We also evaluated the properties of two metabolic indices, marginal metabolic scope (MMS) and limiting oxygen concentration (LOC), as indicators of metabolic scope. We found that oxygen limitation has its greatest impact near the optimum temperature for growth of the species. At 29 °C a reduction from 6.00 mg/L to 4.00 mg/L caused a 50% reduction in growth rate while at 27 °C the reduction had no significant effect on growth rate. The results are particularly relevant because these temperatures and oxygen concentrations are commonly observed in nursery areas during summer months. At all temperatures fish from the lowest oxygen treatment (1.75 mg/L) had negative growth rates. Comparisons between daily oscillating oxygen treatments and constant treatments failed to demonstrate significant effects. At temperatures past the optimum, growth rates between the 6.00 mg/L and 4.00 mg/L treatments were not statistically different. LOC was significantly affected by temperature, oxygen, and their interaction. Estimates were positively correlated with oxygen treatment (R2 > 0.71) and negatively correlated with temperature at moderate and low oxygen concentrations (R2 > − 0.84). MMS was significantly affected by temperature and oxygen and was significantly correlated with oxygen treatment (R2 > − 0.91), but correlations with temperature were not as clear. In conclusion, oxygen and temperature interactions have significant effects on metabolic scope and growth rates of fish, well above the accepted hypoxia threshold of 2.00 mg/L and MMS has proved a useful estimator of the metabolic scope of the organism within an environment.}, number={2}, journal={JOURNAL OF EXPERIMENTAL MARINE BIOLOGY AND ECOLOGY}, author={Del Toro-Silva, F.

Unfortunately, proactive studies addressing the potential of stock enhancement to accomplish management goals prior to the implementation of enhancement efforts are uncommon. We outline an ecologically based, pilot protocol with which to address the potential of fisheries stock enhancement using hatchery-reared (HR) organisms, through trial releases coupled with laboratory and field experiments with juvenile summer flounder Paralichthys dentatus. Released HR fish did not persist in nursery habitats in which wild fish enjoyed relatively long residence times and high sur- vival. Multiple lines of observations and evidence suggest that the relatively rapid disappearance of released HR fish was not a result of emigration. Caging and tethering trials, coupled with previously obtained behavioral data, suggest that the poor performance of HR fish in this study was a result of increased susceptibility to predation-induced mortality, as compared with wild fish. These results suggest that post-release survival of HR summer flounder might be increased by (1) improving meth- ods of predator-conditioning, (2) releasing HR fish in sites that serve as natural refuges from preda- tors, or (3) releasing fish at larger sizes. While poor post-release survival of HR summer flounder may limit the success of stock enhancement efforts with this species, we suggest that conclusions regard- ing the potential of stock enhancement as a management tool can only be made if biological in- formation is coupled with economic information to predict economic costs associated with stock enhancement relative to costs associated with alternative management approaches.}, number={2003}, journal={MARINE ECOLOGY PROGRESS SERIES}, author={Kellison, GT and Eggleston, DB and Taylor, JC and Burke, JS and Osborne, JA}, year={2003}, pages={263–278} }

Many of these systems are strongly influenced by variable wind stress and freshwater inputs that can increase heterogeneity in estuarine habitat for fishes. We use mobile sonar surveys within the Neuse River Estuary System, NC, USA to assess the distribution and behavioral patterns of juvenile anchovies, Anchoa spp. 25-65 mm TL, over a broad range of spatial scales in relation to diel and seasonal changes in water quality including stratification, hypoxic events and copepod distribution. Results from our study indicate that episodic stratification-induced hypoxic events can reduce suitable habitat volume for anchovies by more than 50%. Furthermore, our sampling suggests that hypoxia causes spatial separation between plankton and the grazing fishes. Under stratified oxygen conditions, we observe higher densities of copepods in hypoxic bottom water. Finally, we report that reductions in available habitat caused an increase in local densities of fishes and may result in increased competition for resources. These spatially explicit data are critical for developing trophic dynamic models that predict the response of fish communities to natural and anthropogenic impacts on the system.}, number={3}, journal={AQUATIC LIVING RESOURCES}, author={Taylor, JC and Rand, PS}, year={2003}, month={Jul}, pages={191–196} }

In shallow, throughout estuarine systems, low DO can occur in two broad categories: a diel oscillating pattern resulting in repeated nocturnal hypoxia due to the photosynthesis-respiration cycle of algal populations, or as prolonged bottom water hypoxia or anoxia caused by stratification. A series of laboratory experiments was conducted to characterize the physiological performance of juvenile southern flounder, Paralichthys lethostigma, (55-65 mm TL) exposed to four treatments of DO: (1) constant normoxia (6.50+/-0.50 mg O(2) l(-1)), (2) constant hypoxia (2.79+/-0.19 mg O(2) l(-1)), (3) constant intermediate hypoxia (4.74+/-0.18 mg O(2) l(-1)), and (4) an oscillating oxygen environment cycling dielly between the normoxic and hypoxic levels (2.8-6.2 mg O(2) l(-1), daily mean=4.40 mg O(2) l(-1)). Routine respiration was positively correlated with DO level and increased significantly during the day in the oscillating treatment in response to increasing DO. Ventilation rates were negatively correlated with the DO level in the constant treatments and increased significantly at night in the oscillating treatment in response to nocturnal hypoxia. Similarly, hematocrit levels were negatively related to DO levels in the constant treatments after 5 and 26 days of exposure to the treatments. Hematocrit levels also increased significantly the oscillating treatment, apparently in response to the episodic nocturnal hypoxia. Growth was significantly reduced in the 2.8 mg O(2) l(-1) treatment and the oscillating treatment but not in the 4.7 mg O(2) l(-1) treatment. Acclimation was evident by an increase in growth rates from week 2 to week 3 and a decrease in hematocrit levels between 5 and 26 days of exposure in the 2.7 and 4.5 mg O(2) l(-1) treatments but was not evident in the normoxic or oscillating treatments. These results suggest that a juvenile fish must remain in even moderately low DO in order for acclimation to occur. The research presented demonstrates that correctly assessing habitat quality in terms of DO requires knowledge of a fish's physiological and environmental history.}, number={2}, journal={JOURNAL OF EXPERIMENTAL MARINE BIOLOGY AND ECOLOGY}, author={Taylor, JC and Miller, JM}, year={2001}, month={Apr}, pages={195–214} }
