density

Aeration can circulate waters by disrupting thermal density differences associated with stratification, allowing homogenization of tempera- ture, oxygen, and other physicochemical characteristics within the water body. Use of lake and pond destratification as a management tool has been increasing in recent years, yet data are limited regarding its effects on fish communities. This case study examines the response of a largemouth bass (Micropterus salmoides) population to destratification in a 2.4-ha pond over nearly a decade. Biomass (35.8–42.8 kg ha–1) and density (51–93 fish ha–1) of...

Recreational flow releases were established within the Nantahala Bypass Reach through the Federal Energy Regulatory Commission relicensing of Duke Energyâ??s Nantahala Project. In 2012-2013, the North Carolina Wildlife Resources Commission, in conjunction with other resource managers, attempted to monitor the influence of recreational flow events on wild rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta) populations within Nantahala Bypass Reach and Nantahala Tailwater. Monitoring included temperature loggers and fish population sampling. Temperature effects of release...
