“…Concentrations in two male carp from Station 511 were within the range of early-to mid-vitellogenic females (Table 6), a condition that has been associated with the exposure of male fish to exogenous estrogens in both field and laboratory studies (e.g., Folmar et al, 1996Folmar et al, , 2001Gimeno et al, 1997;Jobling et al, 1998). In addition, and keeping with the findings of most field studies (e.g., Goodbred et al, 1997;Lee et al, 2000;McDonald et al, 2002;Solé et al, 2002Solé et al, , 2003, none of the vitellogenic male carp were intersex. These findings contrast with those of a study of reproductive biomarkers in another European cyprinid (roach, Rutilus rutilus) collected near sewage treatment plants in which the proportion of intersex fish and the severity of the intersex condition were greater than reference fish, and the mean vtg concentration of the intersex males was intermediate between that of males and female controls .…”

“…Ovotestis was detected in male bass from Stations 16, 512, and 513, and exclusively in largemouth bass; however, only one male smallmouth bass (from Station 514) was examined. In the MRB, ovotestis was detected in male bass of both species, but a high percentage (N50%) of affected fish was only observed in smallmouth bass at one site and none were detected in carp (McDonald et al, 2002). Baldigo et al (2000) detected similar percentages of both largemouth and smallmouth bass at some Hudson River (New York) sites, but no intersex males were reported among the largemouth bass exposed to paper mill effluents by Sepú lveda et al (2001Sepú lveda et al ( , 2003.…”

“…Mean Se concentrations in fish from Stations 65, 514, and 515 and individual fish from several other sites exceeded these criteria. The toxicity of Se may be mediated somewhat by dietary As (Hamilton et al, 2002). Concentrations of both As and Se are naturally elevated in some parts of the RGB and may be further increased by leaching due to irrigation, and both As and Se are released during the combustion of fossil fuels.…”

“…Reproductive biomarker measurements of note were determined primarily through comparison with the 1995 MRB study (McDonald et al, 2002) and the literature; McDonald et al (2002) documented the importance of controlling for stage differences in such comparisons. Both male and female carp from Station 511 (AC at Harlingen, TX) were in earlier gonadal stages and had lower GSIs than those from all other stations, probably because they were collected several weeks before all other stations in the lower RGB.…”

Dethloff, Gail M.; Bartish, Timothy M.; Coyle, James J.; and Tillitt, Donald E., "Environmental contaminants and biomarker responses in fish from the Rio Grande and its U.S. tributaries: Spatial and temporal trends" (2005 AbstractWe collected, examined, and analyzed 368 fish of seven species from 10 sites on rivers of the Rio Grande Basin (RGB) during late 1997 and early 1998 to document temporal and geographic trends in the concentrations of accumulative contaminants and to assess contaminant effects on the fish. Sites were located on the mainstem of the Rio Grande and on the Arroyo Colorado and Pecos River in Texas (TX), New Mexico (NM), and Colorado. Common carp (Cyprinus carpio) and largemouth bass (Micropterus salmoides) were the targeted species. Fish were examined in the field for internal and external visible gross lesions, selected organs were weighed to compute ponderal and organosomatic indices, and samples of tissues and fluids were obtained and preserved for analysis of fish health and reproductive biomarkers. Whole fish from each station were composited by species and gender and analyzed for organochlorine chemical residues and elemental contaminants using instrumental methods, and for 2,3,7,8-tetrachloro dibenzo-p-dioxin-like activity (TCDD-EQ) using the H4IIE rat hepatoma cell bioassay. Overall, fish from lower RGB stations contained greater concentrations of organochlorine pesticide residues and appeared to be less healthy than those from sites in the central and upper parts of the basin, as indicated by a general gradient of residue concentrations and biomarker responses. A minimal number of altered biomarkers and few or no elevated contaminant concentrations were noted in fish from the upper RGB. The exception was elevated concentrations [up to 0.46 Ag/g wet-weight (ww)] of total mercury (Hg) in predatory species from the Rio Grande at Elephant Butte Reservoir, NM, a condition documented in previous studies. Arsenic (As) and selenium (Se) concentrations were greatest in fish from sites in the central RGB; Se concentrations in fish from the Pecos River at Red Bluff Lake, TX and from the Rio Grande at Langtry, TX and Amistad International Reservoir, TX exceeded published fish and wildlife toxicity thresholds. In the lower RGB, residues of This article is a U.S. government work, and is not subject to copyright in the United States.p,pV-DDT metabolites (V1.69 Ag/g ww), chlordane-related compounds (V0.21 Ag/g ww), dieldrin (V0.0.05 Ag/g ww), and toxaphene (V2.4 Ag/g ww) were detected in fish from most sites; maximum concentrations were in channel catfish (Ictalurus punctatus) from the Arroyo Colorado at Harlingen, TX. Concentrations of one or more residues exceeded toxicity thresholds for fish and wildlife in fish from this site and from the Rio Grande at Mission, TX and Brownsville, TX; however, concentrations were lower than those reported by previous studies. In addition, the proportional concentrations of p,pV-DDT at all sites were low, indicating weathered DDT rather than the influx of new ma...

