per unit area is high. However, the investment cost of facilities is high, the payback period of funds is relatively long, the breeding density is high, diseases are prone to occur, and the...

Problems solved by technology

[0003] In order to avoid the impact of surface wind waves and bad weather on the breeding container, expand the breeding area of ​​economical marine organisms, and improve the success rate of breeding production, the present invention provides a suspended longline aquaculture facility and method to solve the problem of large wind and waves The problem of serious losses caused by raft culture in the sea area, this facility can completely avoid the influence of the upper seawater wind and waves on the culture container and floating body, and avoid the damage caused by bad weather to the cultured organisms, especially suitable for open waves and large currents Sea life farming in urgent sea areas
