Concentrations of 11 PFASs were determined in muscle and whole fish for six species collected from Charleston, South Carolina (SC) the assessment potential health risks to humans wildlife. Across all capture locations, total PFAS levels significantly higher than fillets by a factor two- three-fold. Mean ∑PFAS concentrations varied 12.7 33.0 ng/g wet weight (ww) 6.2–12.7 ww fillets. For individual fish, ∑PFASs ranged striped mullet 85.4 spotted seatrout, values 6.2 27.9 spot. The most...

Evolutionary responses to the long-term exploitation of individuals from a population may include reduced growth rate, age at maturation, body size and productivity. Theoretical models suggest that these genetic changes be slow or impossible reverse but rigorous empirical evidence is lacking. Here, we provide first demonstration genetically based reversal fishing-induced evolution. We subjected six populations silverside fish (Menidia menidia) three forms size-selective fishing for five...

'Good genes' models of sexual selection suggest that elaborate male ornaments have evolved as reliable signals quality because only males high genetic viability are able to develop and maintain them. Females benefit from choosing such individuals if is heritable. A key prediction the offspring with mating displays will perform better than those less males, but it has proved difficult demonstrate an effect independently effects differences in parental investment. We tested for 'good linked...

The potential of fishing mortality to cause rapid evolutionary changes in life history has received relatively little attention. By focusing only on ecological responses, standard fisheries theory and practice implicitly assume either that genetic influences the wild are negligible or natural selection adaptation is a slow process can be effectively ignored. Lack contrary evidence allowed these assumptions persist. Drawing upon >25 years research Atlantic silverside (Menidia menidia), we...

Fish consumption is an important route of exposure to persistent organic pollutants (POPs) in dolphins as well humans. In order assess the potential risks associated with these contaminants, 39 whole fish and 37 fillets from representing species consumed by humans captured Charleston Harbor tributaries, South Carolina, USA, were measured for a suite POPs. Polychlorinated biphenyls (PCBs) predominant contaminant concentrations ranging 5.02 232.20 ng/g 5.42-131.95 (weight weight ww) followed...

Parasites impose an energetic cost upon their hosts, yet, paradoxically, instances have been reported in which infection is associated with enhanced, rather than diminished, host growth rates. Field studies of these parasite effects are problematic, since the pre–infection condition hosts generally unknown. Here, we describe a laboratory experiment rate and body 76 laboratory–reared three–spined stickleback fishes were examined before, during after each fish was fed infective stage parasitic...

Abstract Although laboratory mate choice experiments and field studies often reveal certain traits of male three-spined sticklebacks (as well as other model species) to be attractive searching females, evidence that mating with males possessing such improves offspring survival performance is scarce. In particular, there a lack unambiguous data linking preferred inherited genetic 'viability', which are essential for 'good genes' models sexual selection. this paper, we provide protocol...

ABSTRACT Tail-flip escape swimming by the brown shrimp Crangon crangon has been investigated across a range of body lengths (11–69 mm) using high-speed video analysis. This revealed several novel aspects tail-flip mechanism when compared with that other decapod crustaceans have studied. (i) The pattern flexion in C. produces movement cephalothorax as well abdomen about centre mass. (ii) Shrimps form ‘head-fan’ their antennal scales, addition to tail-fan formed uropods, apparently for...

ABSTRACT Tail-flip escape trajectories of the brown shrimp Crangon crangon have been investigated in response to a natural predator, cod Gadus morhua, and an artificial stimulus. Shrimps escaped by rolling their left or right during initial tail-flip response, thereafter swam on side. As result laterally directed first tail-flip, angles always lay between 75° 156° with respect (pre-escape) longitudinal axis (anterior=0°) shrimp. Symmetrical attacks from either head-on tail-on produced...

The extent, corrected for body size, and intensity of nuptial coloration breeding male three‐spined sticklebacks Gasterosteus aculeatus L. from a Scottish freshwater population were highly variable but correlated, both in the field after period nest‐building laboratory. However, marked changes occurred between laboratory screenings coefficients variation amongst males decreased. In general, increased screenings, size‐corrected extent not consistently directional. For indices, there was...

The majority of recent studies investigating the habitat value intertidal oyster reefs have compared nektonic assemblages on natural reefs, salt marshes, mud bottom, and subtidal shell habitats using methods that involve some degree disturbance. current study used a novel, non-destructive sampling approach involving deployment drop net around plots to compare associated with (natural enhanced) those neighboring soft sediment at 3 sites in South Carolina. At each site, organisms collected...

Abstract Spotted Seatrout Cynoscion nebulosus are vulnerable to mortality in winter when water temperature decreases rapidly. Temporary fishery closures response population declines should be based on a thorough understanding of the magnitude mortality. We used three methods estimate low‐temperature tolerance Seatrout: chronic lethal method (CLM) and acclimated exposure (ACE) using both static fluctuating temperatures. All use an environmentally realistic change 1°C/d. Fish 14°C ( n = 24)...

A year-round survey of American eels Anguilla rostrata was performed at 5 localities in South Carolina (SC), USA, 15 yr after the first infection by nematode Anguillicoloides crassus reported from Winyah Bay, SC. Infections adult stages A. swimbladder lumen occurred with a prevalence 45% (n = 479), mean intensity (± SE) 2.3 ± 0.2 worms per infected eel (range 1-22), and abundance 2.0 0.1 among all eels. larval wall prevalence, intensity, 29%, 2.4 0.3 1-15), 0.7 0.1, respectively 471)....

Kudoa inornata is a myxosporean parasite that develops in the somatic muscle of spotted seatrout Cynoscion nebulosus, an economically and ecologically important fish estuaries harbors southeastern North America. In South Carolina (SC), USA, over 90% wild adult are infected. To inform potential mitigation strategies, we conducted 3 experiments using naïve sentinel infectious stages K. naturally present raw water from Charleston Harbor, SC, to determine (1) if infection follows seasonal...

Abstract Little is known about the infection status of glass eel and elver stages American Anguilla rostrata by invasive swimbladder parasite Anguillicoloides crassus. This study examined adult larval A. crassus in eels (n = 274) elvers 199) collected during March–December 2013 from an ladder at a dammed creek near Charleston, SC, USA.

There is strong evidence that genetic capacity for growth evolves toward an optimum rather than absolute maximum. This implies fast has a cost and trade-offs occur between other life-history traits, but the fundamental mechanisms are poorly understood. Previous work on Atlantic silverside fish Menidia menidia demonstrated trade-off swimming performance. We hypothesize derives from competing metabolic demands associated with activity. tested this by measuring standard rate (MSTD), maximum...
