摘要

摘要本研究旨在计算和评估从埃及赫尔格达渔港采集的两种山羊鱼的不对称性，即黄条纹山羊鱼Mulloidichys flavorineatus（Lacepède 1801）和红海山羊鱼Parupeneus forskali（Fourmanoir&Guézé1976）。对M.flavolineatus和P.forsskali的不对称性评估对于证明不对称性对这一重要渔场幼虫定居的影响至关重要。计算了囊状耳石（矢状）生物测量的不对称性，即长度、宽度和质量。结果表明，两种受检山羊鱼的耳石高度的不对称值低于耳石长度。耳石长度和宽度的不对称值与鱼的总长度之间没有关系。两种山羊鱼计算的耳石质量不对称性都高于许多硬骨鱼。

Investigation of otolith asymmetry in Mulloidichthys flavolineatus and Parupeneus forsskali (Perciformes: Mullidae) from Egypt’s Hurghada fishing harbour on the Red Sea

Abstract The current study aims to calculate and assess the asymmetry of the two goatfish species, Yellowstripe goatfish Mulloidichthys flavolineatus (Lacepède 1801) and Red Sea goatfish, Parupeneus forsskali (Fourmanoir & Guézé 1976) collected from Hurghada fishing harbour, Egypt. The asymmetry valuation for M. flavolineatus and P. forsskali is imperative to demonstrate the impact of asymmetry on the larvae settlement in this vital fishing ground. Asymmetry was calculated for the saccular otolith (Sagittae) biometry, namely length, width, and mass. The results showed that the otolith height had a lower asymmetry value than the otolith length for the two goatfish species inspected. No relationship between the asymmetry value of otolith length and width and total fish length was observed. Both goatfish species’ calculated otolith mass asymmetry was higher than that of many teleost fish species.
