Observations of rainbow trout (Oncorhynchus mykiss) in Newfoundland 1976 to 1999: Fs70-1/2000-043E-PDF

Rainbow trout were successfully introduced into several areas of Newfoundland in the late 1800s and early 1900s. Observations of rainbow trout outside these areas first occurred in 1976 commensurate with the development and expansion of marine cage rearing of rainbow trout elsewhere in Atlantic Canada. The reports of rainbow trout have increased in recent years; as well there has been an increase in the number of rivers where rainbow trout have been observed. Mixed-sex diploid rainbow trout have been identified in rivers with Atlantic salmon populations on the West Coast of Newfoundland. Some of the rainbow trout are believed to be of non-Newfoundland origin. There is concern that new populations could be established and negatively affect the productivity of Atlantic salmon and brook trout.
