| Summary: | This report summarizes some of the probable negative effects of a tidal power barrage in the upper Bay of Fundy on the passage and hence maintenance of anadromous fish in freshwater streams embraced by the development. The predicted negative impacts are based mainly on supporting research conducted in freshwater and estuarine situations, since studies of fish passage at marine obstructions are lacking. Probable negative impacts on anadromous fishes include: delayed or failed passage, straying from native rivers, mortality of large adults in turbines (particularly if re-cycling is high), decreased passage time at tidal aboiteaux, and loss of spawning and rearing habitat through inundation if peripheral pumped stor-age facilities are constructed. It is speculated that the overall success of maintaining passage of anadromous fishes into the tidal headpond and its freshwater tributaries will likely be determined by the ultimate placement and relationship of the sluice (both in plan and elevation) and hydroelec-tric turbines. |
