Pacific oyster no-damage sampling method

Abstract

The invention discloses a pacific oyster no-damage sampling method, comprising the following steps of: a, firstly soaking pacific oyster for 10-15 hours with MgCl2 sea water solution with the concentration of 3-5%; b, then disinfecting a scalper or dissecting scissors with 70% alcohol, and scissoring pallium or gill of the pacific oyster; and c, washing the pacific oyster subjected to sampling operation in the steps a and b for 3-4 times with sea water, and putting the pacific oyster back into a breeding box for breeding. According to the method, a pacific oyster no-damage sampling method is established in a pacific oyster selective breeding process, an ideal parent can be provided for pacific oyster quality character family breeding, the method disclosed by the invention also can be applied to polyploidy breeding, and no-damage ploidy detection can be carried out on a polyploidy. High-quality varieties with good meat quality, fast growth speed and strong stress resistance are bred through selective breeding, or a triploid is obtained by adopting a polyploidy breeding technology, thus product quality of pacific oyster in China is improved.

Description

technical field [0001] The invention belongs to the technical field of shellfish breeding, and in particular relates to a non-damaging sampling method for long oysters. Background technique [0002] Long oyster (Crassostrea gigas) is the most widely cultured and most productive economic shellfish in the world, and it is also the most important marine cultured shellfish in my country. Long oysters are widely cultured in my country's coastal areas due to their advantages such as strong adaptability, large individuals, short breeding cycle, and plump meat. [0003] In recent years, although the cultivation scale of long oysters has been gradually expanded and the output has been greatly increased, the quality of long oysters has been declining, and the germplasm has also degraded. The specific manifestations are low meat yield, irregular shape, and poor meat quality. , Seriously affecting the development of long oyster aquaculture. At present, most of the seedlings required f...
