摘　　要：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。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, swim ming and feeding behavior, growth performance of juveniles post tagging were observed and re corded. Based on these data, we determined the suitable T-bar tag for Japanese flounder juven- iles 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 5 cm 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 to- tal length of 7-11 cm with survival rate of 90%-100% and tag-shedding rate of 2%-8%. For T- C tag, the tag-shedding rate was 5% when it was used to tag juveniles with total length of 11cm with survival rate of 94%. The T-C tag was not suitable for juveniles with total length of 7- 9 cm. 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 11 cm in total length. Based on these results, we carried out pilot tagging studies on Japanese flounder juveniles using T-B tag from 2011 to 2012. During this period, millions of juveniles were released into the sea, and 169,000 juveniles were tagged using T-B tag, which would be helpful for evaluation of enhancement effects.
