Assessments of Atlantic salmon stocks of the Maritimes Region, 1998 / T.L. Marshall … [et al.]. : Fs70-1/1999-25E-PDF

This document provides assessments of the Atlantic salmon stocks in more than 40 rivers within the Maritime Provinces. The status of the resource is determined from the annual returns and spawning escapements relative to the conservation requirements, the abundance of juveniles and smolts, corresponding trends in the juvenile stages from measures of sea survival, and the extent of habitat constraints on production. For most of these rivers the probabilities of meeting/exceeding conservation requirements in 1999 and of egg losses for some previously considered management scenarios are also provided. In the absence of river-specific salmon escapement information and where quantitative electrofishing for juvenile salmon has been conducted, the status of stocks were assessed relative to a "normal index of abundance" for the Maritime streams.
