Abstract

The invention discloses a device for ecologically culturing seashell and alga in shallow sea and a method thereof. The device comprises a seashell culture raft and an alga culture raft. The seashell culture raft comprises at least two paralleled floating ropes; buoys are arranged on the floating ropes and are connected with the floating ropes through floating ties; the two ends of each floating rope are fixed by underwater fixing mechanisms; the alga culture raft made by at least one culture curtain is arranged above each two adjacent floating ropes; the adjacent culture curtains are fixed by floating bamboo perpendicular to the floating ropes; and the two ends of the floating bamboo are connected with the floating ties. The device can be used to carry out the hanging culture of the seashell on the floating ropes and carry out the culture of the alga in the culture curtains floating above the floating ropes, thereby realizing the composite culture of the seashell and the alga. The device and the method have the advantages of reducing the culture cost, improving the culture efficiency and culture space utilization factor, and having good effects on the comprehensive use of shallow sea waters, the improvement of the water environment and the prevention and control of diseases.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a marine aquaculture facility and an ecological aquaculture technology, in particular to a device and method for shallow sea ecological aquaculture of shellfish and algae. Background technique [0002] At present, shellfish culture methods mainly include methods such as bottom sowing culture, stake culture, longline culture, and fixed frame culture; algae culture methods mainly include longline culture, fixed frame culture, and raft culture. The yield per mu of these traditional breeding methods is low, and most of them are single-species separate breeding, occupying a large sea area. Contents of the invention [0003] The object of the present invention is to provide a shellfish and algae shallow sea ecological cultivation device. [0004] The object of the present invention is also to provide a method for shallow sea ecological cultivation using the above-mentioned dev...
