Most likely, humans have introduced this type of fish to the Solovetsky lakes, since initially the local ichthyofauna was quite poor. While working on the archipelago, ichthyologists finally clarified that the brown trout (Salmo trutta) has settled on the Bolshoy Solovetsky Island." The scientists conducted a genetic analysis, and prepared a scientific article for the Reports of the Russian Academy of Sciences. The center's Director, corresponding member of the Russian Academy of Sciences, Ivan Bolotov noted that those were the Solovetsky Monastery monks who had planted trout into the archipelago's waters. The Solovetsky trout may be maximum 30-35 cm long.
