摘  要：
以牙鲆为实验对象,研究了4种不同规格的T型标志牌(T-A、T-B、T-C和T-D)对全长5、7、9和11cm苗种的标记效果,确立了适宜标志的牙鲆苗种规格,筛选了适宜于不同规格牙鲆苗种标记用的T型标志牌。全长5cm的苗种不宜使用这4种规格的标志牌标记;T-A和T-B标志牌适宜于全长7~11cm的牙鲆苗种,标记后脱牌率为2%~8%,存活率为90%~100%;T-C标志牌适宜于标记全长11cm的苗种,成活率为94%,脱牌率为5%,对全长7~9cm苗种的标志效果不佳,成活率为85%~87%,脱牌率为9%~11%;T-D标志牌不适宜于全长11cm以下牙鲆苗种的标记,脱牌率为11%~26%,成活率为51%~89%。2011~2012年,利用T-B标志牌在北戴河开展了牙鲆大规模标志放流试验,取得了良好的标记效果。

Paralichthys olivaceus T-bar tags Tagging technique
摘  要：
Japanese flounder,Paralichthys olivaceus juveniles were tagged with four kinds of T-bar tags(T-A,T-B,T-C,and T-D).The tag-shedding rate,survival rate,swimming and feeding behavior,growth performance of juveniles post tagging were observed and recorded.Based on these data,we determined the suitable T-bar tag for Japanese flounder juveniles at different size.The results showed that all four kinds of T-bar tags were not suitable for Japanese flounder juveniles with total length less than 5cm due to the low survival rate and high tag-shedding rate.The T-A and T-B tags were suitable for Japanese flounder juveniles with total length of 7-11cm with survival rate of 90%-100%and tag-shedding rate of 2%-8%.For TC tag,the tag-shedding rate was 5% when it was used to tag juveniles with total length of 11 cm with survival rate of 94%.The T-C tag was not suitable for juveniles with total length of 7-9cm.For T-D tag,all groups showed low survival rates(51%-89%)and high tag-shedding rates(11%-26%)post tagging,therefore,the T-D tag was not suitable for juveniles less than 11cm in total length.Based on these results,we carried out pilot tagging studies on Japanese flounder juveniles using T-B tag from 2011to 2012.During this period,millions of juveniles were released into the sea,and 169,000juveniles were tagged using T-B tag,which would be helpful for evaluation of enhancement effects.
