Research Overview

My primary interests are teaching and research in biology of marine fishes. Courses taught include Ichthyology, Biology of Commercially Important Marine Fishes, Fish Ecology, and Early Life History of Marine Fishes. Supervised research of graduate students has been on the biology of commercially important marine fishes and on the ecology of larval fishes in subarctic marine systems.

My research interests include ecological relationships and population dynamics of nearshore fish pop-ulations, with an emphasis on arctic fishes and subarctic rocky-reef communities. Other research is focused on the study of early life history of marine fishes, with emphasis on larval ecological relationships. Apparently, most of the variation in year class strength of marine fish species results from differential mortality during the egg and larval stages. Studies are being conducted to determine the effects of prey availability on growth and survival of selected marine larval fishes.
