Abstract

In insular Newfoundland, wild anadromous juvenile Atlantic salmon make extensive use of lacustrine habitat for rearing. Smolt production was determined for a portion of a river system where virtually all rearing habitat is lacustrine. Production in terms of lacustrine habitat was estimated to be 10.1 smolts- ha−1. Smolt production is discussed in relation to morphometric characteristics. A comparison is made with smolt production obtained from stockings of swim-up fry directly into lakes in another insular Newfoundland river system.
