This study evaluated potential differences in morphology of unextruded larvae from Sebastes mentella and Sebastes norvegicus in Icelandic waters. Fifty-four larvae of each species were measured, and 18 measurements were recorded for each specimen (morphometric, meristic and pigmentation patterns). Pre-extrusion larvae of S. norvegicus were longer than those of S. mentella. Additionally, there were significant differences in morphometric, meristic and pigmentation characters between pre-extrusion larvae of these species. Pigmentation of S. mentella differed from that of S. norvegicus in several aspects. Dorsal and ventral body pigmentation tended to begin more posteriorly in S. mentella, therefore, the overall length of these pigmented areas tended to be longer in S. norvegicus.
本研究评估了冰岛水域未挤出的拟庸鲉属和北梭鱼属幼鱼形态的潜在差异。对每个物种的 54 个幼鱼进行了测量,每个标本记录了 18 个测量值(形态、可数和色素模式)。挪威拟庸鲉的未挤出幼鱼比拟庸鲉属的幼鱼更长。此外,这些物种的未挤出幼鱼在形态、可数和色素特征上存在显著差异。拟庸鲉的色素与挪威拟庸鲉在几个方面存在差异。背部和腹部的身体色素往往在拟庸鲉中更靠后开始,因此,这些着色区域的总长度在挪威拟庸鲉中往往更长。
