. Post‐spawning Atlantic salmon. Salmo salar L ., were obtained from a salmon enhancement project in the autumn of 1984, These salmon were overwintered in submerged cages in fresh water, retrieved in the spring of 1985, and transferred to a marine cage after vaccination for Vibrio anguillarum . Salmon mortality was highest immediately after their retrieval from overwintering cages, Mortality through the duration of the marine cage interval was 0.22% per day. Growth reached a maximum of 1.76% per day. Average final weight reached by reconditioned kelt in the 101 days of marine cage confinement was greater than the average weight of natural repeal spawners in the stock that provided kelt to the aquaculture experiment. Reconditioned salmon were slaughtered in November and marketed, both fresh and smoked. The incidence of maturation among slaughtered salmon was less than 2%. Consumer response to reconditioned kelt indicated that flesh colour was inferior but thai the products were acceptable and that 84% of the consumers polled would purchase the product again.
