Abstract
Abstract Artificial reconditioning of Atlantic salmon in fresh water over two successive years produced kelt survival rates of 28% and 55% in years one and two, respectively. Eye damage and failure to identify non‐feeders were important factors contributing to high mortalities. Average fecundities of kelts reconditioned for the first (1220 ova kg‐1) and second (1093 ova kg‐1) year were lower than obtained for virgin control fish (1590 and 1728 ova kg‐1 respectively). Average survival to swim‐up for progeny of first‐year (64.5%) and second‐year (71.4%) reconditioned fish were similar to survival of virgin control fish progeny (72.3% and 68.9% respectively).Ranched kelts showed better growth parameters than for freshwater reconditioning but had lower average fecundities (1310 ova kg‐1 compared with 1820 ova kg‐1) and lower average progeny survival to swim‐up (60.8% compared with 88.6%) than their control group.
