摘要

摘要: 自1998年“捕捞降低海洋食物网”概念首次提出以来，渔获物平均营养级（Mean trophic level of fisheries landings,MTL）广泛用于评估捕捞活动对生态系统完整性的影响，并指导管理机构的政策制定。近年来研究表明，掌握MTL的潜在变化机制对于以MTL作为渔业可持续性指标至关重要。根据联合国粮农组织FAO提供的渔获统计数据，结合Fishbase提供的相关鱼种营养级，本文探讨了全球三大洋14个FAO渔区MTL的变化趋势，并进一步分析不同MTL变化趋势下高营养级鱼种和低营养级鱼种渔获量的变动情况。研究表明， MTL呈上升和回升状态均可能伴随着低营养级鱼种渔获量的下降。此外，通过观察营养级高于3.25鱼种的MTL以区分“捕捞降低海洋食物网”和“捕捞沿着海洋食物网”现象需考虑生态系统的群落结构和开发历程。利用渔获物平均营养级评价渔业可持续性必须综合考虑高营养级和低营养级鱼种，以及群落结构和开发历程的掩盖效应。

Abstract: Since the concept of "fishing down marine food webs" was first proposed in 1998, mean trophic level of fisheries landings (MTL) has become one of the most widely used indicators to assess the impacts of fishing on the integrity of marine ecosystem and guide the policy development by many management agencies. Recent studies suggest that understanding underlying causes for changes in MTL is vital for an appropriate use of MTL as an indicator of fishery sustainability. Based on the landing data compiled by Food and Agriculture Organization (FAO) and trophic information of relevant species in Fishbase, we evaluated MTL trends in 14 FAO fishing areas and analyzed catches of upper and lower trophic level groups under different trends of MTL and found that both the cases of a recovered MTL trend and a generally increasing MTL trend could be accompanied by decreasing catches of lower trophic level species. Further, community structure and exploitation history should be considered in using MTL after excluding species with trophic levels lower than 3.25 to distinguish "fishingthrough" from "fishing-down". We conclude that MTL used as an indicator to measure fishery sustainability can benefit from a full consideration of both upper and lower trophic level species and masking effects of community structure and exploitation history.
