Review of existing scientific literature pertaining to fish mortality and its population-level impacts at the Annapolis Tidal Hydroelectric Generating Station, Annapolis Royal, Nova Scotia. : Fs70-6/2019-055E-PDF

"The Annapolis Tidal Generating Station (Annapolis TiGS) is located in the Annapolis River estuary in Annapolis Royal, Nova Scotia, Canada. It has been in operation since 1985. It is the first tidal hydroelectric generating station constructed in North America. The operation of the Annapolis TiGS is known to cause mortality of some fish within the Annapolis River estuary, and there is potential for these mortalities to have population-level effects. Fisheries and Oceans Canada (DFO) Ecosystem Management Branch requested that a review of existing scientific literature pertaining to the Annapolis TiGS be undertaken to provide a better understanding of whether the current operation of the TiGS is in compliance with the Fisheries Act and the Species at Risk Act. The objectives of this report, undertaken to fulfill this request, are to provide an evaluation of the published information about the fish community in the vicinity of the Annapolis TiGS, fish passage and fish mortality at the Annapolis TiGS, and population-level impacts associated with this mortality. The information in this report is intended to inform regulatory decisions under the Fisheries Act and Species at Risk Act"--Context (page [1]).
