“…There has been research indicating that higher RAMP scores in a variety of fish species are correlated with fishing stressor duration, higher post-release predation and mortality (Brownscombe et al, 2015;McArley and Herbert, 2014). However, in our study, we observed no apparent statistical difference of RAMP scores between treatment groups (Tab.…”

-There is growing interest in educating anglers on catch-and-release (C&R) best practices, yet there is little information on whether angler education programs yield measurable improvements in fish condition and survival. As such, we conducted a study focused on mixed-gender youth groups (aged 8-10) and contrasted three levels of training intervention. Treatment 1 training had no mention of C&R best practices. Treatments 2 and 3 trainings involved visual aids to illustrate best practices, while Treatment 3 added a hands-on demonstration. When caught by the most highly trained participants, fish experienced the least amount of air exposure, but were handled for longer periods, as trained anglers were more careful. Higher levels of training led to a higher likelihood that anglers wet their hands and used a bucket filled with water while handling fish but all treatment groups yielded similar incidences of deep hooking and bleeding. Overall, mortality (initial and after ∼12 h) was low across all treatments. Our findings suggest that a short (∼20 min) fishing workshop can transfer information on C&R practices, at least in the short-term, that can lead to some improved conditions for angler-caught fish. It is unclear the extent to which this information is retained in the long-term or how different target populations or training strategies might influence knowledge transfer and adoption and thus biological outcomes. With growing interest in sharing C&R best practices with anglers, we suggest that there is need for additional research on outreach strategies to ensure that such efforts are effective and yield meaningful benefits to fish welfare and conservation.Keywords: angler education program / catch-and-release practices / environmental education and outreach / recreational fisheries / fish injury and stress / knowledge transfer Résumé -Les programmes d'éducation à la pêche transmettent-ils les bonnes pratiques du «capture-relâcher» aux jeunes pêcheurs, conduisant à une amélioration mesurable dans la condition et la survie des poissons ? Il y a un intérêt croissant dans l'éducation des pêcheurs pour les meilleures pratiques de la capture et du relâcher (C & R), mais il y a peu de connaissance pour savoir si les programmes d'éducation des pêcheurs donnent des améliorations mesurables dans la condition du poisson et de sa survie. Ainsi, nous avons mené une étude sur des groupes de jeunes garçons et filles (âgés de 8 à 10) et comparé trois niveaux d'intervention de formation. Le groupe 1 n'avait aucune information sur les meilleures pratiques C & R. Les groupes 2 et 3 avaient une formation utilisant des aides visuelles pour illustrer les meilleures pratiques, et le traitement 3 avait en plus une démonstration pratique. Quand il est pris par les participants les plus formés, le poisson a subi le moins d'exposition à l'air, mais a été manipulé pendant de longues périodes, parce que les pêcheurs formés étaient plus prudents. Les niveaux les plus élevés de formation ont conduit à une plus forte probabilité que les...

“…Similar to previous studies, Brownscombe et al (2015) found that fight time, air exposure, and handling time were important factors influencing the likelihood of bonefish survival after release. However, they also found that physiological stress was greater in association with warmer water temperatures found at the lower latitude of their study site in Puerto Rico, which may have implications for other Caribbean fisheries.…”

The fish of the sub-tropical and tropical flats including bonefish (Albula spp.), Atlantic tarpon (Megalops atlanticus), and permit (Trachinotus falcatus), capture the imagination of specialized coastal marine recreational anglers. Until recently, little was known about the biology and natural history of these iconic species. Flats ecosystems are under threat from coastal development and environmental change while basic information on demographics and population size is lacking. This makes it difficult to understand the consequences of these threats, or to formulate potential management strategies. Through extensive partnerships involving anglers, industry, conservation organizations, natural resource agencies, and academics, the mysteries surrounding these species are starting to be solved. Nonetheless, many challenges remain. The systematics of these fish is complex, particularly for the bonefish which include a number of cryptic species. Identifying the timing and habitats associated with reproduction remain high priority such that management efforts can target protecting that important life-history event. Information on the spatial ecology of flats fish at various spatial scales is being elucidated by electronic tagging studies and angler tagging programs. Habitat science for these fish continues to improve but there is still need to identify effective habitat restoration strategies. Catch-and-release science has improved dramatically (especially for A. vulpes in The Bahamas) although there is need to for additional work across regions and species. Targeted species-specific management strategies (e.g., catch-and-release regulations) as well as more ecosystem-level strategies (e.g., habitat protection and fishing effort management) are increasingly being used for active management of flats fish and their habitats. Partnerships will remain key to addressing outstanding research questions and in working cooperatively to ensure that evidence (both scientific and stakeholder knowledge) forms the basis for management decisions. ContextCoastal marine waters in tropical and sub-tropical regions are often characterized by expansive shallow areas with adjacent tidal creeks collectively referred to as Bflats^. The flats are a complex habitat mosaic comprised of mangroves, sea grass, benthic algae, sand, coral rubble, limestone, and mud bottom that supports an inherently diverse community that includes resident species and species that use these habitats as nurseries (Barbier Environ Biol Fish (2015) 98:2123-2131

Abstract-The delayed mortality rate of crab discarded during fishing operations can be under-or overestimated in laboratory holding experiments, given the unnatural conditions and the short-term duration of these experiments. To evaluate the extent to which a method affects accuracy in these estimations, we compared mortality rates established through laboratory holding with mortality inferred from a yearand-a-half long tag-return study of Dungeness crab (Cancer magister) discarded in Oregon crab fisheries. The reflex action mortality predictor (RAMP) approach, which relates reflex impairment to probability of mortality, was applied in both studies. Similar patterns in mortalityand tag return-rates with respect to fishery, sex, reflex impairment, shell hardness, and injury from the 2 studies lends support to the reliability of the laboratory-generated mortality rates. However, results suggest that mortality rates determined in captivity are likely underestimated when crab are dropped a distance of greater than 6 m (and potentially less) back to water. This underscores the importance of determining the contribution to mortality of variables in the capture, handling, and discard process that are not incorporated in a study to estimate mortality of discarded animals. Both studies also highlighted the significance of sample size when applying the RAMP approach to a fishery with low rates of discard mortality.
