“…Circle hooks may produce a different retrieval presentation than J hooks; however, additional experiments will be required to test whether foraging behavior differs as a result of hook configuration. Even so, our results are consistent with other reports that suggest greater capture efficiencies with J hooks for red drum Sciaenops ocellatus (Aguilar et al 2002), striped bass Morone saxatilis (Lukacovic 2000), largemouth bass Micropterus salmoides (Cooke et al 2003b), and walleyes Sander vitreus (Jones 2005). Collectively, these results and those of our study indicate that capture efficiency is generally lower when circle hooks are used.…”

“…In our study, muskellunge were more often hooked in the corner of the mouth, upper jaw, or lower jaw and exhibited minimal bleeding regardless of gear configuration, presumably because of their foraging behavior. Indeed, fish that rely on inertial suction feeding, such as largemouth bass, have greater hooking depths, higher injury rates, and higher mortality (Cooke et al 2003b). However, muskellunge may experience a different outcome if anglers use a different fishing style or strategy.…”

Abstract.-Strict harvest regulations and a strong catchand-release ethic among recreational anglers of muskellunge Esox masquinongy have led to interest in developing strategies for reducing injury and mortality of released fish. With many anglers using live baitfish to capture muskellunge, the use of circle hooks may reduce deep hooking and hence mortality. We contrasted the performance of circle hooks and J-style aberdeen hooks when capturing juvenile muskellunge with actively fished live baitfish. The J hooks performed better than circle hooks in terms of capture efficiency. The J hooks were more efficient at hooking muskellunge than were circle hooks, but landing efficiency was similar between the two types. Interestingly, injury was judged to be low regardless of hook type. Neither anatomical hooking location nor hooking depth differed significantly between fish captured on J and circle hooks. No fish were hooked in potentially lethal locations (e.g., gullet or eye) during the use of either hook type. Ease of hook removal did not differ between hook types, and hooks were generally categorized as easy to remove. Bleeding was considered minor and did not differ between hooks. We observed no initial or delayed mortality for fish captured on J or circle hooks. Given that J hooks have a higher muskellunge capture efficiency and that the use of circle hooks did not provide any compelling conservation benefits, anglers will probably continue to use J hooks and avoid circle hooks. Nonetheless, use of circle hooks could be advantageous for other fishing styles (e.g., still fishing, where baitfish are often swallowed), other species, or different sizes of muskellunge.

“…Siepker et al (2007), in a review of the impacts of catchand-release fishing, argued that hooking is a primary source of capture-related injury that can potentially cause mortality in black bass. For Cooke et al (2003), individuals that suffered life-threatening injuries were typically hooked deeply in a vital organ or tissue (i.e. heart, gullet, gill arch), exhibited substantial bleeding, and were caught with hooks that were difficult to remove.…”

“…In this study, seven individuals suffered some kind of bleeding, and four of these died. In a study of catch-and-release fishing of largemouth bass, ~20% suffered some kind of hemorrhage at the time of capture, but less than 6% died (Cooke et al 2003). Therefore, hook location and the occurrence of bleeding appear as the most influential variables in determining the probability of death of a hooked and released fish (Millard et al 2005;Broadhurst et al 2012 b), including the size of the individual (Millard et al 2005;Hall et al 2009;Alos 2009).…”

“…In the USA, Canada and Australia, studies show low mortalities for freshwater fish released following capture. Cooke et al (2003) and Pope and Wilde (2004) reported <7% mortality for largemouth bass (Micropterus salmoides Lacépède). Similarly, Muoneke (1992) encountered <10% mortality for white crappie (Pomoxis annularis Rafinesque) and spotted bass (Micropterus punctulatus Rafinesque), while Dunmall et al (2001) reported negligible mortality for smallmouth bass (Micropterus dolomieu Lacépède).…”

Peacock bass mortality associated with catch-and-release sport fishing in the Negro River, Amazonas State, Brazil

Sport fishing for peacock bass Cichla spp. in the Brazilian Amazon has increased in popularity and attracts anglers who generate significant economic benefits in rural regions. The sustainability of this fishery is partly dependent on the survival of fish caught through catch-and-release fishing. The objective of this work was to investigate, hooking mortality of Cichla spp., including speckled peacock bass (C. temensis Humbolt), butterfly peacock bass (C. orinocensis Humbolt), and popoca peacock bass (C. monoculus Agassiz) in the basin of the Negro River, the largest tributary of the Amazon River. Fish were caught at two different sites using artificial lures, transported to pens anchored in the river and monitored for 72 hours. A total of 162 individual peacock bass were captured and hooking mortality (mean % ± 95% confidence intervals) was calculated. Mean mortality was 3.5% (± 5.0), 2.3% (± 3.5) and 5.2% (± 10.2) for speckled peacock bass, butterfly peacock bass, and popoca peacock bass, respectively. Lengths of captured fish ranged from 26 to 79 cm (standard length), however, only fish under 42 cm died. This research suggests that catch-and-release sport fishing of peacock bass does not result in substantial mortality in the Negro River basin. KEYWORDS: Artificial bait, Cichla spp., Fisheries assessment Mortalidade de tucunaré associada à pesca esportiva do pesque e solte no rio Negro, Amazonas, Brasil RESUMO A pesca esportiva de tucunarés Cichla spp., na Amazônia brasileira, aumentou em popularidade nos últimos anos e tem atraído pescadores esportivos que geram benefícios econômicos para essa região. Entretanto, a sustentabilidade dessa pescaria depende em parte da sobrevivência dos peixes capturados por meio da prática do pesque e solte. O objetivo deste trabalho foi avaliar a mortalidade de Cichla spp., incluindo o tucunaré paca (C. temensis Humbolt), o borboleta (C. orinocensis Humbolt) e o popoca (C. monoculus Agassiz) em dois locais na bacia do rio Negro, o maior tributário do rio Amazonas. Os peixes foram capturados por variados tipos de iscas artificiais e posteriormente monitorados em viveiros construídos no próprio rio por 72 horas. Um total de 162 tucunarés foi capturado, e as mortalidades (% ± intervalo de confiança 95%) foram calculadas. A mortalidade foi 3,5% (± 5,0), 2,3% (± 3,2) e 5,2% (±10,2) para o paca, o borboleta e o popoca, respectivamente. O comprimento padrão dos peixes capturados variou de 26 a 79 cm, mas apenas os peixes menores até 42 cm morreram. A pesquisa sugere que a pesca esportiva não causou substancial mortalidade na população de Cichla spp. na bacia do rio Negro.
