In southern U.S. reservoirs, summer conditions may result in a reduction of suitable habitat for adult striped bass and therefore influence population dynamics and distribution. We tracked 51 adult striped bass that had been implanted with individually coded sonic transmitters for 2 years in Lake Gaston, Virginia−North Carolina, to determine the impact of habitat availability on seasonal trends in movement and distribution. Monthly movement rates of individual fish averaged 7,340 m (SE = 544 m) over the course of the study, and no significant differences in movement rates were detected among seasons or between sexes. Striped bass were relocated throughout the reservoir in all seasons despite evidence of spatial variability in the availability of suitable habitat during the summ...}, number={1}, journal={NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT}, author={Jackson, JR and Hightower, JE}, year={2001}, month={Feb}, pages={34–45} }

We developed a new telemetry approach for estimating natural and fishing mortality rates and applied it to the population of striped bass Morone saxatilis in Lake Gaston, North Carolina and Virginia. Our analyses were based on a sample size of 51 telemetered striped bass that were known to be alive and in Lake Gaston at least 1 month after capture and surgery. Relocations of live fish and fish that died of natural causes were used to estimate natural and fishing mortality rates and the probability of relocating telemetered fish. Fishing mortality rates varied seasonally, but few natural deaths were observed, so the best model incorporated a constant annual instantaneous natural mortality rate (M; ±SE) of 0.14 ± 0.02. With the uncertainty in model selection acc...}, number={4}, journal={TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY}, author={Hightower, JE and Jackson, JR and Pollock, KH}, year={2001}, month={Jul}, pages={557–567} }

Shoreline electrofishing was used to assess juvenile largemouth bass cohort dynamics from school dispersal through the yearling stage in Jordan Lake, North Carolina, 1987–1995. Measures of environmental conditions and dynamics of juvenile shad Dorosoma spp. were collected concurrently to assess their potential effects on cohort dynamics of juvenile largemouth bass. Abundance of age-0 largemouth bass at the time cohort mean lengths reached 50 mm varied significantly among years, as did growth rates and mortality from July through October. No environmental or shad effects on largemouth bass growth or mortality were detected. Overwinter mortality rates did not vary among years, despite a 50-mm difference among years in largemouth bass mean lengths going into late fall, and little evidence was found to indicate significant size-selective ov...}, number={3}, journal={TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY}, author={Jackson, JR and Noble, RL}, year={2000}, month={May}, pages={716–726} }

Shoreline electrofishing was used from 1988 to 1998 to assess the magnitude of variations in year-class strength of largemouth bass at the time cohort mean lengths reached 50 mm in Jordan Lake, North Carolina. Concurrent measures of adult stock characteristics, dynamics of larval and juvenile shad Dorosoma spp., lake elevation dynamics, and seasonal air temperatures were used to test published findings concerning factors that influence largemouth bass year-class strength. Catch rates of juvenile largemouth bass varied fourfold from 1988 to 1995. No significant relationships were observed between largemouth bass year-class size and spawning stock size, shad dynamics, or variations in lake elevations. However, late-winter and early spring air temperatures explained a significant amount of the observed variation in catch rates of age-0 largemouth bass.
