Exploring fisheries dynamics according to different quota governance mechanisms: application to the Bay of Biscay sole fishery

Creator:: Bellanger, Manuel, Merzereaud, Mathieu, Guyader, Olivier, and Macher, Claire
Abstract:: Integrating governance mechanisms into bio-economic modeling tools is a key challenge for the assessment of fisheries management plans. Impact assessments are carried out without considering real management options and institutional context. Only fishing mortality changes and their impact on fish stocks are considered. The Bay of Biscay sole fishery offers...

Indicators for Ecosystem Externalities in Fishing

Creator:: Ravn-Jonsen, Lars, Andersen, Ken H., and Vestergaard, Niels

We use simulations from a size-spectrum ecosystem model to investigate the ecosystem externality created by fishing of multiple species. The model is based upon general ecological principles and is calibrated...

The Dynamic Role of Sablefish in a Mutlispecies, Multigear IFQ Fishery

Creator:: Holland, Dan and Steiner, Erin
Abstract:: Individual fishing quota (IFQ) systems are typically expected to increase the profitability of a fishery and improve sustainability by ensuring catches remain within quotas. They can also have important distributional and ecological implications that result from shifts in catch and effort between different gears, regions, and habitats. In multispecies fisheries...

Abstract:: Ecosystem services (ES) provide a pathway to connect ecosystem processes to human well-being. Ecosystem-based fisheries management can utilize the ecosystem service framework to assess trade-offs of actions such as restoration and gear restrictions, or environmental changes such as ocean acidification and warming, and sea level rise. However, due to a...
