摘  要：
为了提高海区养成期间大珠母贝的生长性状,2010年6月—2011年6月,设立了2个实验组分别比较了养殖水深和笼具对大珠母贝成活率与生长的影响。实验I水深设为4组:HA组:3m;HB组:6m;HC组:9m;HD组:12m;实验II笼具设为3组:BN组:盒形笼;CN组:锥形笼和LN组:柱形笼;在第90、180、270、360天,比较2个实验I和II内各组的成活率与生长性状差异。结果表明:实验I,在第90、180、270天各组间的成活率差异不显著(P>0.05),在第360天各组间的成活率差异显著(P<0.05),在第90、180,270、360天HD组具有最大的成活率;在第90、180、270、360天,各组间的平均壳高与体重差异不显著(P>0.05)。实验II,在第90和180天各组间的成活率差异不显著(P>0.05),在第270、360天各组间的成活率差异显著(P<0.05),在第90、180、270、360天LN组具有最大的成活率;在第90、180、270天,各组间的平均壳高与体重差异不显著(P>0.05),在第360天各组间的平均壳高与体重差异显著(P<0.05),在第90、180、270、360天LN组具有最大的平均壳高与体重。说明了大珠母贝合适的养殖水深为6～9m,幼苗到成贝的合适养殖笼具为柱形笼。

摘  要：
Two experiments (Experiment I and II) were established to evaluate the effects of water depth and culture net on survival and growth of pearl oyster Pinctada maxima from June 2010 to June 2011,with an aim to improve growth traits of the stocks.Four groups were set in Experiment I:HA,3 m;HB,6 m;HC,9 m;and HD,12 m.Three groups were set in Experiment II:BN,box net;CN,cone net;and LN,cylinder net.At days 90,180,270,360,survival and growth of the groups in Experiment I and II were compared.In Experiment I,there were insignificant differences in survival rate among the four groups at days 90,180,270 (P>0.05).At days 360,the survival rate among the four groups differed significantly (P<0.05).The HD group had the largest survival rate at days 90,180,270 and 360.Insignificant differences in mean shell height and total weight among the four groups were observed (P>0.05).In Experiment II,survival rate among the BN,CN and LN groups were insignificant at days 90 and 180 (P>0.05).At days 270 and 360,however,the difference in survival rate among the three groups was significant (P<0.05).The LN group had the largest survival rate at days 90,180,270 and 360.At days 90,180 and 270,mean shell height and total weight differed insignificantly among the three groups (P>0.05).Differences in mean shell height and total weight were significant (P<0.05).The LN group displayed the largest mean shell height and total weight at days 90,180,270 and 360.The present results suggested that optimal water depth and culture net was 6-9 m and cylinder net suspended in the sea.
