Applying Physiology to Conservation and Fisheries Management
Session Organizers: Christine L. Madliger, Graham D. Raby, Steven J. Cooke
Date: January 5, 13:20 – January 6, 11:40
Location: Salon G
The management of fisheries can benefit from a mechanistic understanding of the effects of stressors on individual fishes, populations, and ecosystem functioning. The field of conservation physiology involves a diverse set of tools that can link individual performance to population dynamics, provide information on sex and reproductive status, offer insight into adaptive potential, and assess and compare stocking and restoration strategies. This session will showcase how research using a variety of physiological techniques and traits (e.g., respiratory physiology, transcriptomics, genetics, stress physiology) can help determine vulnerability to stressors, local adaptation, drivers of fish distribution and abundance, and how to better contain invasive species. Most importantly, we will explore how investigating the mechanisms underlying behaviour, performance, and fitness through the collection of physiological data could help policymakers ensure fish and fish habitat are managed sustainably.
