Embodiment

[0047] Ripening and induction of parental parents: In April 2009, the parental culture water temperature of northern bay scallop (Argopecten irradians irradians) and Peruvian scallop (Argopecten purpuratus ) was raised to 20°C and maintained at 20°C to promote ripening at constant temperature. The starting temperature of the ripening of the bay scallop broodstock is consistent with the local natural seawater temperature at that time, which is 7°C; the starting temperature of the Peruvian scallop broodstock ripening is consistent with the natural seawater temperature of the introduced place at the time of introduction, which is 11°C; the temperature rises each day 1°C, gradually raised to 18°C, stabilized for 3 days, and then raised to 20°C for constant temperature cultivation; the process of promoting ripening lasted for 18 days; the feed was fresh diatoms, supplemented with artificial feed egg yolk, and the egg yolk accounted for 10% of the total weight of the feed. 10%; dry t...

Abstract

The invention discloses a method for preparing male sterile bodies of argopecten irradians. Argopecten purpuratus which is homogeneous with the argopecten irradians, has the same chromosome number and similar gamete form and size as the argopecten irradians and is androgynous is selected to hybridize with the argopecten irradians so as to prepare male sterile bodies. The testes of the male sterile bodies are gradually substituted by ovaries together with the development of gonads; and when the gonads are mature, the whole gonads are orange red special in female, can only produce ova and cannot produce sperms. The method disclosed by the invention has the advantages of high proportion of sterile bodies, stable technical effect, relative simpleness, easiness for popularization.

Description

technical field [0001] The present invention relates to bay scallops, in particular to a preparation method for interspecies hybridization of northern bay scallops (Argopectenirradians irradians) and Peruvian scallops (Argopecten purpuratus ) to obtain male sterile bodies, and in particular provides a hermaphroditic bay scallop male sterile body preparation method. Background technique [0002] The preparation of male sterility has always been the key to productive complete hybrid seed production of bay scallop. Northern bay scallops (Argopecten irradians irradians) are native to the Atlantic coast of the United States, the left and right shells are almost equal, the shell surface has 16-21 radial ribs, the suitable temperature is 2-34°C, and the suitable salt is 25-34°C. Phytoplankton and organic debris for food. The breeding season in the original place is from September to October. The seedlings can reach more than 5cm in the autumn of that year, and the larger individ...
