A framework for the assessment of the status of river herring populations and fisheries in DFO’s Maritimes Region / A. Jamie F. Gibson, Heather D. Bowlby, and Freya M. Keyser. : Fs70-5/2016-105E-PDF
“Alewife (Alosa pseudoharengus) and blueback herring (Alosa aestivalis) are diadromous species of fish that are collectively referred to as river herring. River herring return to many of the river systems in Nova Scotia and Southwest New Brunswick and are fished together as “gaspereau”. The fishery is geographically widespread, with fishing practices and gear types that differ among rivers, and is managed primarily through effort controls. Within the Maritimes Region, the status of river herring stocks has not been regularly assessed. Towards the goal of developing an on-going monitoring and assessment program, this framework was developed to provide an overview of the spatial scale for assessment and identification of stock units, reference points against which status could evaluated, monitoring methods, analytic methods and research recommendations, taking into account DFO’s precautionary framework for fisheries management"--Abstract, p. v.