Phytochelatin induction by selenate in Chlorella vulgaris, and regulation of effect by sulfate levels

Phytochelatins (PCs) are short metal detoxification peptides made from the sulfur-rich molecule glutathione. The production of PCs by algae caused by Se exposure has never been studied, although many algae accumulate Se, forming Se-rich proteins and peptides, and higher plants have demonstrated PC production when treated with Se; therefore, a goal of the current study was to examine whether Se induces PC production in algae. Furthermore, selenate is thought to compete with sulfate in the S assimilation pathway, and sulfate therefore may have a protective effect against the toxic effects of high doses of Se in algae. Hence, the interaction of selenate and sulfate was investigated with respect to the induction of PCs. Chlorella vulgaris was cultured in media with either low (31.2 µM) or high (312 µM) concentrations of sulfate. These cultures were exposed to selenate in doses of 7, 35, and 70 nM for 48 h. In a separate treatment, Cd (890 nM) was added as a positive PC-inducing control, and one no-metal negative control was used. Total Se and Se speciation were determined, and glutathione, phytochelatin-2, and phytochelatin-3 were quantified in each of cell digests, cell medium, and cell lysates. We found that PCs and their precursor glutathione were induced by selenate as well as by a Cd control. The high concentration of sulfate was able to counter selenate-induced production of PCs and glutathione. These data support two possible mechanisms: a negative feedback system in the S assimilation pathway that affects PC production when sulfate is abundant, and competition for uptake at the ion transport level between selenate and sulfate.

The aim of this study was to investigate the interactive effects of temperature and dietary selenium concentrations on antioxidant capacity, muscle histochemistry and the growth, of juvenile yellowtail kingfish (Seriola lalandi). The yellowtail kingfish were exposed to two temperatures (21C or 26C) and three selenium levels (0.0, 2.0 or 4.0 mg Se kg −1 of feed) for 30 days. Final weight and specific growth rate (SGR) were significantly affected by water temperature (ρ<0.001) and dietary Se (ρ<0.001) supplementation, and there were significant differences in the interaction between these two factors. Juvenile yellowtail kingfish fed Sesupplemented diets, attained a higher final weight and SGR than those without Se supplementation at 21C, but not at 26C. Regardless of the temperature, the red blood cell (RBC) glutathione peroxidase (GPx) activity of yellowtail kingfish fed Se-supplemented diets was significantly higher (ρ<0.05) than with the control diet. However, GPx activity of yellowtail kingfish when fed either 2.0 mg Se kg −1 or 4.0 mg Se kg −1 showed no significant difference (ρ>0.05). Se concentration in the muscles of juvenile yellowtail kingfish fed Se-supplemented diets was higher than that of the yellowtail kingfish that were fed the control diet. A histopathological test confirmed that 20.3% of fish muscles exhibited lesions, which occurred in the absence of dietary Se. The outcome of the present study helps in understanding the interactive effects of dietary Se concentrations and the temperature in the farming of yellowtail kingfish.
