BK-Riverfish LLC is an environmental consulting business focused on migratory fish behavior, ecology, and fish passage. It is staffed by Boyd Kynard, PhD in Fish Biology, Univ. of Washington, Seattle, WN, in 1971, and by his son, Brian Kynard, BS in Biology, Univ. of Massachusetts, Amherst, in 2006. At the University of Massachusetts and at the S. O. Conte Anadromous Fish Research Center (USGS), Turners Falls, MA, Boyd spent 40 years studying behavior, ecology, and fish passage of migratory fish, including the endangered shortnose sturgeon, in the Connecticut River, particularly in the Massachusetts reach. Boyd has an international reputation having studied riverine fish migration in Brazil, China, and Romania. Brian has 25 years working for the Natural Resources Department, Univ. of Massachusetts, Amherst, as a Technician or Project Leader on diverse field and laboratory research on Connecticut River migratory fish, including shortnose sturgeon, and on field and artificial stream studies on ecology of white sturgeon in the Kootenai River, Idaho-Canada. Both Boyd and Brian have taught nature, swimming, and canoeing classes to middle and high school students. BK-Riverfish has a fish behavior/hydraulics lab in Erving, MA, on the Millers River that will be the site of artificial stream trials and data analyses.
