Simple efficient marine raft-type cultivation cage and using method thereof

Abstract

The invention discloses a simple efficient marine raft-type culture cage and a using method thereof, belongs to the field of seafood culture, and comprises a culture cage body system, a feed casting system and a cleaning system. The cleaning system and the feed casting system are independent matched devices and are respectively used for cleaning and casting a feed. The culture cage body system isinternally divided into a feed area and a farming area, the junction of the two areas is separated by a cylindrical plastic net with meshes A, and a compressing device is arranged in the feed area andused for providing a feed compressing function. After the feed is cast, the compressing device expands to enable the feed area to be in an expanded state, the feed is tightly compressed on the plastic net, and organisms obtain the feed through the meshes A; when the cleaning system cleans residual feed or rotten feed, the compressing device contracts to enable the feed area to be in a contractedstate for cleaning. According to the invention, the operation management process is greatly simplified, and the farming efficiency is improved; for cultured organisms, the feeding efficiency is high,and the morbidity and mortality of the organisms can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of sea treasure cultivation, and relates to a sea treasure cultivation equipment, in particular to a cage used for sea raft cultivation of abalone and sea urchin. Background technique [0002] Both abalone and sea urchin are rare sea treasures, rich in protein, fatty acid, vitamins and other nutritional elements necessary for the human body. They are delicious and loved by people. The market demand for abalone and sea urchin has greatly promoted the development of its industry. [0003] At present, sea raft farming is the main farming method of abalone and sea urchin in my country. Under this culture mode, the existing abalone and sea urchin raft culture techniques all use specially-made combined culture net cages (commonly known as abalone cages) or flexible multi-layer culture net cages (commonly known as scallop cages) suspended in various floating bodies. , Feeding kelp, asparagus, wakame and other large algae f...

AI Technical Summary

Problems solved by technology

2) Difficulty in feeding / cleaning residual bait: bait and organisms are mixed together, it is extremely difficult to clean rotten bait, and forced cleaning can easily cause damage to organisms

3) Low production efficiency: two workers in production can only manage about 150 cages a day

[0006] For aquaculture organisms: 1) Small space for activities: when a sufficient amount of bait is fed, the abalone or sea urchin is not separated from the bait, squeezed into a small space, and the density is too high, which greatly affects the growth of the organism

2) Poor feeding environment: For the rotten bait, if it is not cleaned up in time, the organism will be forced to eat the rotten bait, which is one of the main reasons for the disease and death of the organism

3) The water quality deteriorates quickly: the pushing of feces, rotten bait and biological corpses in the cage is very easy to breed bacteria and deteriorate the water quality, especially during the high temperature period in summer, the mortality rate is extremely high
