✦ Synopsis
A dye process in a textile plant in southern Kentucky (USA) produces large quantities of saline wastewater which eventually enter Lake Cumberland via a municipal sewage treatment plant on Lily Creek . The impact of hypersaline conditions on two fish species native to the Cumberland River drainage system, redbelly dace (Phoxinus erythrogaster) and northern studfish (Fundulus catenatus), was assessed . These species were subjected to salinities of 0, 4, and 10% after which routine oxygen consumption values were determined . Significant correlations of salinity with oxygen consumption were demonstrated for both species with P. erythrogaster showing greater overall impact of salinity on metabolic rate .
