- Physiological Ecology of Fishes
- Fisheries Management
My research interests are relatively diverse including ecology, physiological ecology, systematics, and management of fishes. I have developed an integrated field/laboratory approach to the study of fish biology. I have found that the combination of these diverse approaches has yielded insight into broader theoretical problems of biology and new approaches for management of fishes.
I have developed some theoretical models which describe behavioral responses of fishes to temperature as functions of physiological and thermodynamic processes. I have set up a laboratory equipped to test predictions of these models. This work has implications for identifying and measuring environmental optima and subsequently insight into the distribution and abundance of organisms.
I am also involved in studying fish ecology in the field. This ranges from basic research in fish ecology to applied research in fisheries management.
Field and laboratory research each enhance the other. Difficult field questions may be simplified when translated to the laboratory setting and also may suggest theoretical models to be tested. Laboratory research may suggest new approaches for fisheries management.
Currently, I am involved in studying maximum critical swimming speeds of fishes as a function of parasite load. I am testing whether swimming speed is a good measure of surplus power available to a fish under a given thermal regime.
