“…Other studies related to CR mortality performed in Brazil frequently show low percentages of immediate (soon after release) and short-term mortality (<72 h), supporting our results. Examining immediate mortality, Sepulchro et al (2013) found 100% survival of red piranha (Pygocentrus nattereri) for AET shorter than 180 s. When related to short-term mortality, peacock bass (Cichla temensis) kept in a cage for 72 h after CR reported values of 3.5% and 0.55% (Thomé-Souza et al, 2014;Barroco et al, 2018, respectively), 2.3% for C. orinocensis and 5.2% for C. monoculus (Thomé-Souza et al, 2014). However, as these studies were carried out for short-term mortality evaluation, they were not able to quantify the effects of CR on weight and length gain.…”

Catch-and-release (CR) angling has been used to assist management programs seeking to promote the conservation and recovery of some recreational fish stocks by decreasing mortality from fishing. However, without appropriate fish handling, this activity may cause damage and injuries to individual fish, causing mortality. Therefore, CR should be allowed under some circumstances that ensure higher rates of survival to achieve the goals of the conservation measures. Thus, we experimentally tested the CR effects on dourado (Salminus brasiliensis) by comparing caught-and-released fish (CR fish) with uncaught fish (control fish) in a pond and estimating individual mortality rates related to seven air exposure times (AET: 120 s, 240 s, 360 s, 480 s, 600 s, 720 s and 840 s). We also determined a safe limit for fish handling and investigated the length and weight gain variations. We found that an increase in AET affects fish survival and that the limit of handling time for this species was 546 s; after this threshold, the individual probability of death exceeds 5%. The length and weight gain of CR fish did not differ significantly from the control fish. We believe that CR is efficient for S. brasiliensis because it does not significantly impair their organic growth and causes little or no mortality if handling is performed properly; thus, it could be employed to assist conservation programs.

“…Important factors having an impact on the post-release survival of fish include fish species [62,73]; water and air temperature [74][75][76]; the depth at which fishing is carried out [77][78][79]; landing duration [80,81]; fish landing manner [52,82]; anatomical hooking locations (AHL) [83][84][85][86]; the occurrence of bleeding and tissue damage [63,76,87]; unhooking duration, and the overall time the fish is exposed to the air [82,[88][89][90][91][92][93][94]; the manner and duration of keeping fish [95][96][97]. All of the factors mentioned above are ultimately influenced by the actions and behaviours of the individual angler: the angler's experience and knowledge [87,98,99]; choice of fishing method and the type of gear used [25,100], including the type of bait [76,87,101], and primarily the type and size of the fish hook [27][28][29][30]83,[102]…”

The fish hook is a commonly known tool used in recreational fishing, which is one of the forms of active, specialised tourism. As a component of a fishing rod, the hook is intended to be anchored into the mouth of a fish and hold the fish on the end of the line while landing it. However, in the context of the protection of living aquatic resources and Catch-and-Release (C&R) fishing, its role and significance are becoming broader. In addition to the impact of the hook type on fishing efficiency, including the Catch Per Unit Effort (CPUE), the importance of hook selection in terms of minimising the resulting damage to the tissues of caught and released fish is increasing. It appears that alternative hook types, such as barbless hooks and circle hooks, are safer for fish in the aforementioned context while not significantly reducing fishing efficiency. This review study is aimed at describing the design, types, and role of the fish hook in modern C&R angling, including the impact of the hook type on both fishing efficiency and the safety and welfare of released fish, which translates into the status and protection of living aquatic resources. The issues presented in the study highlight a number of related technical, biological and social factors that are specific to inland angling in particular. Such a holistic perspective can be used to support the effective management of recreational fishing, which, as one of the most popular human activities when in contact with water, has a very significant impact on the state of the environment and, thus, on the possibility of tourism development.

Catch-and-release (C&R) is a popular management tool that can support sustainable development of recreational fisheries, if anglers adopt scientifically informed "best practices." However, although the role of best practices is widely established in the academic literature, this knowledge is not always disseminated to anglers. In this paper, we investigated if and to what extent local management organizations provided best practice information to anglers. Based on a sample of 331 Swedish organizations, we reviewed the websites through which these organizations sold fishing licenses.Our review demonstrated widespread use of C&R as a management tool yet a general lack of best practice information. Among the small fraction of organizations that mentioned best practices, most mentioned only a single practice, with little consistency among practices that received attention. In addition, best practice information was particularly lacking for pike (Esox Lucius) and perch (Perca fluviatilis), which are by far the most landed and released species nationally. We discovered major knowledge deficiencies that provide insights about where and how to focus efforts for improving best practice information, in the context of local recreational fisheries management.
