Haro, Alexander

Adjunct Assistant Professor

Ecologist and Section Leader, Fish Passage Engineering
S.O. Conte Anadromous Fish Research Center

Phone: 413-863-3806

Primary interests

Dr. Haro’s interests include behavior and biology of diadromous fishes, fish passage biology and engineering, and animal migration. Current research involves biotic and abiotic influences on fish migration, design and performance of traditional and experimental fish passage structures, development of new technologies for assessment of fish behavior and passage, and behavior of upstream and downstream migrant diadromous fishes.


Current Projects 

  • Development of advanced telemetry systems for monitoring fish migration and movements

  • Effect of temperature, light, water velocity, turbulence, and air entrainment on behavior and passage of adult and juvenile diadromous fishes

  • Burst swimming performance of diadromous fishes in high velocity, turbulent flow

  • Riverine movements and passage of American eels

Courses Taught:

  • OEB 697A/WFCON 491 – Animal Migration and Movement
  • WFCON 697G – Ecology of Diadromous Fishes (team taught)
