Fish morphometric relationships are key tools for fisheries science and studies of food web dynamics and predator foraging behaviour, but parameterisations are limited for Southern Ocean myctophids (Family Myctophidae). New standard length (LS) to total mass (MT) relationships are therefore described for the 12 biomass‐dominant myctophid fish species living in the Scotia Sea, Southern Ocean, using the most comprehensive data collected in the region to date. New linear regressions for otolith size (length; OL and width; OW) and LS are also described. Significant (p < .01) LSMT relationships were established for all species using simple non‐linear regression. Significant (p < .01) relationships between LS and both OL and OW were also determined for all species, with OW being the best predictor of LS in all but one species. Our study provides a comprehensive tool for reconstructing the myctophid component of marine predator diets that will improve future food web, predator behaviour and ecosystem studies in the Scotia Sea.

十二种南部大洋蛾科的体长,体重和耳石大小与标准体长的关系:捕食者饮食研究的工具

鱼的形态计量关系是渔业科学以及研究食物网动力学和捕食者觅食行为的关键工具,但是参数设置对于南大洋的Myctophidad(Family Myctophidae)是有限的。因此,利用迄今为止该地区收集的最全面的数据,描述了生活在南大洋斯科舍海地区的12种以生物质为主的Myctophid鱼类的新标准长度(L S)与总质量(M T)的关系。为耳石大小新的线性回归(长度; ø大号和宽度; ö W¯¯)和大号小号也有所说明。显着(p  <.01)L S使用简单的非线性回归为所有物种建立了M T关系。还确定了所有物种的L SO LO W 之间的显着(p <.01)关系,除了一个物种外,O WL S的最佳预测指标。我们的研究为重构海洋捕食者饮食中的杀线虫成分提供了一个全面的工具,这将改善今后在斯科舍海的食物网,捕食者行为和生态系统研究。
