“…In this study, over 95 % of all red drum collected in 1994 were from September and October spawns. Our results on spawning seasonality are consistent with findings reported in the north-central Gulf of Mexico (Comyns et al 1991) and in Florida, USA (Peters & McMichael 1987). The hatch-date distribution also indicated that spawning intensity was relatively continuous through-out the primary spawning period (September-October).…”

“…Growth rates were similar to estimates reported by Peters & McMichael (1987) for red drum in Tampa Bay, Florida. The size-at-age equation estimated that the mean length of 20 and 40 d individuals from Tampa Bay was 9.0 and 20.5 mm SL, respectively.…”

“…Spawning occurs in early fall (September-November; Comyns et al 1991) in offshore waters and areas near tidal inlets that connect the Gulf of Mexico to inshore estuarine habitats (Holt et al 1983, Peters & McMichael 1987. Tidal currents move larvae through passes, and red drum settle into demersal sea-'50 ' grass habitats at approximately 6 to 8 mm standard length (Holt et al 1983, Peters & McMichael 1987. Although utilization of estuarine seagrass meadows by newly settled red drum is fairly well documented, our understanding of growth variation during this interval is extremely limited.…”

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 ind. m-2, with peak values observed in mid to late October. Density varied significantly between habitats (Halodule wrjghtii vs Thalassia testudinum) and among sites. Otolith-based techniques were used to determine hatch-date distributions and individual growth rates of newly settled red drum. Hatch dates of individually aged red drum (n = 324) ranged from September 4 to October 30 (57 d ) . Hatch dates \yere used to separate individuals into 10-d cohorts and cohort-specific growth rates were estimated from exponential size-dt-age plots. Cohort-specif~c Instantaneous growth coeffic~ents ( g ) ranged from 0.041 to 0.058 d-' with highest values occurring for m~d-season cohorts. Spatial and temporal patterns of recent growth (mean increment width over 5 d) were also investigated. Recent growth rates were highest for mid-season cohorts and relatively uniform between habitats and among sites. Since spatial trends in density were not explained by growth differences, we hypothesize that factors other than growth potential were influencing the distribution of newly settled red drum in the Aransas Estuary.

“…The fecundity of red drum depends on fish size, and a female red drum can lay eggs ranging from 200,000 to more than three million per batch. Red drum eggs tend to be subject to high mortality (Peters and McMichael 1987;Goodyear 1989). Larval red drum use vertical migrations to ride high salinity tidal currents into tidal creeks and shallow salt marsh nursery habitats (Wenner 1999).…”

“…Holt et al (1981) observed active predation by red drum larvae when the yolk sac was exhausted and the mouth and eyes were developed (3 d old); Lee et al (1984) also reported the onset of active feeding at Day 3 to 4 when post-yolk-sac larvae were about 2.7 mm long. Peters & McMichael (1987) collected 800 red drum larvae in Tampa Bay, Florida, USA, from 1981 to 1983. Their collections were completed at night, and they found that fully 85 % of larval stomachs were nocturnally empty.…”

Phototactic behavior of red drum Sciaenops ocellatus larvae (age = 1 to 17 d posthatch, size = 2.5 to 7.5 mm standard length) was examined. Numerical percent of test larvae phototactically responding per sample was determined after dark and light adaptation upon exposure to different stimulus light intensities and compared with dark or light controls. The relative spectral composition In these experiments was similar to that measured at mid-afternoon at 1 m depth in a coastal channel where red drum larvae naturally occur. Day 1 larvae were not photoresponsive; all tested older larvae showed positive phototaxis at higher stimulus intensities [> ca 10-4 (Day 16) to 10-' (Day 3) pE m-2 S-'] and negative phototaxis at lower light levels [as low as ca 10-S (Day 3) to 10-' (Day 5) pE m-' S-']. The light range for positive phototaxis generally increased with larval age, as did the percent positive response when tested at the same light levels. These results indicate an ontogenetic increase in photoresponsiveness, beginning as early as Day 3 posthatch. Light-adapted larvae as young as Day 4 exhibited a lower response than dark-adapted larvae at the same stimulus intensities, indicating dark and light adaptation. Estimated intensity thresholds for negative phototaxis were compared with nearbottom daylight intensities in 2 coastal channels where red drum larvae occur. Results indicate there is sufficient daylight available throughout the water column in the field for photoperception by red drum larvae. Using an estimate from the literature of a 3 to 4 log unit higher threshold for feeding than for negative phototaxis, we conclude that natural intensities at depth are adequate for visual predation during daylight hours.
