Abstract

Fluctuating Asymmetry (FA) in fish otoliths is an indicator of arbitrarily tiny variations between bilateral otolith characters, and it serves as an effective indicator of growth and developmental differences due to environmental conditions. Due to their unique resident traits, the Coilia brachygnathus can provide a potential insight to the environmental pressure reflected by its otolith FA. In this study, 228 C. brachygnathus from Changhu Lake were examined, assessing the Asymmetric Square Coefficient of Variation (CV2a) across four characters: the length, width, perimeter, and area of the left and right lateral sagittal otoliths. Results showed that otolith length exhibited the lowest CV2a, while otolith perimeter displayed the highest. Although no clear pattern emerged in the change of CV2a with increasing body length for each otolith character, the CV2a of otolith width within the 160–180 mm body length group was significantly higher than that in the 120–140 and 220–240 mm groups. Generally, otolith CV2a within the middle and upper lake sections surpassed that in the open water sections of the lower reaches. Our findings indicated that ontogenetically, variations in C. brachygnathus otolith FA are linked to its feeding and habitat preferences, while the spatial responsiveness of otolith FA to environmental pressure warrants further exploration. Future studies will encompass the collection of otolith FA data from additional Coilia species, with particular emphasis on distinguishing migratory and sedentary Coilia, ultimately enhancing the reliability and precision of environmental pressure assessments in inland waters.

长湖鲚(Coilia brachygnathus)耳石的波动不对称性:中国内陆水域的首次研究。
鱼类耳石中的波动不对称(FA)是双侧耳石特征之间任意微小变化的指标,也是环境条件导致生长和发育差异的有效指标。由于腕鳃鲚独特的栖息特征,其耳石的FA可能会反映出环境压力。本研究考察了228尾来自长湖的胭脂鱼,评估了左右侧矢状耳石长度、宽度、周长和面积四个特征的非对称平方变异系数(CV2a)。结果显示,耳石长度的 CV2a 最低,而耳石周长的 CV2a 最高。虽然各耳石特征的 CV2a 随体长的增加没有明显的变化规律,但 160-180 mm 体长组耳石宽度的 CV2a 明显高于 120-140 mm 和 220-240 mm 组。总体而言,中上游湖段的耳石 CV2a 高于下游开阔水域的耳石 CV2a。我们的研究结果表明,在个体发育过程中,胭脂鱼耳石FA的变化与其摄食和栖息地偏好有关,而耳石FA对环境压力的空间响应性值得进一步探讨。未来的研究将包括收集更多鲚鱼种的耳石FA数据,尤其侧重于区分洄游鲚和定居鲚,最终提高内陆水域环境压力评估的可靠性和精确性。

期刊介绍: Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
