Abstract

This study explored the anthropogenic stressors of a coral habitat and predicted the role of a proposed MPA around coral habitat on biodiversity conservation. The study was conducted in the Saint Martin's Island which is located in the south east coastal area of Bangladesh. Data on anthropogenic stressors were collected through intensive stakeholder survey and the role of MPA in biodiversity conservation was explored by utilizing Allometric Trophic Network model. This study identified about 16 anthropogenic stressors for the coral reef ecosystem. Increasing fishing pressure significantly reduced the species biomass while reduced fishing pressure increased the biomass of species. Biomass of the species in the system with no fishing area increased significantly (3–6%) while compared with the species biomass of an area without fishing restriction. Our simulations found that imposing fishing restriction in an exploited system significantly improve the species standing stock. Our model outputs suggest that declaration of MPA is beneficial for conservation of biodiversity. However, for sustainable implementation of conservation initiatives a proper management framework is necessary integrating diverse stakeholders.

海洋保护区在生物多样性保护中的作用建模
本研究探讨了珊瑚生境的人为压力源,并预测了珊瑚生境周围海洋保护区对生物多样性保护的作用。这项研究是在位于孟加拉国东南沿海地区的圣马丁岛进行的。通过密集的利益相关者调查收集人为压力源数据,利用异速生长营养网络模型探讨海洋保护区在生物多样性保护中的作用。这项研究确定了大约16个人为的珊瑚礁生态系统压力源。增加捕捞压力会显著降低物种生物量,而降低捕捞压力则会增加物种生物量。无渔捞区的物种生物量较无渔捞区的物种生物量显著增加(3-6%)。我们的模拟发现,在已开发的系统中实施捕捞限制可显著改善物种存量。我们的模型结果表明,宣布海洋保护区有利于生物多样性的保护。然而,为了可持续地实施保护措施,需要一个适当的管理框架,将不同的利益相关者结合起来。

期刊介绍: The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
