Vicki S. Blazer, PhD
Vicki startted with the National Fish Health Research Laboratory, Leetown Science Center (now the Eastern Ecological Science Center - Leetown Research Laboratory), Kearneysville, WV in1992. She was previously employed as the Assistant Leader of the Georgia Cooperative Fish and Wildlife Research Unit. She was also on the graduate faculty in the School of Forest Resources, University of Georgia.
She is active in numerous research projects within the Northeast as well as nationally and internationally. She is active in the American Fisheries Society Fish Health Section and a member of other scientific societies. She is an adjunct faculty member at West Virginia University and Penn State and serves on graduate student committees. Research areas include development of microscopic and molecular markers for understanding changes in the health and populations of wild fishes. Areas of focus include endocrine disruption, emerging diseases, fish tumor pathology and assessment at Great Lakes Areas of Concern, land use influences on fish health, reproduction and immunomodulation.

Aphanomyces as a cause of ulcerative skin lesions of menhaden from Chesapeake Bay Tributaries Aphanomyces as a cause of ulcerative skin lesions of menhaden from Chesapeake Bay Tributaries
During the summer and fall of 1997, an unusually high prevalence of skin lesions in fishes from Chesapeake Bay tributaries as well as two fish kills in the Pocomoke River stimulated significant public concern. Atlantic menhaden Brevoortia tyrannus were the most frequent target of the acute fish kills and displayed skin lesions that were attributed to the presence of the toxic...

Biomonitoring of Environmental Status and Trends (BEST) Program: Field Procedures for Assessing the Exposure of Fish to Environmental Contaminants Biomonitoring of Environmental Status and Trends (BEST) Program: Field Procedures for Assessing the Exposure of Fish to Environmental Contaminants
This document describes procedures used to collect information, tissues, and fluids for documenting the exposure of fish to environmental contaminants. For the procedures described here, fish are captured (preferably by electrofishing) and held alive until processing (generally

Contaminant exposure, biochemical, and histopathological biomarkers in white suckers from contaminated and reference sites in the Sheboygan River, Wisconsin Contaminant exposure, biochemical, and histopathological biomarkers in white suckers from contaminated and reference sites in the Sheboygan River, Wisconsin
Fish populations of the lower Sheboygan River, located in east-central Wisconsin, are considered impaired under the Great Lakes Water Quality Agreement between the United States and Canada. Pollutants in the Sheboygan River system include: polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and heavy metals. This study compared general health and biochemical...

Effects of ultraviolet-B radiation on fish: Histologic comparison of a UVB-sensitive and a UVB-tolerant species Effects of ultraviolet-B radiation on fish: Histologic comparison of a UVB-sensitive and a UVB-tolerant species
Lahontan cutthroat trout Oncorhynchus clarki henshatvi were sensitive to simulated solar ultraviolet-B radiation (UVB) and exhibited grossly visible signs of sunburn upon exposure. Razorback suckers Xyrauchen texanus, however, were tolerant to simulated solar UVB and showed no grossly visible signs of exposure. Cutthroat trout also had considerably less of an unidentified, possibly...

Effects of dietary lipid on the hematology of channel catfish, Ictalurus punctatus Effects of dietary lipid on the hematology of channel catfish, Ictalurus punctatus
Juvenile channel catfish were fed diets containing either soybean oil, menhaden oil, beef tallow, or a combination of these three lipid sources. After 90 days, total erythrocyte, leucocyte, and thrombocyte counts, hematocrit, mean corpuscular volume, plasma recalcification time, erythrocyte osmotic fragility, total serum iron, and iron-binding capacity were measured. Total erythrocyte...

Hepatic neoplasms in wild common carp Hepatic neoplasms in wild common carp
Common carp Cyprinus carpio from West Point Lake, Georgia-Alabama, were sampled (N = 81) during fall 1991. Gross examination revealed single nodules in the livers of four fish; representative tissues from all sampled fish were preserved for histological examination. One of the four nodules was a hepatocellular adenoma and the other three were hepatocellular carcinomas. Two additional...

Influence of fish oils in production catfish feeds on selected disease resistance factors Influence of fish oils in production catfish feeds on selected disease resistance factors
Healthy channel calfish, Ictalurus punctatus (mean weight: 62.5g), were fed two production feeds that were identical except for the lipid portion, which was either catfish oil or menhaden oil. Fish were held at 18 or 28°C and fed the experimental feeds for four monlhs. A subsample of fish from each of the four treatments was then used to measure scrum antibody titers to Edwardsiella...

Malignant lymphoma in black bullhead from Allouez Bay, Superior, Wisconsin, USA Malignant lymphoma in black bullhead from Allouez Bay, Superior, Wisconsin, USA
Leukemic malignant lymphoma was diagnosed in a black bullhead collected from Allouez Bay, in an industrialized Lake Superior estuary near Superior, Wisconsin, USA. No gross signs of thymic involvement were observed and it is believed this tumor originated in the hematopoetic tissue of the kidney. Neoplastic cells infiltrated excretory kidney, spleen, liver and gill tissue. This finding...
