Understanding the mechanisms controlling recruitment in fishes is a major problem fisheries science. Although literature on large and growing rapidly, it primarily species specific. There no conceptual framework to integrate existing information larval fish ecology its relationship survival recruitment. In this paper, we propose an integrating based body size. all are small relative adult fish, total length at hatching differs among by order of magnitude. As many factors critical growth size...
Published life-history parameters for sharks, skates, and rays over a wide geographic range were used to develop predictive models estimate that are difficult measure or have not been previously estimated in elasmobranch species. We determined empirical relationships between body size (total length) length at maturity (L m ) age (T ). The data determining these relationships, the von Bertalanffy asymptotic [Formula: see text] growth rate (k), natural mortality (M) maximum max describe...
Recent theoretical work suggests that small‐scale turbulence enhances encounter rates between larval fish and their prey. This finding has been extended to suggest feeding will increase in turbulent environments. However, this extrapolation assumes no detrimental effects on post‐encounter behaviors (e.g. pursuit success). We develop an analytical model estimate the probability environments successfully pursue encountered show overall of is a dome‐shaped function velocity height location...
Angle-resolved photoemission from atomically uniform silver films on iron (100) shows quantum-well states for absolutely determined film thicknesses ranging 1 to ∼100 monolayers. These can be understood in terms of Fabry-Pérot modes an electron interferometer. A quantitative line shape analysis over the entire two orders magnitude thickness range yields accurate measurement band structure, quasiparticle lifetime, reflectivity, and phase shift. Effects confinement energy gap, reflection...
We used an individual-based Monte Carlo simulation model to explore how changes in the mean and variance of growth rates individuals a larval fish cohort interact with size-dependent predation affect number characteristics individual survivors. Small initial rate can change survival over first 60 d life 10-to 30-fold. But when among is high, be substantially higher than expected from rate. Selection for faster-growing becomes stronger increasing In some cases, > 80% survivors may come...

We used life history traits to categorize vulnerability of elasmobranchs exploitation.However, the utility this approach required that links between histories and population dynamics be explored.We constructed standardized three-stage matrix models for 55 species sharks rays.Using these we (1) conducted elasticity analyses determine how vital rates mortality (M) fertility (f) influence elasmobranch growth rate r, (2) determined response changes in levels exploitation, (3) estimated...
The ratio of tissue RNA to DNA (R/D) is a widely used index recent growth and nutritional condition in larval juvenile fish. To date, however, no standard technique for measuring nucleic acids has been adopted. Because methodological details can affect the estimate R/D, researchers using different analytical protocols have unable compare ratios directly. Here, we report on results an international interlaboratory calibration 4 spectrofluorometric quantify acids. Replicate sets 5 samples 2...
Abstract Accumulating evidence indicates that as global temperatures rise, reproductive behaviors, including migrations, are occurring earlier across a range of taxa. Alone, these changes ecologically important; however, for some fish populations, management practices may unknowingly interact with climate‐induced in phenology, leading to unanticipated fishing mortality. The potential such an interaction exists the Chesapeake Bay Striped Bass Morone saxatilis fishery, which opens on same week...
Abstract During the past century, field of fisheries oceanography has dominated study population connectivity in marine environments. The influence physical and biological processes their relationship to transport retention early life history stages been central providing insight into structuring connectivity. However, focus on dispersive meant that role adults received less attention is not fully understood or appreciated. We argue play a vital for wide range taxa hypothesize adult‐mediated...

Changes that occurred in the distribution of adult Lake Michigan yellow perch (Perca flavescens) phenotypic traits suggest maternal effects on larval may be substantially influencing recruitment this heavily exploited species. We investigated larvae at hatching 10 lines to test null hypothesis no effect phenotype offspring and condition.

The development of foraging abilities is crucial to the survival and subsequent recruitment young fishes. We examined experimentally notion that species are so different useful generalizations across taxa impossible. investigated ontogeny feeding, reflected in their functional responses, three Great Lakes' fishes, alewife (Alosa pseudoharengus), yellow perch (Perca flavescens), bloater (Coregonus hoyi). No strong evidence species-specific differences feeding ability was found. A single...
Abstract Analyses of the population dynamics blue crab Callinectes sapidus have been complicated by a lack estimates instantaneous natural mortality rate ( M ). We developed first direct for this species solving Baranov's catch equation given annual survival and exploitation rate. Annual rates were estimated from tagging study on adult female crabs in Chesapeake Bay, female‐specific same stock comparing commercial catches with abundances dredge survey. also used eight published methods based...
Abstract For federally managed fisheries in the USA, National Standard 1 requires that an acceptable biological catch be set for all and this avoid overfishing. Achieving goal data‐poor stocks, which stock assessments are not possible, is particularly challenging. A number of harvest control rules have very recently been developed to sustainable catches fisheries, but ability most these overfishing has tested. We conducted a management strategy evaluation assess several proposed situations....
Abstract Atlantic menhaden, Brevoortia tyrannus, is an abundant, schooling pelagic fish that widely distributed in the coastal Northwest Atlantic. It supports largest single-species fishery by volume on east coast of United States. However, relatively little known about factors control recruitment, and its stock–recruitment relationship poorly defined. menhaden managed as a single unit stock, but fisheries environmental variables likely act regionally recruitments. To better understand...
Abstract Implementation of an ecosystem approach to fisheries management (EAFM) for forage fish requires methods evaluate tradeoffs associated with competing objectives that focus on supporting fishery yields or providing food predators.

The (with 61 trophic groups and 8 fishing fleets) was parameterized fitted time series using data from stock...
Atlantic menhaden ( Brevoortia tyrannus ) support the largest fishery by volume on United States East Coast, while also playing an important role as a forage species. Managers’ and stakeholders’ increasing concerns about impact of harvest ecosystem processes led to evolution in assessment management this species from purely single-species approach approach. The first coastwide stock for used virtual population analysis (VPA). Subsequent assessments forward projecting statistical catch-at-age...

Crustaceans display discrete and biphasic growth as a result of the molting process, so traditionally used von Bertalanffy model does not capture well phenomena associated with molting-based growth. A molt-process can predict crustacean growth, including temperature dependence intermolt period that produce extended overwintering during which ceases. This study parameterized for blue crab (Callinectes sapidus; Portunidae). Crab histories were observed individual crabs held in field enclosures...
