The relationships of size and weight of otoliths with length and weight and mass of fish were estimated for four ponyfish species (Aurigequula fasciata; Deveximentum ruconius; Nuchequula gerreoides and Photopectoralis bindus) from the Persian Gulf and the Oman Sea. The results revealed some significant relationships (p < 0.05) between otolith length and width vs. fish length, and otolith weight vs. fish weight in all four species (r² > 0.71). The higher coefficient of determination (r²) for FW-OWE relationships in studied ponyfish species suggested higher correlation between fish weight and otolith weight than fish length—otolith size relationships. There is no previous report on size-weight relationships of fish and otolith measurments among four studied ponyfish species. These estimated equations can be used in back-calculation studies, especially for these four ponyfishes as the dominant prey for piscivorous predators in their habitats.

的尺寸和重量与长度和重量和鱼的质量耳石的关系估计四个ponyfish物种（Aurigequula  fasciata ; Deveximentum ruconius ; Nuchequula  gerreoides和Photopectoralis  bindus）从波斯湾和阿曼海。结果揭示了 所有四种物种的耳石长度和宽度与鱼的长度以及耳石重量与鱼的重量之间的一些显着关系 ( p < 0.05) ( r ²  > 0.71)。较高的决定系数 ( r ²) 对于研究的马鱼物种中的 FW-OWE 关系，表明鱼重量和耳石重量之间的相关性高于鱼的长度-耳石大小关系。之前没有关于四种研究过的马鱼物种中鱼类和耳石测量的大小重量关系的报告。这些估计的方程可用于反算研究，特别是对于这四种小马鱼作为其栖息地中食肉性捕食者的主要猎物。
