The Mohan Shark and Fish Ecology Laboratory conducts research to better understand the ecology and biology of sharks and fishes across wide spatial scales. Our research has direct applications to fisheries management and conservation. We utilize interdisciplinary techniques, laboratory experimentation and quantitative analysis to advance knowledge in fisheries ecology through hypothesis testing. Our collaborative research consists of characterizing fish life histories including age and growth, habitat use, migration patterns, population connectivity, and feeding dynamics on local, regional and ocean-basin scales. Current research topics include hard part geochemistry of fish and sharks, stable isotope ecology, acoustic and satellite telemetry, and development of bycatch reduction devices. We partner with stakeholders to investigate the influence of recreational catch-and-release fishing on fish health and survival and develop technology to reduce shark bycatch.
