Students' Professional Biography
Andy is currently a senior at Minnesota State University Mankato. Andy anticipates graduating in the spring of 2013 with a B.S in Environmental Science with a focus in aquatic ecology, and minors in biology and law enforcement. Andy is currently involved with the Water Resources Center as a work study intern and has been involved with them since summer of 2011. He has recently completed an internship working for the Streams Habitat Program with the Minnesota Department of Natural Resources. His involvement includes the National Biological Honor Society, American Fisheries Society, campus volunteer and Dean’s list member. He will be presenting his research project at the Midwest Fish and Wildlife conference 2012 in Kansas this fall with Paul Pallardy Jr. Andy is planning on attending graduate school in the fall of 2013 and pursuing a career in either fisheries or environmental consulting. Paul is completing his final year at Minnesota State University, Mankato. Paul’s anticipated graduation date is May 11, 2013 with a degree in Environmental Science with a focus in toxicology, minors in both Biology and Geography, and a GIS certificate. His research on this project was conducted during the 2011-2012 school year. For the past three summers Paul has held an intern position with Weaver Boos Environmental Consulting Firm in Chicago, Illinois. His experience with the firm has included water and soil sampling. Paul is looking to pursue a career in environmental consulting.

Abstract
Concern has been noted by fish hatchery biologists with the Department of Natural Resources that southern Minnesota northern pike Esox lucius populations have exhibited reduced hatching rates, a trend not occurring with northern Minnesota pike populations. The chemical atrazine is a frequently used herbicide in Minnesota and has been found to cause gonadal dysgenesis and reproductive development issues in amphibians and fish. Sperm, length, and age data were collected from northern pike in four Minnesota lakes. Water samples were obtained from two of the lakes to test for atrazine. Test results indicated atrazine concentrations0.10 and r2 < 0.06 for all regressions). Sperm motility reductions in northern pike could be related to declining populations and warrants further research.
