Jacob Krause, Ph.D.

As our access to aquatic resources become increasingly complex, my research aims to provide managers with the knowledge to make wise and informed decisions. My investigations are focused on understanding fish population dynamics through field observations and robust mathematical modeling.

I work at the Klamath Falls Field Station as a Research Fish Biologist. My current work focuses on the challenges of recovering the endangered Lost River and shortnose suckers in the Upper Klamath River Basin, through monitoring their population dynamics and investigating potential barriers to recruitment. My postdoctoral studies included analyzing the effects of hypoxia on the shrimp fishery of the Gulf of Mexico, and using telemetry to estimate mortality within the cobia fishery, an important recreational species in the Southeast Atlantic. For my doctoral research project, I spent six years determining the sources, magnitude, and timing of weakfish mortality across the Atlantic Coast using telemetry, conventional tagging, and predator-prey models. I developed an Index of Biotic Integrity (IBI) for prairie streams of South Dakota for my Master’s thesis, and have been involved in coral reef monitoring on the island of Grenada, lake management plans to mitigate invasive aquatic plants in the Midwest, and maintaining Lake Michigan’s power plants’ compliance to EPA’s 316 (b) mandate.

Research interests:

I enjoy conducting applied fisheries research that informs sound management decisions. I am interested in learning about established methods used in fisheries management, such as mark-recapture and population indices, and am always keen to improve on existing knowledge. I frequently work with collaborators across multiple institutions to address topics of interest in both marine and freshwater environments.

My skillset includes using telemetry, conventional tagging, experimental research designs, and interpreting long-term monitoring data, to better understand the abiotic and biotic barriers to fish population recovery. In addition to traditional field observations, I am experienced in quantitative analysis, including hierarchical models across multiple statistical frameworks, mark-recapture, predator-prey interactions, simulations, and writing R code.
