Triploid oyster breeding device for shallow beach

Abstract

The invention belongs to the technical field of oyster breeding, and particularly relates to a triploid oyster breeding device for a shallow beach. The triploid oyster breeding device comprises a first floating mat, the first floating mat is provided with first partition plates and first breeding plates, the first partition plates and the first breeding plates are distributed on the first floating mat in a staggered mode, and the upper surfaces of the first breeding plates are provided with a plurality of breeding cavities. According to the triploid oyster breeding device for the shallow beach, the first floating mat is arranged, the first floating mat is provided with the first partition plates and the first breeding plates, the first partition plates and the first breeding plates are distributed on the first floating mat in the staggered mode, the multiple breeding cavities are formed in the upper surface of a first breeding plate, a plurality of water outlet holes are formed in the bottoms of the multiple breeding cavities, a plurality of hollow cavities are formed in the first breeding plate, the positions of the multiple hollow cavities correspond to the positions of the multiple breeding cavities, and the multiple hollow cavities and the multiple breeding cavities are communicated. Four flow guide plates are arranged at the bottom of the first breeding plate, so that the tide resistance of the triploid oyster breeding device for the shallow beach is improved.

Description

technical field [0001] The invention belongs to the field of aquaculture equipment, in particular to a triploid oyster cultivation device used in shallow beaches. 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 d...

[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
