企鹅珍珠贝游离珠培育的初步观察

分别用锥形笼吊养法和塑料笼吊养法进行企鹅珍珠贝植核母贝的术前处理、在核位的左袋和右袋进行植核培育游离珍珠。经过13~15d的术前处理,锥形笼吊养法和塑料笼吊养法养殖的母贝成活率分别为93.67%和85.67%。经2个月休养,左袋插核的育珠贝死亡率和留核率分别为41.85~42.76%和10.34~12.96%;右袋插核的育珠贝死亡率及留核率分别为39.0%~40.0%和19.67%~20.00%。结果表明,合适的企鹅珍珠贝术前处理方法为锥形笼吊养法,合适的植核部位为右袋。

PRELIMINARY OBSERVATION ON ROUND PEARL PRODUCTION FROM PEARL OYSTER PTERIA PENGUIN(R(O)DING)

During round pearl production with Pteria penguin,the cone cages and plastic cages were used in the preoperative weakening process of adults Pteria penguin,and the left pearl-sac and right pearl-sac of a host pearl oyster was implanted a round nucleus and a piece of mantle tissue to produce round pearl.The survival rate of the adults was 93.67% and 85.67% after preoperative weakening process in cone cages and plastic cages for 13-15 days.And after 2 months rehabilitation,the mortality and retention rate of the producing shells that was implanted into a nucleus and a piece of mantle tissue in left pearl-sac was 41.85-42.76% and 10.34-12.96%,respectively;and those in right pearl-sac were 39.0-40.0% and 19.67%-20.00%,respectively.The result showed that the proper preoperative weakening process of adults Pteria penguin should be cultured in cone cages,and the nucleus should be implanted in right pearl-sac.
