Abstract

The invention discloses a seedling collecting method for treating pinctada maxima attached seedlings through high-specific-gravity seawater soaking, and belongs to the technical field of aquaculture. The method comprises the steps of water storage container preparation, high-specific-gravity seawater preparation, high-specific-gravity soaking seawater preparation, attached seedling soaking treatment, seedling collection treatment and seedling culture. According to the method provided by the invention, the high-specific-gravity seawater is adopted to soak and treat the seedlings of the pinctada maxima attached to a seedling collector, the seedlings fall off automatically, damage to the seedlings during manual seedling collection is reduced, the breeding survival rate of the seedlings of the pinctada maxima is increased, and the method is easily popularized and applied in pinctada maxima seedling production units and has good economic benefits and ecological benefits.

Description

technical field [0001] The invention relates to a method for collecting attached seedlings of Pinctada maxima, which belongs to the technical field of aquaculture and is suitable for collecting seedlings attached to seedling picking devices of Pinctada maxima in artificial seedling cultivation. Background technique [0002] Pinctadamaxima Jameson, also known as white butterfly oyster, includes Silver lip pearl oyster (Silver lip pearl oyster) whose nacre edge is silvery white on the inner surface of the shell and Gold lippearl oyster (Gold lippearl oyster) whose nacre edge is golden yellow , is a national second-class protected wild animal. Large pearl oysters inhabit tropical and subtropical waters, such as the coasts of northwest Australia, Indonesia, Malaysia and Myanmar, as well as the coasts of Leizhou Peninsula in southwestern Guangdong Province, the waters around Weizhou Island in Guangxi, around Hainan Province and the Paracel Islands. Pearl oyster is the largest ma...
