Fish length and otolith size of in Nemipterus randalli Russel, 1986 (Actinopterygii: Perciformes: Nemipteridae) collected from Gökova Bay, Turkey

Otoliths have been proved an appropriate tool to identify fish species, and they have been in use in studies of prey-predator relationships, population dynamics and ichthyo-archaeology. In addition, the fish otoliths are frequently used to decide age and size of the teleost fishes. The relationships between otolith measurements (length, width, and weight) and fish length and weight were calculated for Randall's threadfin bream, Nemipterus randalli collected from Gökova Bay, Turkey. Otolith length, width and weight were shown to be good indicators of the length of fish, but the best indicator was the otolith length. Sizes of the left and right otoliths were found not be significantly different.耳石（otoliths）已被证实为识别鱼类物种的适宜工具，目前已应用于捕食者-猎物关系、种群动态及鱼类考古学的相关研究中。此外，鱼类耳石常被用于确定真骨鱼类（teleost fishes）的年龄与个体大小。本研究针对从土耳其戈科瓦湾（Gökova Bay）采集的兰氏金线鱼（Randall's threadfin bream，Nemipterus randalli），计算了耳石测量指标（长度、宽度与重量）与鱼类体长、体质量之间的相关关系。结果显示，耳石的长度、宽度及重量均可作为鱼类体长的良好指示指标，其中耳石长度为最优指示指标。研究同时发现，左右耳石的尺寸不存在显著差异。
