Short-term hooking mortality of tailor (Pomatomus saltatrix) in Western Australia and the impact on yield per recruit

Mortality impact of recreational angling techniques and hook types on Trachynotus ovatus (Linnaeus, 1758) following catch-and-release

“…These results indicate that T. ovatus died soon after capture and that the containment period had a minimal effect in PRM. The anatomical hooking location was the most important PRM factor and incidence of deep hooking was highly correlated with high percentages of PRM (Ayvazian et al, 2002;Aalbers et al, 2004;St John and Syers, 2005;Broadhurst et al, 2005;Butcher et al, 2006;Grixti et al, 2008;Alós et al, in press). According to our results, the incidence of deep hooking (26.6%) was similar to PRM (24.1%).…”

“…The anatomical region where the hook pierces the fish has traditionally been considered the most important factor affecting PRM (Bartholomew and Bohnsack, 2005). Fish hooked in deep locations (i.e., stomach, oesophagus, or gills) was less likely to survive C&R than those hooked in more shallow locations (i.e., lip or mouth) (Ayvazian et al, 2002;Aalbers et al, 2004;St John and Syers, 2005;Broadhurst et al, 2005;Butcher et al, 2006;Grixti et al, 2008;Alós et al, in press). It has been suggested that deep-hooking incidence was dependent on several factors, including fish size (Grixti et al, 2007;Alós et al, 2008, in press), hook type (Cooke and Suski, 2004), hook size Grixti et al, 2008;Alós et al, 2008, in press), or angling technique (passive vs. active) (Grixti et al, 2007).…”

Factors Affecting Catch‐and‐Release Mortality of Bluefish

“…For instance, Ayvazian et al (2002) reported 95% survival after 2 h, Malchoff (1995) observed 87.6% survival up to 3 d postrelease, and Williams (1995) reported 97% survival in jawhooked fish but only 68.7% survival for gut-hooked fish observed for 7 d. Although postrelease mortality in bluefish appears to be relatively low (compared with rates reported by Muoneke and Childress [1994] and Bartholomew and Bohnsack [2005]), previous studies may have underestimated total mortality associated with capture and release because postrelease observation times were short.…”

“…Based on a meta-analysis of 53 catch-and-release studies, hooking location, use of natural bait, depth of capture, elevated water temperature, and extended playing and handling times were significantly associated with increased hooking mortality rates across species (Bartholomew and Bohnsack 2005). In bluefish, the location of the hook wound is an important determinant of catch-and-release mortality (Ayvazian et al 2002). Adult bluefish hooked in the gut or gills and observed for 2 h postrelease were concluded to have died because of the increased handling time required to remove the hook from the fish (Ayvazian et al 2002).…”

Adult bluefish hooked in the gut or gills and observed for 2 h postrelease were concluded to have died because of the increased handling time required to remove the hook from the fish (Ayvazian et al 2002). Bait type, fish size, and water temperature had no detectable effect on postrelease survival of bluefish monitored for 3 d (Malchoff 1995).…”
