Embodiment Construction

[0031] 1. Breeding of broodlings

[0032] It takes about 35 days to ripen broodstock. The ratio of diploid oysters to tetraploid oyster parents is 10:1. One diploid oyster can produce about 12 million D larvae that can produce young oysters.

[0033] Diploid oysters: select Pacific oysters with a shell length of more than 10 cm and divide them into individual parts, remove surface attachments, wash them, put them in net cages or scallop cages, and gradually increase the temperature to promote ripening after stabilization, and increase the input The amount of bait. and should be served multiple times. The types of bait include Nitztella crescentus, Phaeodactylum tricornutum, Golden algae, and flat algae. Due to the large amount of feces discharged by oysters, the bottom should be sucked in time (and new water should be added). In order to maintain the water quality, the pond should be poured once a day.

Abstract

The present invention is technological process and apparatus of culturing triploid solitary oyster on the basis of tetraploid oyster parent. The technological process includes breeding parent oyster, obtaining egg and generating triploid, larva culturing, no-adhesion metamorphosis, downward flow culturing, upward flow culturing, outdoor temporary culturing, raft type pruning in intertidal zone and commercial oyster purifying. The present invention combines the triploid technology and solitary oyster culturing technology to breed new oyster variety for large scale production. The triploid solitary oyster has great size, high saccharide content, high quality, good taste, and thus high marketability.

Description

technical field [0001] The invention relates to a triploid single oyster, in particular to a method for cultivating and large-scale production of a new type of triploid single oyster. 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 glycogen content is reduced, and the quality is reduced, which affects the market sales of the product. At the same time, due to physical weakness and environmental deterioration after breeding, large-scale deaths and disease epidemics are often induced, which seriously affects the economic benefits of oyster farming and the sustainable development of the industry. Triploid technology is an advanced biotechnology in the world...
