Growth of newly settled red drum Sciaenops ocellatus in different estuarine habitat types
We examined growth of recently settled juvenile red drum in salt marsh, seagrass, oyster reef, and on nonvegetated bottom areas in the Galveston Bay system of Texas (USA). We estimated growth using otolith microstructure from free-ranging fish collected in different habitat types and also measured growth of red drum in experimental enclosures where fish movement was restricted. Otolith growth w...
متن کاملUtilization of subtropical seagrass meadows by newly settled red drum Sciaenops ocellatus: Patterns of distribution and growth
Spatial and temporal variability in distribution and growth of newly settled red drum Sciaenops ocellatus were examined in the Aransas Estuary, Texas, USA. Overall, 1891 red drum larvae and early juveniles (4 to 30 mm standard length. SL) were identified from weekly epibenthic sled collections taken during the annual recruitment period (September-December 1994). Densities ranged from 0.0 to 3.4...
متن کاملVulnerability of newly settled red drum (Sciaenops ocellatus) to predatory ®sh: is early-life survival enhanced by seagrass meadows?
We conducted predation experiments to evaluate the vulnerability of red drum Sciaenops ocellatus (Linnaeus) larvae and early juveniles to pin®sh Lagodon rhomboides (Linnaeus) predators. Experiments were designed to analyze the eects of habitat complexity, prey size, and rearing condition on prey vulnerability. Three structurally dierent habitats [unvegetated (substrate only), shoal grass Halo...
متن کاملCondition of larval and juvenile red drum (Sciaenops ocellatus ) from estuarine nursery habitats
RNA:DNA ratios of larval and juvenile red drum (Sciaenops ocellatus) collected from nursery habitats in the Aransas Estuary, Texas, in 1994 were quantified using a highly sensitive ethidium-bromide fluorometric technique. RNA:DNA ratios of wild red drum were evaluated by comparing individual values to a linear regression model derived for starved laboratoryreared red drum. Wild red drum were in...
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...
