Abstract

Fishery is one of the most impacting human activities and is responsible for habitat loss in marine systems. While the effects of large-scale fisheries have been largely investigated, impacts of small-scale fisheries (SSF) on seafloor integrity are more often assumed than quantitatively investigated. We carried out a literature review at global scale, resulting in 19 studies with quantitative data on sessile benthic bycatch and only one documenting habitat loss driven by SSF. We also conducted a fine-scale assessment within a Mediterranean partially protected area (PPA). Results showed that 513 m² of the Posidonia oceanica meadow are removed annually by local SSF within the PPA, considering bycatch, fishing effort, and shoot density. Knowledge on fishing effort and fine-scale mapping is critical to assess habitat loss, suggesting the need for specific recommendations for eco-sustainable local fisheries.

生境丧失与小型渔业：一个有争议的问题

渔业是影响最大的人类活动之一，是海洋系统生境丧失的罪魁祸首。大规模渔业的影响在很大程度上已得到研究，但小型渔业（SSF）对海底完整性的影响更多的是假设而非定量研究。我们在全球范围内进行了文献综述，结果有 19 项研究提供了无柄底栖副渔获物的定量数据，只有一项研究记录了 SSF 造成的生境损失。我们还在地中海部分保护区（PPA）内进行了精细评估。结果表明，考虑到兼捕渔获物、捕捞强度和笋密度，PPA 内每年有 513 平方米的 Posidonia oceanica 草甸被当地 SSF 清除。有关捕捞量和精细绘图的知识对于评估栖息地损失至关重要，这表明有必要为生态可持续的当地渔业提出具体建议。

期刊介绍： Marine Ecology publishes original contributions on the structure and dynamics of marine benthic and pelagic ecosystems, communities and populations, and on the critical links between ecology and the evolution of marine organisms. The journal prioritizes contributions elucidating fundamental aspects of species interaction and adaptation to the environment through integration of information from various organizational levels (molecules to ecosystems) and different disciplines (molecular biology, genetics, biochemistry, physiology, marine biology, natural history, geography, oceanography, palaeontology and modelling) as viewed from an ecological perspective. The journal also focuses on population genetic processes, evolution of life histories, morphological traits and behaviour, historical ecology and biogeography, macro-ecology and seascape ecology, palaeo-ecological reconstruction, and ecological changes due to introduction of new biota, human pressure or environmental change. Most applied marine science, including fisheries biology, aquaculture, natural-products chemistry, toxicology, and local pollution studies lie outside the scope of the journal. Papers should address ecological questions that would be of interest to a worldwide readership of ecologists; papers of mostly local interest, including descriptions of flora and fauna, taxonomic descriptions, and range extensions will not be considered.
