| 摘 要： |  根据2014年8月—2015年2月于南海北部海域采集的金线鱼(Nemipterus virgatus) 106尾，测量其耳石样本的长、宽、周长、面积等形态指标，分析耳石形态特征，以探讨其耳石形态特征与个体体长、体质量的关系。结果表明，金线鱼耳石的形态指标在雌、雄个体间差异不显著(P>0.05)。耳石的宽、面积及长宽比在左右耳石之间存在显著性差异(P<0.05)，但耳石的长、最大半径、最小半径、周长、最小外接矩形面积和半径比在左右耳石之间差异不显著(P>0.05)。  经主成分分析发现，耳石的长、宽、最大半径、最小半径、周长、面积、最小外接矩形面积和半径比这8个形态指标为金线鱼耳石的主要形态指标。金线鱼耳石主要形态指标与体长、体质量的最佳拟合函数为多项式函数。  |

| Abstract: | We studied the otolith length, width, perimeter and other morphological parameters of 106 samples of Nemipterus virgatus collected from the continental shelf of northern South China Sea during August, 2014 to February, 2015. Results show no significant difference between female and male in otolith morphological characteristics (P>0.05). There was significant difference between left and right otolith in otolith width, area and ratio of length-width (P<0.05), but no significant difference in otolith length, maximum radius, minimum radius, perimeter, area of minimum circumscribed rectangle and ratio of radius (P>0. 05). According to principal component analysis, the otolith length, width, maximum radius, minimum radius, perimeter, area, area of minimum circumscribed rectangle and ratio of radius were the main morphological indicators of N. virgatus otolith. The relationship among main otolith morphological characteristics and body length and body mass was fitted optimally by polynomial function. |
