Our team of fisheries research scientists and technicians produces objective, applicable science for Fisheries Management and DNR customers. Our staff works with Wisconsin sportfishes and specializes in areas including applied fisheries management and ecology, quantitative stock assessments, fish habitat, propagation science and population dynamics.

We conduct our projects out of three research stations across the state (Boulder Junction, Madison and Spooner) to cover the diversity of Wisconsin’s aquatic habitats and species.
