Abstract

We identify the main fishing grounds in the Philippines’ maritime Exclusive Economic Zone and track the response of fishing vessels’ activity to tropical cyclones (TCs) during 2012. We use satellite imagery from the National Oceanic and Atmospheric Administration to locate fishing vessels and identify the main fishing grounds. We combine these with data on TCs' speed and trajectory from the International Best Track Archive for Climate Stewardship. We use kernel density functions to identify fishing grounds and Vector Generalized Linear Model and Bayesian Time-Varying Parameter to assess the impact of TC speed on the location of fishing vessels during and after the TC. Our quantifications reveal the overall negative impact of TCs on the number of active boats during and 2 days after the TC. The fishing grounds located within the Sibuyan Sea, Visayan Sea, and Panay Gulf are the most affected areas. Daily reduction in the commercial fishing production in Western Visayas alone for every day a TC passed through was estimated at 7800 tons per day, affecting more than 188,000 families.

热带气旋对菲律宾渔业活动的影响

我们确定了菲律宾海洋专属经济区内的主要渔场，并跟踪了 2012 年期间渔船活动对热带气旋（TC）的反应。我们利用美国国家海洋和大气管理局提供的卫星图像来确定渔船的位置并识别主要渔场。我们将这些数据与国际气候管理最佳轨迹档案中有关热带气旋速度和轨迹的数据相结合。我们使用核密度函数来识别渔场，并使用矢量广义线性模型和贝叶斯时变参数来评估热带气旋速度在热带气旋期间和之后对渔船位置的影响。我们的量化结果显示，在热带气旋期间和之后两天，热带气旋对活跃渔船数量的总体影响是负面的。位于锡布延海、米沙鄢海和帕奈湾的渔场是受影响最严重的地区。据估计，在热带气旋经过的每一天，仅西米沙鄢群岛每天的商业捕鱼产量就会减少 7800 吨，影响到 18.8 万多个家庭。

期刊介绍： This journal provides an international forum for the publication of papers in the areas of fisheries science, fishing technology, fisheries management and relevant socio-economics. The scope covers fisheries in salt, brackish and freshwater systems, and all aspects of associated ecology, environmental aspects of fisheries, and economics. Both theoretical and practical papers are acceptable, including laboratory and field experimental studies relevant to fisheries. Papers on the conservation of exploitable living resources are welcome. Review and Viewpoint articles are also published. As the specified areas inevitably impinge on and interrelate with each other, the approach of the journal is multidisciplinary, and authors are encouraged to emphasise the relevance of their own work to that of other disciplines. The journal is intended for fisheries scientists, biological oceanographers, gear technologists, economists, managers, administrators, policy makers and legislators.
