Marine resource stewardship
Ecosystem-based management
Identification of critical habitats and habitat “hot spots”
Knowledge of movements and interactions w/ environment.
Application and development of novel biotelemetry technologies
Marine reserves can help conservation & fisheries sustainability if properly designed habitat use & movements
