Triploid oyster bottom sowing breeding device and breeding method thereof

Abstract

The invention belongs to the technical field of oyster breeding, and particularly relates to a triploid oyster bottom sowing breeding device and a breeding method thereof. The triploid oyster bottom sowing breeding device comprises a first floating mat, a plurality of first placing plates are arranged in the first floating mat, first partition plates and second partition plates are arranged in the first placing plates, the first partition plates and the second partition plates divide the first placing plates into a plurality of first placement cavities, and a plurality of first water through holes are formed in the bottoms of the multiple first placement cavities. By arranging the first floating mat, a plurality of first placing plates are arranged in the first floating mat, a plurality of placement cavities are arranged in the first placing plates, a plurality of first water through holes are formed in the bottoms of the first placement cavities, and a plurality of first flow guide plates are arranged at the bottom of the first placing plates, so that the tidal water resistance of the device and the survival rate of oysters are favorably improved, and cleaning is convenient.

Description

technical field [0001] The invention belongs to the technical field of oyster cultivation, and in particular relates to a triploid oyster bottom-sowing cultivation device and a cultivation method thereof. 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 dipl...

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
