Deep-sea culture device for triploid oysters

Abstract

The invention belongs to the technical field of oyster breeding, and particularly relates to a deep-sea culture device for triploid oysters. The deep-sea breeding device comprises a first breeding mechanism and a first cleaning mechanism, openings are formed in the two ends of the first breeding mechanism, a first breeding plate is arranged in the first breeding mechanism, and the two ends of the first breeding plate are connected with the inner side wall of the first breeding mechanism. The first breeding mechanism is arranged, the first breeding plate is arranged in the first breeding mechanism, a plurality of breeding cavities are formed in the first breeding plate, a first groove is formed in the bottom of the first breeding plate, a first rotating plate is arranged in the first groove, and the capability of resisting tidal water of the device is improved; and the first cleaning mechanism is arranged, a plurality of first cleaning wheels are arranged at the bottom of the first cleaning mechanism, a first pipeline is arranged on the first cleaning wheels, and a plurality of first water outlets are formed in the outer surface of the first pipeline, so that the oyster cleaning process is facilitated, and the functionality of the device is improved.

Description

technical field [0001] The invention belongs to the field of aquaculture equipment, in particular to a device for deep-sea culture of oysters with three shells. Background technique [0002] The existing oysters are generally wild diploid oysters. Take Pacific oysters with a large amount of cultivation in recent years as an example. In the spring and summer of the second year, it has reached sexual maturity, and the sperm eggs are discharged in the sea area, so that the soft body of the oyster is thinned into "water oysters", the sugar content is reduced, and the quality is reduced, which affects the market sales of the product; Physical weakness and environmental deterioration often induce large-scale deaths and disease epidemics, seriously affecting the economic benefits of oyster farming and the sustainable development of the industry; triploid technology is an advanced biotechnology in the world; The chromosomes of normal diploid organisms are doubled to achieve the dou...

Problems solved by technology

[0002] The existing oysters are generally wild diploid oysters. Take Pacific oysters with a large amount of cultivation in recent years as an example. It has reached sexual maturity in the spring and summer of the second year, and the sperm eggs are discharged in the sea area, so that the soft body of the oyster is thinned into "water oysters", the sugar content is reduced, and the quality is reduced, which affects the market sales of the product; Physical weakness and environmental deterioration often induce large-scale deaths and disease epidemics, seriously affecting the economic benefits of oyster farming and the sustainable development of the industry; triploid technology is an advanced biotechnology in the world; The chromosomes of normal diploid organisms are doubled to achieve the doubling effect; the triploid species obtained after doubling treatment have sterility and many excellent traits, because their gonads are not developed or developed very small, and the obtained energy and Most of the substances are used for individual growth, so its growth speed is fast, its resistance is strong, and the edible part is plump and beautiful. What is especially important is that there is no sperm and eggs after sexual maturity. The quality is stable and can be harvested all year round; existing triploid oysters Net cages are commonly used for breeding, which has the problems of poor tide resistance, high oxygen content, a large amount of labor and difficult cleaning
