Seminar Announcement
“Ecosystem based fisheries management (EBFM): the Aegean Sea case study”
Donna Dimarchopoulou
Woods Hole Oceanographic Institution
Wednesday, September 21, 2022
2:30 pm – 3:30 pm
SMAST East, Rooms 101/102
and via Zoom
Abstract:
Shifting marine ecosystems call for holistic management strategies to minimize potential negative impacts of overfishing and other human-induced stressors on habitats and biodiversity, the economy and food security. EBFM requires that decision making should be based not only on the characteristics of particular commercial stocks, but on all components of the ecosystem. Consequently, a complete fisheries management view would require a combination of both conventional single-species approaches and a more holistic consideration of the ecosystem that takes into account the effects of multi-species interactions, environmental parameters and fishing practices. The Ecopath with Ecosim modeling suite has been a widely used tool in the context of EBFM to describe exploited marine food webs and perform temporal and spatial simulations to analyze the impact of fishing activities and environmental drivers on aquatic ecosystems. Single-species stock assessments have revealed the bad status and overexploitation of data-poor Greek stocks, results also corroborated by ecosystem model simulations. Model predictions have indicated that rebuilding of stock biomass is possible with a reduction in total fishing effort combined with the implementation of marine protected areas. Identifying and filling data gaps is needed to reduce uncertainty and increase model performance and predictive capacity, thus facilitating the progress towards such more holistic modeling and management approaches. Here, the basic concepts and terminology of EBFM will be discussed through the case study of the Aegean Sea, Greece, eastern Mediterranean Sea.
