Primary interests

Dr. McCormick’s research examines environmental and endocrine control of
osmoregulation, growth and development in teleosts, primarily anadromous
fishes. His current research focuses on physiological and enviromental
factors that affect conservation, restoration and enhancement of Atlantic
salmon, American shad and Atlantic sturgeon. This includes laboratory and
field work on underlying physiological principles, and applied work with
pollution, hatcheries, dams and with wild populations.

Current Projects

  • Environmental and hormonal control of the parr-smolt transformation of
    Atlantic salmon.

  • Contaminants that act as endocrine disruptors of the parr-smolt

  • Gill tranport proteins involved in ion regulation of euryhaline fish.

  • Impact of acid and aluminum on salinity tolerance of Atlantic salmon.

  • Effects of fish ladders on stress, fatigue and reproductive success of
    adult American shad.
