Bottom sowing culturing method for pinctada fucata

Abstract

The invention discloses a bottom sowing culturing method for pinctada fucata. The bottom sowing culturing method for the pinctada fucata comprises the following steps: S1, designing a bottom sowing culturing device of the pinctada fucata; S2, coarsening juvenile pinctada fucata in a sea area in a net bag hanging mode; S3, uniformly placing the coarsened juvenile pinctada fucata on bottom sowing plates, and temporarily culturing the juvenile pinctada fucata in a cement pool provided with seawater until the juvenile pinctada martensii grows byssus; S4, selecting a shallow sea beach, fixing fixedcolumns in the shallow sea beach, arranging connecting ropes on the fixed column, taking out the bottom sowing plates from the cement pool, placing the bottom sowing plates in the shallow sea beach,sequentially arranging and connecting the bottom sowing plate to the connecting ropes, and culturing the pinctada fucata according to daily management. According to the method, the individual distribution of the pinctada fucata is more uniform, the inter-individual space and the bait competition pressure are reduced, so that the growth rate and the culturing survival rate of the pinctada fucata are improved, the inter-individual growth difference is reduced, the culturing device and method are simple to operate, and the culturing cost and the labor amount can be reduced.

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 [0003] However, due to backward breeding technology, outdated farming models, aging breeding sites and deteriorating breeding environment, the cultured Hepu Pearl oyster grows slowly.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...

Problems solved by technology

[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 attention to systematic artificial breeding during the long-term cultivation process, the high-quality germplasm resources of Hepu pearl oyster are lacking, resulting in a sharp decline in pearl production, which has brought huge losses to the pearl oyster cultivation industry, and the enthusiasm for pearl cultivation has gradually declined.

[0004] In the traditional cage culture mode, the pressure of competition among individuals of Hepu pearl oysters is high, the water flow is not smooth, the bait is insufficient, and the growth rate is slow. Moreover, Hepu pinnacle oysters cannot be completely exposed to sea water. Shellfish are affected, and the survival rate of breeding is low
