Investigations of the adaptability of two growth groups of coho salmon fry (1+ and 0+) while being transferred from freshwater (FW) into seawater (SW) were performed in the season autumn/winter on four locations (three locations in the Adriatic Sea and one in the FW fish farm, Luknja). Average weight of the 1+ group was 116 g, and average weight of the 0+ group was 86 g. Changes in body composition and condition factor were examined immediately prior to SW transfer, during the early stages of smoltification and for a period of 30 days post-SW transfer. Fish samples (n = 10/time point) were taken in FW, during the transport, and after the transfer into the sea (22.5, 45 and 90 min
