Embodiment 1

[0029] Taking the applicant's 2015 scallop seabed hanging ear cultivation experiment as an example, the technical solution of the present invention is described in detail.

[0030] The first-year-old scallop scallop that was bred locally in Zhangzidao in 2015 was selected as the experimental material. The average size of the first-year-old scallop is 6.72cm in shell height and 36.07g in weight. The experiment was carried out at the beginning of May 2015. 5,000 first-year-old shellfish were taken from the sea, and the ears were punched. After the holes were punched, they were put into the breeding cages. The density of each cage was 8 shells per layer for temporary breeding on floating rafts in the sea area. The temporary breeding time was one week. After one week, the dead first-ling shellfish were picked out, and the statistical survival rate was 92%; if figure 1 and figure 2 As shown, the surviving first-year-old shellfish, that is, the ear-piercing scallop 6, is fixed on...

Abstract

The invention belongs to the technical field of shellfish cultivation, and particularly relates to a sea-bottom ear-hanging cultivation method and device for patinopecten yessoensis. The method and device break through thinking limits of traditional buoyant raft and bottom sowing cultivation of patinopecten yessoensis, and an ear-hanging cultivation mode is converted into sea-bottom frame-type cultivation from sea-surface buoyant raft cultivation. According to the cultivation method and device, changes of water layers are adopted, and phenomena of more attachments and high summer death rate in surface cultivation are effectively reduced; a metal framework is adopted to serve as a cultivation support, the device is a flexible assembly and convenient to disassemble, components can be replaced after being damaged, material storage areas are saved and the cultivation cost is reduced; cultivation vessels are adopted to conduct fixed-point placement of the sea-bottom cultivation frame, recovery vessels conduct fixed-point recovery, the accurate placement is achieved, catching is accurate, the method and device avoid the problems that the utilization rate of sea area is low due to bottom sowing cultivation and submarine environment is severely damaged because of dragnet during bottom sowing all the year round, and the stability of cultivation is improved. According to the method and device, the new ear-hanging cultivation mode of patinopecten yessoensis is developed, industrialization, intensification and stereo cultivation are achieved, and the cultivation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of shellfish cultivation, and in particular relates to the research, development and application of a method and device for cultivating scallops with sea scallops. Background technique [0002] Ezo Scallops ( Patinopecten yessoensis ) belongs to cold-water shellfish, originating in the waters of Hokkaido, Japan, and is one of the important cultured economic shellfish in the world. Since it was introduced to the coasts of Liaoning and Shandong in China in the early 1980s, after nearly 30 years of cultivation, the artificial breeding and cultivation techniques of scallops have matured and become one of the main cultured shellfish in the northern coast of my country. In Changhai County, Dalian, Liaoning, in 1985, the aquaculture area of ​​scallops was 180 mu, and the output was less than 200 tons. After nearly 30 years of development, the aquaculture area reached more than 6 million mu by 2014, and the output ...
