Summary
The project estimates the beginning, peak, and ending, of the spawning period and the emergence period of brown trout and optionally landlocked Atlantic salmon in Partakoski, Savitaipale, Southern Finland. The spawning period is estimated by repeated redd counting in October and November 2019. Survival of embryos is estimated by observing the embryos, living or dead, in the redds in April 2020. Some embryos will be sampled and taken to DNA analysis to identify the fish species, i.e. brown trout or salmon. The number of trout and salmon parr has been low in Partakoski, although some tens of redds have been observed in some years in the 2010s.
