摘要/Abstract

摘要： 角质颚是研究头足类渔业生态学的重要材料.基于2018年9—11月中国鱿钓船在西北太平洋生产调查期间采集的268尾北方拟黵乌贼样本,对其角质颚外部形态生长特性进行了研究.主成分分析表明: 北方拟黵乌贼角质颚的上头盖长(UHL)、上脊突长(UCL)、上喙长(URL)、下头盖长(LHL)、下脊突长(LCL)和下喙长(LRL)可作为研究其角质颚外形变化的特征因子.协方差分析表明: 各特征因子与胴长和体重的生长关系在性别间均不存显著性差异.赤池信息准则分析显示: UHL、LHL与胴长生长的关系最适于用幂函数表示,UCL、URL、LCL与胴长生长的关系最适于用对数函数表示,而LRL与胴长生长的关系则最适于用线性函数表示;各特征参数与体重生长的关系,除LHL最适于用幂函数表示外,其余均最适于用对数函数表示.外形特征因子生长模型的确定,为北方拟黵乌贼的资源评估等研究打下科学基础.

Abstract: Beak is one of the most hard tissues in cephalopods, which is important in the study of fishery ecology. We analyzed the morphological growth characteristics of 268 beaks of Gonatopsis borealis collected in the Northwest Pacific Ocean from September to November of 2018 by Chinese jigging fishing fleets. Results from the principal component analysis showed that the upper hood length (UHL), upper crest length (UCL), upper rostrum length (URL), lower hood length (LHL), lower crest length (LCL) and lower rostrum length (LRL) could be used as the morphological characteristic parameters to study the morphological growth of beak. Results from the analysis of covariance (ANCOVA) showed that there was no significant difference both in the relationships between the morphological characteristic parameters versus mantle length (ML) or body weight (BW) for males and females. The relationships between ML and UHL, LHL were best described by power functions but by logarithm function for UCL, URL, LCL, and linear function for LRL respectively. The relationships between BW and UHL, UCL, URL, LCL, LRL were best described by logarithm functions but power function for LHL based on the result of the Akaike’s information criterion. The results of growth models for the morphological parameters in this study provided scientific basis for the stock assessment in further research.
