Summary

Lake Mead National Recreational Area (LMNRA) serves as critical habitat for several federally listed species and supplies water for municipal, domestic, and agricultural use in the Southwestern U.S. Contaminant sources and concentrations vary among sub-basins within LMNRA. To investigate whether environmental contaminant exposure is associated with alterations in male common carp (Cyprinus carpio) gamete quality and endocrine- and reproductive parameters, data were collected among sub-basins (n = 7) over 7 years (1999 to 2006). Endpoints included the sperm quality parameters of motility, viability, mitochondrial membrane potential, count, morphology, and DNA fragmentation; plasma components were vitellogenin (VTG), 17ß-estradiol, 11-keto-testosterone, [...]

Purpose

Understanding the effects of endocrine disrupting compounds in the major sub-basins in the LMNRA is key to water-resource management, especially in light of the continued reductions of Colorado River flow and lowering lake levels. Changes at the hormonal, cellular and molecular level precede changes at the organ and organismal level, thus sperm biomarker assays were established and used here to complement other biomarkers more conventionally used in field EDC studies. In addition to analytical chemistry results, these endpoints provided information on fertility of fish and reproductive potential of populations in the ecosystem. A retrospective evaluation of data collected, and consequent temporal trends, occurring in this reservoir were presented, and a synthetic design is offered for studies of environmental endocrine disruption. Future LMNRA studies are relevant as drought conditions, the concentration of water-borne chemicals, and projected urban growth in the Virgin River watershed near Overton Arm.
