High survivorship after catch-and-release fishing suggests physiological resilience in the endothermic shortfin mako shark (Isurus oxyrinchus)

Abstract: We used satellite tags and blood based analyses to examine the impacts of catch and release angling on the shortfin mako shark. We report high survivorship seemingly unaffected by fight time or physiological stress and recommend that circle hooks should be used to reduce physical damage to these sharks.

“…Maturity in males was assessed following [13]. Great hammerheads that were deemed to be in good condition (i.e., active and responsive, little or no visible external damage, [14]) were fitted with three tags: a conventional dart tag (Floy) and two satellite tags. Smart position and temperature transmitting tags (SPOT6, Wildlife Computers) were attached to the dorsal fin.…”

“…Recent research involving coastal and pelagic sharks (primarily Carcharhinid species) has also evaluated that the survival of sharks in response to capture have also found high variability in survival rates (see reviews by Skomal and Bernal 2010;Skomal and Mandelman 2012), but the vast majority of this work has involved commercial fishing interactions and not recreational angling (Molina and Cooke 2012;Gallagher et al 2015). The growing realization that sharks could be negatively affected by CR fisheries interactions has spawned a handful of studies focusing on recreational angling (e.g., Campana et al 2006;Robbins et al 2013;Danylchuk et al 2014;French et al 2015), including some human dimensions work (Babcock 2009;Gallagher et al 2015;McClellan Press et al 2015), but many significant gaps in knowledge and research remain. Mortalities from recreational fishing are a form of fishing mortality, and thus they are important for stock assessments and fisheries management plans, although this information is not always available [i.e., the Southeast Data Assessment and Review; SEDAR (e.g., Atlantic sharpnose shark, blacktip shark, bonnethead shark) NOAA Fisheries 2006; Shiffman and Hammerschlag 2016a].…”

“…Such point-of-care field devices have been used in elasmobranchs (e.g. Awruch et al, 2011;French et al, 2015) and have been validated for lactate in school (Awruch et al, 2011) and shortfin mako shark (French et al, 2015). However, these instruments are not precise and we used values for relative comparisons; absolute values should be interpreted with caution (see Stoot et al, 2014).…”
