In order to manage blue swimming crabs in Pangkajene Kepulauan, management measures are required. Since the environment which affects the abundance of the blue swimming crab varies seasonally, it is necessary to take into account the seasonal nature with the aim of developing a management strategy. The objectives of this study are to define the abundance of and fishing season of blue swimming crabs in the Pangkajene Kepulauan waters, South Sulawesi, Indonesia. The fishing season was analysed using seasonal index analysis, while fish abundance was analysed by means of Equilibrium-Schaefer. The result of this study demonstrated that fishermen allocate their fishing gear all year, although the fish catch is seasonal. Based on analysis of the result, the fishing season for the blue swimming crabs is short. The peak fishing season starts in May and finishes in June. However, in order to enable their families to earn a living, fishermen operated their fishing gear throughout the year. As a result, both catch landing and effort were close to maximum sustainable yield (MSY). In order to reduce fishing pressure, it is necessary to reduce fishing gear and have a seasonal arrangement regarding fishing gear allocation.
为了管理庞卡杰内群岛的蓝蟹,需要采取管理措施。由于影响蓝蟹数量的环境随季节变化,有必要考虑季节性因素,以制定管理策略。本研究的目的是确定印度尼西亚南苏拉威西省庞卡杰内群岛海域蓝蟹的数量和捕捞季节。使用季节指数分析来分析捕捞季节,而通过平衡-谢弗模型来分析鱼类数量。本研究结果表明,尽管渔获量具有季节性,但渔民全年都在配置渔具。根据结果分析,蓝蟹的捕捞季节较短。捕捞旺季从5月开始,6月结束。然而,为了维持家庭生计,渔民全年都在操作渔具。结果,渔获上岸量和捕捞努力量都接近最大可持续产量(MSY)。为了减轻捕捞压力,有必要减少渔具数量,并对渔具配置进行季节性安排。
