Since the early 1990s, sea urchin landings, catch per unit effort, and number of harvesters have decreased dramatically. Management measures to date have been ineffective in stemming the decline. To explore new management tools, the sea urchin industry and state regulators established conservation areas, previously productive habitats that are closed to harvesting, to determine how long it will take for stocks to recover once fishing mortality rates are reduced. In this study, researchers will contrast conservation areas with adjacent fished control areas to characterize rates of recovery and resilience of overharvested urchin populations and associated changes to algal communities. These studies could provide the urchin industry with information on how to harvest the resource sustainably.
