No abstracts are to be cited without prior reference to the author.The M74 mortality has existed at different levels in the offspring of feral Baltic salmon spawners; between populations, and even within the same population the share of females producing M7 4 offspring varies \lidely. According to the tag recovery data the main feeding areas in the Baltic Proper are located in the surroundings of the Bomholm Deep and Gotland Deep, but salmon also feed in the Bothnian Sea and Gulf of Finland. The distribution of the salmon feeding in these areas varies between populations but also between individuals belonging to the same population. The size of salmon smolt entering the sea varies between 12 and 20 cm within a population when dealing with wild populations and between 14 and 25 cm within hatchery-reared smolt. The length of wild smolt has been, on average 16cm during the 1990s while hatchery-reared smolt have been about 20 cm in the Gulf of Bothnia area. Availability of a suitable size of feed and /or ...
