“…Previous studies have relied on proxies of stress such as blood stress chemistry (e.g., Brooks et al, 2011;Hyatt et al, 2011) and hormone levels (Barton, 2002), tag and recapture data (e.g., Francis, 1989;Hueter et al, 2006) or satellite and acoustic telemetry (e.g., Holts and Bedrofd, 1993;Hoolihan et al, 2011;Sepulveda et al, 2015;Skomal, 2006). Although the physiological proxies have revealed high inter-specific variability in the response to capture stress (Frick et al, 2010;Hyatt et al, 2011;Mandelman and Skomal, 2009;Marshall et al, 2012), very few studies have correlated these stress values to actual animal outcomes, and the ability of these proxies to predict post-release mortality or sub-lethal effects is largely untested. Tag-recapture studies require large sample sizes of frequently caught species and may take years of recapture data collection to provide an assessment (Hueter et al, 2006).…”

“…Studies of blood chemistry of sharks have revealed that capture stress can manifest itself in changes in La − (Hoffmayer and Parsons, 2001;Moyes et al, 2006;Hyatt et al, 2012), hematocrit (Brill et al, 2008;Marshall et al, 2012), HCO 3 Hyatt et al, 2012), K+ (Mandelman and Farrington, 2007;Frick et al, 2010;Marshall et al, 2012), Ca 2+ , Na + (Marshall et al, 2012), and pH (Hoffmayer and Table 1. Environmental metrics were temperature and dissolved oxygen; the behavioral metric was fight time; and biochemical metrics were lactate concentration, acidity (pH), and partial pressure of carbon dioxide (pCO 2 ).…”

“…Efforts have been made to link perturbations in blood biochemistry to animal stress and mortality resulting from capture (Wells et al, 1986;Skomal, 2006;Hyatt et al, 2012). Exhaustive exercise such as fighting on a line, typically causes a marked decrease in blood pH (acidemia) resulting from metabolic (increasing H + as indicated by rising blood lactate and decreasing blood bicarbonate) and respiratory (increasing partial pressure of carbon dioxide [pCO 2 ]) acidoses (Wood, 1991;Milligan, 1996;Kieffer, 2000;Skomal and Bernal, 2010;Skomal and Mandelman, 2012).…”

Abstract-The blacktip shark (Carcharhinus limbatus) is the most commonly captured species in the Florida recreational shark fishery. We aimed to quantify the postrelease mortality of blacktip sharks and to determine whether hook type (circle or J) had any impact on survival. We measured capture variables (e.g., fight time, animal condition, etc.), blood gas analytes, and finescale behavior obtained by using acceleration data loggers for blacktip sharks (n=31) caught on rod and reel by recreational fishermen. Mortalities (n=3; 9.7%) all occurred within 2 h after release. Surviving sharks were monitored for 7 to 72 h (mean: 30 h [standard deviation (SD) 22]) and behaviorally recovered from capture within 11 h (SD 2.6), although larger individuals recovered faster. Hook type did not affect where a shark was hooked, animal condition, the likelihood of hook removal, or recovery time. We found relatively low levels of mortality for blacktip sharks caught in the recreational fishery that were kept in the water and had not sustained serious injuries.

“…In the future, the effects on blood biochemistry (as an indicator of stress response, morbidity, etc.) could also be examined in relation to postcapture behavior and survivorship in comparison with other capture methods (e.g., Hyatt et al, 2012;Hyatt et al, 2016). Currently, strong evidence supports the continued use and development of the poker-and-hook method and its application in research.…”

Abstract-We developed an alternative capture-and-release method for sharks using a simple poker-andhook tool for divers to quickly capture nurse sharks (Ginglymostoma cirratum) entering the intake canal of a nuclear power plant in Florida. The capture technique consists of using a short metal rod (poker) with a barbless J-hook (size 10/0) to snag the base of a shark's tail (caudal peduncle), then safely hauling the individual into a boat by the buoy line that has been hooked to its tail. We captured 20 nurse sharks ranging from 11.8 to 80.3 kg, and 9 individuals were monitored over time. Six sharks were released into the canal and 3 sharks were put in an open tank for 23-24 days for daily observations. All hook wounds resulting from this technique were assessed between 9 and 42 days, and no ill effects were observed throughout the study period. The capture method caused a small superficial wound to the caudal peduncle that averaged 11.3 mm 2 (standard deviation 8.7; n=23). Wound closure was observed after 9 days and re-epithelialization was almost complete (or the wound had completely healed) between 22 and 42 days. Landing nurse sharks this way is less traumatic than traditional methods (e.g., angling, netting). This study provides preliminary information on, and validates, the use of this tool as an efficient and less invasive capture method than traditional methods and as a method that could be applied to broader areas of shark research.
