Method and device for raising abalones by open-type net cages

Abstract

The invention relates to the technical field of aquaculture and technology for raising a precious marine product of abalones, in particular to a method and a device for raising abalones by open-type net cages. By the method and the device, a new mode for raising abalones in southern and northern provinces is realized, and a high-efficient environment-friendly mode for raising abalone-kelp integrated culture is formed. Compared with the conventional suspension cage culture, the small open-type net cage culture has smoother water flow and is more convenient to operate, particularly the phenomenon that the abalones are dehydrated due to lifting feed is avoided, so that the survival and the growth of abalones are benefitted. The raising capacity of one small net cage is close to 20 times that of one suspension cage; and simultaneously, because the small net cage culture is open, pollution to marine environment is avoided, and the device and the method accord with the ecological idea of sea ranching.

Description

[0001] Technical field [0002] The invention relates to the technical field of aquaculture, and relates to the culture technology of abalone, a sea treasure, and in particular to an open cage abalone culture method and device. Background technique [0003] Abalone is one of the rare sea treasures. The meat is tender, fresh but not greasy; it is rich in nutrition, clear and rich in flavor, and it is delicious in cooking and soup. Abalone is rich in protein, and there are more nutrients such as calcium, iron, iodine and vitamin A. Abalone is rich in globulin. The meat of abalone also contains an ingredient called "baosu", which can Destroy the metabolites necessary for cancer cells. Abalone nourishes but not dry, nourishes the liver and improves eyesight. It not only has high nutritional value, but also has medicinal value. Known as the "crown of seafood", abalone has been one of the "eight treasures" of seafood since ancient times. one. [0004] There are many ways to breed...

AI Technical Summary

Problems solved by technology

However, the bottom sowing breeding has high requirements on the bottom quality of the sea area, and the breeding area is limited; the floating raft culture generally adopts flexible combined abalone breeding net cages, and uses plastic pots inside the net bags as abalone breeding equipment, or adopts multi-layer closed cages. In the cultivation process, it is necessary to manually pull up the breeding net cage for bait feeding, and the bait needs to be chopped. The labor intensity of the workers is very high, and the work efficiency is low.
