Report of the Kumamoto Brood Stock Workshop. Held in Portland, Oregon on January24, 1992

摘要

The west coast oyster industry should take immediate steps to preserve thegenetic integrity and diversity of its Kumamoto oyster brood stocks. Employing currently available diagnostic methods, the initial steps for identifying pure Kumamoto brood stock would be: (1) strict selection of candidates with Kumamoto morphology and growth history; (2) nondestructive (thermal) induction of spawning; (3) testing of sperm for inability to fertilize Pacific oyster eggs; (4) sampling of larvae for mitochondrial DNA typing; (5) sampling of progeny at an early juvenile stage for enzyme typing; (6) conservation of brood stock whose progeny are diagnosed as pure Kumamoto and culling of those individuals whose progeny carry Pacific oyster genes.
