ME003:
Illuminating the twilight zone: Understanding mesopelagic communities, processes, and ecosystem services before potential large-scale resource extraction


Session ID#: 28610

Session Description:
Mesopelagic fish biomass has recently been estimated at 7-10 billion metric tons, an order of magnitude higher than previous estimates, spawning new interest in commercial harvesting of pelagic ecosystems. Within the last year countries such as Norway and Pakistan have issued licenses for fishing the mesopelagic zone. However, we are still in the process of determining mesopelagic diversity, biogeography, food web structure, ecological process rates and production drivers and dynamics. What do we know that informs sustainable fisheries management and what are the major gaps? What ecosystem services are provided by the mesopelagic community and what are the tradeoffs that direct exploitation then presents for management? In this session we invite presentations on mesopelagic communities and processes, particularly presentations that inform our understanding of ecosystem services (e.g. vertical carbon flux, food supply for top predators) that might be impacted by potential fishing efforts.
