Come join us for a discussion on the exploitation of mesopelagic fish, a coveted pool of marine resources, filled with unknowns, uncertainties, opportunities and risks. The Ocean Twilight Zone, a fascinating part of the ocean hosting some of the world's most bizarre-looking and prolific organisms, is key to carbon sequestration and food webs supporting commercially valuable fisheries. The increasing commercial interest for harvesting mesopelagic fish to meeting growing demand for aquaculture feed and nutraceuticals, along with the lack of institutional arrangements to protect high seas resources, highlights the needs for the global community to understand intriguing trade-offs and necessary conditions for sustainable exploitation. With natural-sciences considerations thus far dominating these discussions, we invite you to join us for an interactive 2-hour webinar that draws from lessons learned, past successes and failures that are key to shaping management and governance paths forward.
