“…Results could also provide estimates on the proportion of Red Snapper from state waters that are harvested by out-ofstate fishers. Further, this reward-tagging approach could also be used to estimate the vulnerability of different sizes of Red Snapper to harvest, providing information on the size selectivity of the fishery (Pine et al 2003;Bacheler et al 2010). Lastly, combining tagging data with harvest surveys could be used to directly estimate catchability (Pine et al 2003).…”

Accurate estimates of exploitation rate are essential to the management of exploited fisheries. Tagging studies are often used to estimate exploitation rates, but the performance of these approaches depends strongly on study design characteristics and the magnitude of assumption violations. We simulated a suite of candidate study designs for 1‐year high‐reward and variable‐reward tagging studies, exploring a range of sample sizes (number of tagged fish), exploitation rates, tagging mortality rates, tag loss rates, proportions of double‐tagged fish, and spatial variation in fish density, tag releases, and fishing effort. We calculated the uncertainty, biases, and reward costs of these candidate study designs to determine the most cost‐effective approach to accurately estimate exploitation rate for Red Snapper Lutjanus campechanus in Alabama waters of the Gulf of Mexico. We also investigated how incorrectly assuming a 100% reporting rate would affect these study results. Our simulations demonstrated that using all high‐reward tags provided more accurate and precise exploitation rate estimates than the variable‐reward approach but only if 100% reporting could be safely assumed. Further, distributing tags uniformly over the study area when the true spatial distribution of the population and fishing pressure varied over that area drastically biased exploitation rate estimates, suggesting that prior knowledge of the population's true spatial distribution over the study area is needed to ensure accurate estimates of exploitation rate. The most cost‐effective study design involved tagging between 400 and 1,600 fish with high‐reward tags, with 40% of the fish double‐tagged, and the tags spatially distributed in the same proportion as the population. However, violation of the 100% reporting rate assumption resulted in a proportional downward bias in the estimated exploitation rate. Simulation studies such as this are critical to ensure that cost‐effective study designs produce accurate and precise estimates of exploitation rate, particularly for high‐value species such as Red Snapper.

“…We consider the collection of age-0 red drum by seines to be relatively nonselective over the range of lengths encountered in this study (11-104 mm TL). Gill nets can be highly size-selective when a single or minimum mesh size is used (Bacheler et al 2010b); however, the gill nets used in our study consisted of a wide range of mesh sizes, likely minimizing size-selectivity effects within an age class. Because sample sizes were limited for the gill net survey (e.g., length of time series was short, number of red drum caught within some years was modest), we also analyzed length data from a long-term tagging program that used multiple gears to collect red drum, and selectivity patterns of these combined gears was unknown.…”

“…The major benefits of using tagging data to calculate apparent red drum growth rates is that the time series is much longer and more age-1 red drum were collected early in the season, but the downside is that the selectivity patterns of these gears are not known and may not be equal for all sizes of fish (Bacheler et al 2010b). Apparent red drum growth rates were then compared with global age-1 or age-2 abundance using a linear regression model ( Fig.…”

Density dependence can stabilize or destabilize population size through negative or positive feedback controls operating over different spatial and temporal scales. While many species have been shown to exhibit density dependence, the topic has received little attention in estuaries where environmental variability and larval supply are often considered to be the primary drivers of population dynamics. We used multiple long-term, fishery-independent data sets and a unique modeling approach to test the hypothesis that juvenile red drum (Sciaenops ocellatus) exhibit density-dependent habitat use and growth rates in estuaries in North Carolina, USA. Age-1 red drum exhibited density-dependent habitat use after accounting for environmental and landscape variables, disproportionately increasing northward and coastward in the study area at high abundance. Apparent individual growth rates of age-0 and age-1 red drum were generally negatively related to the abundance of their own age classes, but evidence of density-dependent growth rates for age-2 red drum was weak to nonexistent. Changes in spatial distribution of red drum when overall abundance was high did not overcome density-dependent effects on individual growth rates. Thus, density-dependent effects have potential negative feedbacks on population growth in estuaries and should not be ignored in future theoretical or empirical estuarine studies.Résumé : La dépendance de la densité peut stabiliser ou déstabiliser la taille d'une population par l'entremise de rétroac-tions négatives ou positives oeuvrant à différentes échelles spatiales et temporelles. S'il a été démontré que de nombreuses espèces présentent une dépendance de la densité, le sujet a reçu peu d'attention en ce qui concerne les estuaires, où la variabilité environnementale et l'abondance des larves sont souvent considérées comme les principaux moteurs de la dynamique des populations. Nous avons utilisé de multiples ensembles de données à long terme indépendants de la pêcherie et une nouvelle approche de modélisation pour tester l'hypothèse selon laquelle l'utilisation de l'habitat et les taux de croissance des tambours ocellés (Sciaenops ocellatus) juvéniles dans les estuaires de la Caroline du Nord (États-Unis) sont dépendants de la densité. À forte abondance, l'utilisation de l'habitat des tambours ocellés d'un an était dépendante de la densité si les variables environnementales et du paysage étaient prises en compte, cette dépendance augmentant disproportionnellement vers le nord et les côtes dans la zone d'étude. Les taux de croissance individuels apparents pour les tambours ocellés de zéro et un an présentaient généralement une relation négative avec l'abondance de la classe d'âge concernée, mais les données reflétant des taux de croissance dépendants de la densité pour les tambours ocellés de deux ans étaient rares à non existantes. Des modifications de la répartition géographique des tambours ocellés durant les périodes de grande abondance générale ne compensaient pas les effets dépendants de la d...

“…Fish can be segregated perfectly or imperfectly by size and age for some species, and fleets choose particular fishing areas to target one specific size or age (Walters and Martell 2004;Bacheler et al 2010). See also Skonhoft and Gong (2014) for perfect selectivity assumption for the old cohort in age-structured modelling of the Atlantic salmon fishery.…”
