Discards, hooking, and post-release mortality of porbeagle (Lamna nasus), shortfin mako (Isurus oxyrinchus), and blue shark (Prionace glauca) in the Canadian pelagic longline fishery (2016, background): “Several studies have reported increased lactate levels in highly stressed sharks and teleosts, but were not able to measure any subsequent mortality in the assayed individuals under natural conditions (Moyes et al., 2006; Frick et al., 2010; Heberer et al., 2010; Gallagher et al., 2014).”
Vulnerability of oceanic sharks as pelagic longline bycatch (2014, background): “…of individuals to the process of hook-and-line capture can vary highly among species (Mandelman and Skomal, 2009; Gallagher et al., 2014b), leading to differences in acute (maintenance of physiological equilibrium, Frick et al., 2010) and long-term (survival and reproductive fitness) consequences.”
Looking beyond the mortality of bycatch: sublethal effects of incidental capture on marine animals (2014, background): “For example, Frick et al. (2010a, 2010b, 2012) found that gummy sharks (Mustelus antarcticus) were highly susceptible to physiological disturbances by both trawl, gill net and longline capture, while Port Jackson sharks (Heterodontus portusjacksoni) did not experience significant physiological…”
