对天津汉沽区海域渔获物银鲳的形态学性状进行测量分析。结果表明：全长/体长为1．45±0．04，体高/体长为0．54±0．03，头长/体长为0．24±0．01，尾柄高/体长为0．09±0．006，眼间距/体长为0．10±0．006，眼径/体长为0．08±0．005，肠长比为2．81±0．33。背鳍43～48、尾鳍22～36，胸鳍20～33，臀鳍42～49、鳃耙19～24，幽门盲囊169～272，椎骨31～37。当样本个体大小处于同一水平时，以身体主要部分的比例特点为依据难以进行性别区分，可数性状亦不能作为性别区分的可靠依据。另外，不同地理群体样本的可数性状差异与生长阶段和环境因素均有关系。%The silver pomfret samples were collected from the fishing vessel in Hangu sea area ,and the morphological characteristics of them were measured .The total length ,body height ,head length , caudal peduncle depth ,eye distance ,eye diameter and intestines length were 1 .45 ± 0 .04 ,0 .54 ± 0 .03 ,0 .24 ± 0 .01 ,0 .09 ± 0 .006 ,0 .10 ± 0 .006 ,0 .08 ± 0 .005 and 2 .81 ± 0 .33 times of body length re-spectively .And the dorsal fin ,caudal fin ,pectoral fin ,anal fin ,gill raker ,pyloric caecas and Verte-bra have 43~48 ,22~36 ,20~33 ,42~49 ,19~24 ,169~272 and 31~37 respectively .While the length of spacemen was in the level of narrow range ,the sex of silver pomfret can’t be identified by the main morphological characters ,and the value of countable characters were influenced by different grow th stage and environment condition .
