Fish passage requirements for rainbow smelt (Osmerus mordax) and gaspereau (alewife Alosa pseudoharengus and blueback herring A. aestivalis) at fishways and culverts: Fs97-6/3210E-PDF

current knowledge, research gaps, and recommendations /

“Historically, the design of fish passage structures such as fishways and culverts has focused on passing salmonids. Recently, however, increasing emphasis is being placed on passing non-salmonid species that are less proficient at ascending obstacles. In the Canadian Maritime Provinces, determining what factors facilitate passage of Rainbow Smelt (Osmerus mordax) and Gaspereau (collectively Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis), species of particular economic and cultural importance. This report presents fish passage information for Rainbow Smelt and Gaspereau for four topics: 1) passage performance of different fishway and culvert designs; 2) swimming performance; 3) life history and behavioural considerations; and 4) physiological considerations”--Abstract, p. v.
