Abstract

Information on effects of fisheries capture on the physiology and post-release condition of sharks is urgently needed to design and implement effective fisheries management plans for shark stocks around the world, but obtaining data on post-release condition in the wild is very difficult. We used a controlled setting to subject Port Jackson sharks (Heterodontus portusjacksoni) and gummy sharks (Mustelus antarcticus) to varying durations of gill-net and longline capture stress for up to 360 min and monitored their condition via repeated blood sampling during a subsequent 72-h recovery period.
