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...

Examples

Embodiment 1

[0027] Example 1: Suspension rope-type abalone cultivation in open sea area

[0028] In this example, on May 30, 2011, in the sea area south of Nanri Xiaori Island, 35 nautical miles away from the shore, the highest water depth at high tide was 12m, and the lowest water depth at ebb tide was 8m. The length of the main rope is 100m, the main rope is 4m away from the seabed, and a culture container is suspended every 3m, and the culture cage is more than 3m below the low tide water surface. The breeding container is a PVC pipe with a diameter of 25 cm x a length of 60 cm, and 60 abalones of 4.5 cm are placed in each pipe. After breeding for 4 months, the survival rate of abalone is 80.2%, and the average shell length is 5.6cm. The shell color of the abalone is full, without floating mud, less attached organisms, and in good condition.

[0029] The same batch of abalones were stocked with the same size and density. The raft-type culture was carried out at the mouth of the Nanri...
