| bioaccumulation of stentorin, the probable causative agent for discolored ("purple") eggs and ovaries in blue catfish (ictalurus furcatus) from eufaula lake, oklahoma, usa. | observations of reddish to "purple" discolored eggs in the ovaries of adult female blue catfish (ictalurus furcatus) from the northern arm of eufaula lake, a eutrophic multiuse impoundment in east-central oklahoma, were first reported in 2006. blue catfish eggs are normally cream to light yellow. reports peaked in 2007-2008 and declined through 2009-2010; purple eggs have not been reported between 2010 and 2014. in the laboratory, all tissues and fluids of affected fish were strongly orange-red ... | 2015 | 26230836 |
| a screening-level assessment of lead, cadmium, and zinc in fish and crayfish from northeastern oklahoma, usa. | the objective of this study was to evaluate potential human and ecological risks associated with metals in fish and crayfish from mining in the tri-states mining district (tsmd). crayfish (orconectes spp.) and fish of six frequently consumed species (common carp, cyprinus carpio; channel catfish, ictalurus punctatus; flathead catfish, pylodictis olivaris; largemouth bass, micropterus salmoides; spotted bass, m. punctulatus; and white crappie, pomoxis annularis) were collected in 2001--2002 from ... | 2006 | 16791710 |
| biochemical effects of lead, zinc, and cadmium from mining on fish in the tri-states district of northeastern oklahoma, usa. | we assessed the exposure of fish from the spring and neosho rivers in northeast oklahoma, usa, to lead, zinc, and cadmium from historical mining in the tri-states mining district (tsmd). fish (n = 74) representing six species were collected in october 2001 from six sites on the spring and neosho rivers influenced to differing degrees by mining. additional samples were obtained from the big river, a heavily contaminated stream in eastern missouri, usa, and from reference sites. blood from each fi ... | 2005 | 16117126 |
| concentrations of cadmium, lead, and zinc in fish from mining-influenced waters of northeastern oklahoma: sampling of blood, carcass, and liver for aquatic biomonitoring. | the tri-states mining district (tsmd) of missouri (mo), kansas (ks), and oklahoma (ok), usa, was mined for lead (pb) and zinc (zn) for more than a century. mining ceased more than 30 years ago, but wastes remain widely distributed in the region, and there is evidence of surface- and groundwater contamination in the spring river-neosho river (sr-nr) system of northeastern ok. in october 2001, we collected a total of 74 fish from six locations in the sr-nr system that included common carp (cyprinu ... | 2005 | 15981034 |
