摘要: 耳石是头足类重要的硬组织之一,被广泛应用在头足类渔业生物学、生态学研究中。根据2018年12月中国鱿钓船在日本海采集的261尾舍氏贝乌贼(Berryteuthis magister shevtsovi)样本,对其耳石外部形态生长特性进行了研究。主成分分析表明,耳石总长(TSL)、翼区长(WL)、吻侧区长(RLL)和最大宽度(MW)可以作为舍氏贝乌贼耳石外形变化的表征参数。协方差分析表明,舍氏贝乌贼耳石的表征参数与胴长及体质量的生长关系均不存在性别间显著性差异。赤池信息准则分析表明:TSL和WL与胴长的生长关系最适合用线性生长方程表示,RLL与胴长的生长关系最适合用幂函数生长方程表示,MW与胴长的生长关系则最适合用对数生长方程表示;TSL和MW与体质量的生长关系最适合用线性生长方程表示,WL与体质量的生长关系最适合用幂函数生长方程表示,而RLL与体质量的生长关系则最适合用对数生长方程表示。舍氏贝乌贼耳石绝对尺寸随着胴长增加而逐渐增大,但耳石各外部形态参数的相对尺寸基本不变。

Abstract: Statolith is one of the most important hard tissues in Cephalopods, which is widely used in the study of Cephalopod fishery biology and ecology. Based on 261 samples of Berryteuthis magister shevtsovi collected in theJapan Sea in December 2018 by the Chinese Jigging fleets, we examined the statolith shape and growth characteristics. The results of principal component analysis showed that the total statolith length (TSL), wing length (WL), rostrum lateral dome length (RLL) and maximum width (MW) could be used as the morphological characteristic parameters to study the morphological growth of statolith. The analysis of covariance showed no significant gender difference in the relationships between the morphological characteristic parameters and mantle length (ML) as well as body weight (BW). Akaike’s information criterion indicated that linear function could be best describing the relationships between ML and TSL or WL, power functions were best for the relationships between ML and RLL, and logarithm functions for ML and MW. The relationships between BW and TSL, BW and MW were best described by linear functions, but power function for BW and WL. The relationship between BW and RLL was best described by logarithm function. The absolute size of statolith gradually increased with increasing ML, but the morphological structure ratio of statolith remained basically unchanged.
