The project studies migration and fishing mortality of brown trout in the Kymijoki watershed and especially in the Rautalampi watercourse by tagging and ultrasound telemetry. Second, the reproduction ecology of trout and landlocked salmon is studied. The timing and length of the spawning period and the emergence period, and the stock-recruitment ratio, are estimated. Third, the project estimates the size of spawning stocks of brown trout and landlocked salmon, and the effects of fishing mortality on the stocks, in the Vuoksi watershed, Lake Päijänne, Lake Vättern, and Lake Vänern.
