- Abstract
An Atlantic salmon Salmo salar enhancement program has been in progress on the Exploits River, Newfoundland, since 1957. Prior to enhancement, approximately 10% of the total watershed area was accessible to anadromous Atlantic salmon compared to around 50% at present. Adult returns have increased substantially since the commencement of enhancement activity. Two methods of introduction were employed. One involved stocking with adults and the other stocking with swim-up fry from a controlled-flow, artificial spawning channel and two deep-substrate, upwelling incubation boxes. Both methods were evaluated in terms of adult returns. Results indicated that fry stocking was the most effective approach. Fry stocking resulted in the establishment of runs in Exploits River tributaries in roughly one-half the time required for adult stocking and with less than one-half the brood-stock requirement.
