Cultivation method of three-way hybrid scallop commodity offspring seeds

Abstract

The invention relates to the technical field of marine economic shellfish cross breeding, in particular to a breeding method based on argopecten purpuratus, argopecten irradians and Argopecten irradians concentricus three-way hybrid scallop commodity fries. The argopecten irradians and the Argopecten irradians concentricus are subjected to intersubspecific hybridization, then the obtained first-generation scallops of the intersubspecific hybridization and the argopecten purpuratus are used as seed scallops and are respectively subjected to high selfing purification, and the obtained purified sea and ink sea (or ink sea) hybrid scallops and the argopecten purpuratus are subjected to interspecific hybridization; therefore, large-scale preparation of the sea-black-black-purple (or black-sea-black-purple) three-way hybrid scallop commodity offspring seeds is realized. According to the method for preparing the three-way hybrid scallop commodity offspring seeds of the Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus,

Description

Technical field: [0001] The invention relates to the technical field of marine economic shellfish hybrid breeding, in particular to a method for cultivating commercial scallop seedlings based on the three-way hybridization of purple scallops, bay scallops and Gulf of Mexico scallops. Background technique: [0002] The northern subspecies of the bay scallop (Argopecten irradians irradians, referred to as the bay scallop) and the southern subspecies of the bay scallop (Argopecten irradians concentricus, also known as the Gulf of Mexico scallop) are native to the coast of the Americas, both of which are fast-growing shellfish. It was introduced into China in the 1990s and 1990s, and rapidly developed into the main cultured species of scallop in the northern and southern coastal areas of my country, triggering a development climax of my country's aquaculture industry (Zhang Fusui, 2014; Han Jiajun et al., 1998). In 2018, the aquaculture area of ​​Gulf scallops and Gulf scallops i...
