Capture stress and post-capture survival of sharks and other chondrichthyans in fisheries bycatch

The primary aim of this study is to use a laboratory model to identify and understand the effects and consequences of fisheries incidental capture on native sharks and determine their post-release fate, to properly inform programs for their management and conservation. To do this we will obtain data on sharks' tolerance and physiological reaction to capture stress in a controlled setting. This approach also allows monitoring the recovery period after stress exposure. In a second stage of the project, sharks subjected to capture stress in the lab will subsequently be equipped with an ultrasonic transmitter and immediately released into the natural environment. We will thereby determine their post-capture survival and physiological response.
