Mactaquac Dam, New Brunswick gaspereau report 2019 / by Robert Beaumaster, Lei E. Harris and Leroy Anderson. : Fs97-13/1301E-PDF

"In 1989, in consultation with stakeholders, Fisheries and Oceans Canada (DFO) agreed to annually transport one million gaspereau (Alewife (Alosa pseudoharengus) and Blueback Herring (Alosa aestivalis)) from the St. John River, NB, around the Mactaquac Dam and release them in the headpond. Once the annual gaspereau escapement program commenced, three staff worked 12 hours per day, seven days per week, until escapement targets of 800,000 Alewives and 200,000 Blueback Herring were met. Following a reduction in effort to 10 hours per day, six days per week in 2012, the Blueback Herring minimum escapement target was met each year, but the Alewife target was only met in 2014 and 2015. In 2018 and 2019, when the schedule was returned to three staff working 12 hours per day, seven days per week, targets for both species were met. To reach the 800,000 Alewives and 200,000 Blueback Herring escapement targets, schedule a crew of three trained staff per day (two of them as truck drivers) to work for 12 hours per day, seven days per week, with uninterrupted operation of the Mactaquac Fish Collection Facility for the duration of the gaspereau escapement program"--Abstract.
