When spatial fishing data is fed into systematic conservation planning processes the cost to a fishery could be ensured to be minimal in the zoning of marine protected areas. We used vessel monitoring system (VMS) data to map the distribution of prawn trawling and calculate fishing intensity for 1-ha grid cells, in the Kosterhavet National Park (Sweden). We then used the software Marxan to generate cost-efficient reserve networks that represented every biotope in the Park. We asked what were the potential gains and losses in terms of fishing effort and species conservation of different planning scenarios. Given a conservation target of 10 % representation of each biotope, the fishery need not lose more than 20 % of its fishing grounds to give way to cost-efficient conservation of benthic diversity. No additional reserved area was needed to achieve conservation targets while minimizing fishing costs. We discuss the benefits of using VMS data for conservation planning.
当将空间渔业数据输入到系统保护规划流程中时,可以确保在划定海洋保护区的分区时,渔业的成本最小化。我们使用船只监控系统 (VMS) 数据来绘制对虾拖网捕捞的分布情况,并计算了每 1 公顷网格单元的捕捞强度,该数据来自于瑞典的科斯特哈维特国家公园。然后,我们使用 Marxan 软件生成具有成本效益的保护区网络,以代表公园中的每一种生物群落。我们询问了不同规划方案在捕捞努力和物种保护方面的潜在收益和损失。如果保护目标是代表每个生物群落的 10%,那么为了实现具有成本效益的底栖生物多样性保护,渔业不必放弃超过 20%的渔场。在最小化捕捞成本的同时,不需要额外的保护区来实现保护目标。我们讨论了使用 VMS 数据进行保护规划的好处。
