Abstract

The invention discloses a bottom-sowing cultivation method of Hepu pearl oyster, comprising the following steps: S1: designing a Hepu pearl oyster bottom-sowing cultivation device; S2: labeling Hepu pearl oyster seedlings in a sea area by hanging them in net bags Coarse; S3: Put the Hepu Pinctada seedlings evenly on the bottom seeding board after the roughness, and temporarily raise them in the cement pool with seawater until the Hepu Pinctada grows silk; S4: Select the shallow beach, Fix the fixed column in the shallow beach, set the connecting rope on the fixed column, take out the bottom sowing board from the cement pool, place it in the shallow beach, arrange it in sequence and connect it to the connecting rope, and then adjust the Hepu according to daily management. Pearl oyster can be cultivated. This method makes the individual distribution of Hepu Pinctada more uniform, and reduces the pressure of space and bait competition between individuals, which is more conducive to improving the growth rate of Hepu Pinctada, the survival rate of culture, and reducing the growth difference between individuals, and the culture equipment and culture The method is simple to operate and can reduce breeding costs and labor.

Description

technical field

[0001] The invention belongs to the technical field of cultivation, and in particular relates to a bottom-sowing cultivation method of Hepu pearl oyster. Background technique

[0002] Hepu mother-of-pearl is widely distributed in tropical and subtropical regions and is an important mother-of-pearl for cultivating seawater pearls. Since Hepu pearl oyster successfully broke through artificial seed breeding in 1965, its cultured area and output have continued to increase, and pearl culture of Hepu pearl oyster once became one of the pillar industries in some coastal areas such as Guangdong, Guangxi and Hainan.

[0003] However, due to backward breeding technology, outdated farming models, aging breeding sites and deteriorating breeding environment, the cultured Hepu Pearl oyster grows slowly. And due to the lack of systematic artificial breeding in the long-term cultivation process, the high-quality germplasm resources of Hepu pearl oyster are lacking, resultin...
