为了描述海洋条件和飞鱼捕获量之间的短期关系，并使弗洛雷斯海潜在渔场的空间格局形象化，使用了海面温度、叶绿素a浓度、捕捞深度和绝对地转流的遥感卫星图像以及捕获量数据。结果表明，飞鱼单位努力渔获量（CPUE）最高的海区为SST 27.5-29.5 °C，叶绿素a含量0.25 ~ 0.70 mg. m-3，流速为25.0 ~ 42.5m. s-1。捕捞深度位置与CPUE无显著相关性。三个优选的海洋学范围提供了一个很好的指标，空间探测潜在的飞鱼渔场，特别是在旺季。预测的潜在捕鱼区位于塔卡拉西南部沃茨，约东经118°45度至119°40度，南纬5°30度至6°10度，并得到捕鱼数据的证实。潜在渔场可能与海洋结构的出现相对应，例如上升流和锋区，这些结构可能是鱼群集中的原因。这项简短的描述性研究表明，这些发现提供了一些初步的结果，在弗洛雷斯海的飞鱼渔场。
To describe the short term relationship between oceanographic conditions and flying fish catches and to visualize a spatial pattern of potential fishing grounds in the Flores sea, remotely sensed satellite images of sea surface temperature (SST), chlorophyll-a concentration, fishing depth and absolute geostrophic current together with catch data were used. Results indicated that the highest flying fish catch per unit efforts (CPUEs) occurred in areas of SST 27.5-29.5 °C, chlorophyll-a 0.25 0.70 mg. m -3 and current velocities 25.0 42.5 m. s -1 . The fishing depth locations have no significant correlation with the CPUEs. The three preferred oceanographic ranges provided a good indicator for spatially detecting the potential flying fish fishing grounds particularly in the peak season. The predicted potential fishing areas were located in the southwestern Takalar waters approximately 118°45‟E-119°40‟E and 5°30‟S-6°10‟S and were confirmed by the fishing data. It is likely that the potential fishing grounds correspond to the occurrence of the oceanographic structures such as upwelling and frontal zones which may be responsible for concentrating the fish schools. This short descriptive study suggests that these findings provide some preliminary results on the flying fish fishing grounds in the Flores Sea.
