The progeny of salmon, Salmo salar L., kelts reconditioned in fresh water for one and two years were stocked in the spring as swim‐up fry into good salmonid habitat in 1993 and 1994. Survival to the first summer was compared with that of control groups. There was no significant difference ( P > 0.4) between the average number of reconditioned kelt and control fry caught per five‐minute semiquantitative electric fishing for the two years. Transformation of semiquantitative electric fishing results showed that average survival rates were about 24% and 30% for reconditioned kelt progeny and their controls, respectively, in 1993, and about 34% for both groups in 1994.
