The Effects of Ageing Error on Stock Assessment for Weakfish Cynoscion regalis
Inherent uncertainties in the stock assessment for weakfish have precluded accurate and consistent advice concerning the management of commercial and recreational fisheries. Error within ageing techniques, used to assess relative age frequencies within commercial and recreational harvest, has been …

Spatial and temporal heterogeneity in life history and productivity trends of Atlantic Weakfish (Cynoscion regalis) and implications to fisheries management
… stock assessment models using Atlantic Weakfish (Cynoscion regalis) as a case study. First, spatial and temporal variation was incorporated into length-, weight-, and maturity-at-age estimates using mixed-effects models (Chapter Two). The resulting heterogeneous weight and maturity parameters then …

Exploring spatial heterogeneity of CPUE year trend and nonstationarity in fisheries stock assessment, an example based on Atlantic Weakfish (Cynoscion regalis)
… and management strategies. Atlantic Weakfish (Cynoscion regalis), one important commercial and recreational fish species along the west coast of Atlantic Ocean that was found to be declining in recent years, was selected as an example species. My study aimed to explore the possible spatial …

The use of Pulsed Energy (Flashbast) technology in the shelf life extension of selected marine and freshwater fish species stored in ice
… studied. Unskinned fillets from fresh sea trout (Cynoscion regalis) and hybrid striped bass (Morone chrysops x ~ saxatilis) were treated with 7.45 Joules/cm² of PET, stored individually in sterile polyethylene bags, and kept in ice for 21 days at 3°C. Sensory data showed no significant differences …

Measurement of Thermal Properties of Seafood
… (<i>Tilapia aurea</i>), grey sea trout(</i>Cynoscion regalis</i>), and yellow fin tuna (<i>Thunnus albacares</i>) (Wheaton, et al. 1985). Thermal properties measured were thermal conductivity, thermal diffusivity, and specific heat from 5 to 30<sup>o</sup>C. Enthalpy was measured from -40 to …

Investigating the performance of process-observation-error-estimator and robust estimators in surplus production model: a simulation study
… two example fisheries: the Atlantic weakfish (Cynoscion regalis) and the black sea bass (Centropristis striata) southern stock. Our results indicated that POE_N is the estimator with best performance among all six estimators with regard to both accuracy and precision for most of the cases. …

Evaluation of Fish Scale Chemistry for Determining Habitat Associations
… levels in scales from juvenile weakfish (<em>Cynoscion regalis</em>) from five estuaries along the Atlantic coast were measured. Significant variability in multivariate elemental signatures was found among estuaries and between collections from 1996 and 1997. Linear discriminant function …
