Meet Rebecca Krogman - DNR Fisheries Research Biologist
Rebecca earned a MS in Wildlife and Fisheries Science from Mississippi State University and BS in Animal Ecology (Fisheries and Aquatic Sciences) from Iowa State University. She has worked for the Iowa DNR as its reservoir research biologist for 10 years. Prior to that, she served in the same role for the California Department of Fish and Wildlife.
She has published research on the human dimensions of fisheries science and management, engaging underrepresented groups into the outdoors, data and gear standardization, Walleye stocking and population dynamics, catfish sampling and protective regulation, reservoir fish habitat impairment and improvement, and tailwater habitat issues.
Her greatest research passions revolve around fish habitat and integration of social science into fisheries processes. Her best days are either getting slimy or teaching middle-school kids about the outdoors.
Data Set, Graph, Learning Tools
The large reservoirs research team is studying fish health issues in tailwaters below large dams like Red Rock Dam. One of the most prominent fish health issues is gas bubble trauma, a disease similar to “the bends” experienced by SCUBA divers and caused by supersaturation of the water below dams. This issue was studied extensively by Iowa State University in the 1990s leading to some improvements, but not full resolution. Unfortunately, the issue is far more complex than a single factor and the occurrence of disease and related mortality is very difficult to predict. They are studying this fish community and environment weekly throughout the summer and winter to try to determine what those factors are and determine flow management recommendations for the dam operators.
