Aspects of the Biology of the Red Drum, Sciaenops ocellatus, in Mississippi
Several hundred specimens of the red drum from Mississippi were critically assessed. Regression equations for standard-length (SL) versus total-length differed between males and females and between small and large members of the same sex. A single regression line represented the weight-SL relationship for males with females. For condition coefficients to be helpful, fish had to be grouped at le...
متن کاملFood of the Red Drum, Sciaenops ocellata, from Mississippi Sound
Examined digestive tracts of the red drum in Mississippi Sound contained mostly decapod crustaceans. Crustaceans accounted for 34 of 59 encountered taxa, more than reported from any other region. Nevertheless, the general diet for 104 fish with food contents out of the 107 examined is similar to that reported for red drum in several other studies from other areas. In addition to crustaceans, fi...
متن کاملA genetic linkage map of red drum, Sciaenops ocellatus.
Second-generation, sex-specific genetic linkage maps were generated for the economically important estuarine-dependent marine fish Sciaenops ocellatus (red drum). The maps were based on F(1) progeny from each of two single-pair mating families. A total of 237 nuclear-encoded microsatellite markers were mapped to 25 linkage groups. The female map contained 226 markers, with a total length of 127...
متن کاملEffects of somatolactin on melanosome aggregation in the melanophores of red drum (Sciaenops ocellatus) scales.
The effects of purified red drum somatolactin on pigment movement in red drum scales were studied in vitro and in vivo. The integument became pale within 2 min following an intramuscular injection of somatolactin (1 nmol/g body weight) in fish held in a black-background aquarium, and gradually regained its black coloration during the subsequent 30 min. No melanosome aggregation was observed in ...
متن کاملProximate composition of muscle of cage-raised red drum, Sciaenops ocellatus (Pisces: Sciaenidae), in Panama.
Resumen: La composición química del músculo de la corvina roja, Sciaenops ocellatus. cultivado en jaulas flotantes es comparable a la obtenida en cultivos de estanques de tierra o en el medio marino. La edad o el peso no fueron un factor detenninante de la composición química del músculo. Un alimento flotante del 36 % de proteína es adecuado para mantener un relativo buen crecimiento COlporal, ...
