Feeding performance of juvenile hatchery-reared spotted seatrout Cynoscion nebulosus.
The feeding performance of individual hatchery-reared (HR) and wild juvenile spotted seatrout Cynoscion nebulosus was compared across a series of six 1·5 h feeding exposures over a 3 day period in a controlled experiment. The predation cycle served as a context for discerning feeding performance elements. The experimental design facilitated assessments of the effects of experience, motivation d...
متن کاملPartial characterization of a sex-steroid binding protein in the spotted seatrout (Cynoscion nebulosus).
A sex-steroid binding protein (SBP) that binds both testosterone and estradiol-17 beta was identified in the plasma and ovarian interstitial fluids of the spotted seatrout, Cynoscion nebulosus. Scatchard analysis revealed a single binding component with dissociation constants of 4.89 +/- 0.19 and 3.13 +/- 0.11 nM and binding capacities of 423 +/- 25 and 482 +/- 24 nM for testosterone and 17 bet...
متن کاملAcoustic monitoring indicates a correlation between calling and spawning in captive spotted seatrout (Cynoscion nebulosus)
BACKGROUND Fish sound production is widespread throughout many families. Territorial displays and courtship are the most common reasons for fish sound production. Yet, there is still some questions on how acoustic signaling and reproduction are correlated in many sound-producing species. In the present study, our aim was to determine if a quantitative relationship exists between calling and egg...
متن کاملHabitat Preferences of Spotted Seatrout, Cynoscion nebulosus, in Coastal Louisiana: A Step Towards Informing Spatial Management in Estuarine Ecosystems
Louisiana wetlands are disappearing at a dramatic rate, providing an impetus for identifying the relative value to fishes of a matrix of estuarine habitat types. The distribution, relative abundance, biomass, and length of spotted seatrout, Cynoscion nebulosus (Cuvier) were examined in Barataria Bay, Louisiana, in relation to habitat type and abiotic variables. Spotted seatrout were collected f...
متن کاملRegional Patterns in the Otolith Chemistry of Juvenile Spotted Seatrout (Cynoscion nebulosus) Differ under Contrasting Hydrological Regimes
The value of using otolith chemistry to characterize recruitment in terms of natal source regions depends on how consistently spatio-temporal variation can be resolved. The objective of this study was to compare regional classification patterns in the otolith chemistry of juvenile Spotted Seatrout (Cynoscion nebulosus) between two years experiencing disparate hydrological regimes, and separated...
