The present study was conducted to assess the monthly variations of total lipids content and some biological parameters of rock oyster in the Northern coasts of the Gulf of Oman (Iranian coast) from October 2017 until March 2018 in relation to environmental conditions. According to the results, the maximum and minimum lengths were recorded in December and February, respectively. The highest amounts of weight, dry and wet weight, and condition index were recorded in autumn. There was also a significant difference between the months and the regions for these parameters (p < 0.05). The highest amount of total lipids was observed in March (3.1±1.84) with a significant difference relative to October and November and the lowest amount one was observed in October (2.15±1.6). Also, there was a significant relationship between the total lipids and the temperature. Moreover, there were higher amounts of total lipids in Saccostrea cucullata in winter compared to those in autumn. In general, one of the reasons for the differences in length, weight and total lipids at different stations over different months can mainly be explained by the reproduction season, nutritional conditions, and environmental factors such as temperature and salinity.

阿曼湾北部海岸岩牡蛎（Saccostrea cucullata）总脂质含量和一些生物学参数的月变化

本研究旨在评估 2017 年 10 月至 2018 年 3 月阿曼湾北部海岸（伊朗海岸）的岩石牡蛎总脂质含量和一些生物参数与环境条件相关的每月变化。根据结果​​，最大和最小长度分别记录在 12 月和 2 月。秋季的体重、干湿重和状况指数最高。这些参数的月份和区域之间也存在显着差异（p < 0.05）。3 月份观察到的总脂质量最高（3.1±1.84），与 10 月和 11 月相比有显着差异，10 月份观察到的最低量（2.15±1.6）。还，总脂质与温度之间存在显着关系。此外，与秋季相比，Saccostrea cucullata 冬季的总脂质含量更高。总的来说，造成不同站点不同月份体长、体重和总脂质差异的原因之一主要可以用繁殖季节、营养条件和温度、盐度等环境因素来解释。
