摘要

2005 年至 2008 年 ICES 分部 VIIe-h 中的船舶监测系统 (VMS) 数据用于评估英吉利海峡西部及其周围捕鱼活动的分布和强度,英吉利海峡是地球上使用最密集的海域之一。对英国大型(415 m 长)渔船船队的分布进行了分析,并发现了明显的特定渔具活动的时间和空间差异。移动底层齿轮在研究区域具有最高的强度和最广泛的活动分布,因此可能会产生最广泛的生态系统影响。两个拟议的渔业关闭的潜在影响;描述了一个计划中的波浪能测试设施(Wave Hub)和一个候选的近海海洋保护区(Haig Fras)。地图表明,如果将移动底层渔具船队排除在这些提议的关闭之外,它们几乎不会受到影响,但如果将静态渔具船队排除在外,这可能会导致某些船只流离失所,增加对其他岩石地和其他渔民的捕捞压力。通过使用高分辨率的特定渔具活动数据,可以改进对渔业迁移影响的预测。这项研究表明,VMS 可以提供此类数据的宝贵来源,前提是渔业管理人员和科学家可以获得渔具信息。 Vessel Monitoring System (VMS) data from 2005 to 2008 in ICES Divisions VIIe-h were used to assess the distribution and intensity of fishing activity in and around the western English Channel, one of the most intensively used marine areas on the planet. The distribution of the UK fleet of large (415 m length) fishing vessels was analysed and clear gear-specific temporal and spatial differences in activity were found. Mobile demersal gears had the highest intensity and widest distribution of activity in the study area, and so might be expected to have the most widespread ecosystem-level impacts. The potential effects of two proposed fisheries closures; a planned wave energy testing facility (Wave Hub) and a candidate offshore Marine Protected Area (Haig Fras) are described. Maps indicate that mobile demersal gear fleets would be little affected if they were excluded from these proposed closures, but if the static gear fleets were excluded this would likely result in displacement of certain vessels, increasing fishing pressure on other rocky grounds and other fishers. Predictions concerning the effects of fisheries displacement can be improved through the use of high-resolution gear-specific activity data. This study shows that VMS can provide an invaluable source of such data, provided that gear information is made available to fisheries managers and scientists.
