Worldwide experience of fish ladders construction as well as juveniles’ downstream migration through dangerous river sections is discussed in respect for artificial Oncorhynchus nerka stock creation for Lake Kronotskoe basin. Basic dimensional parameters of fish ladder were estimated for the Lake Kronotskoe basin according to the recent experience in salmonid ladder building and operation. The assessed parameters are distant to previously proposed ones by TINRO, LenHydroProject, HyproPromRiba. No similar scaled project were realized anywhere in the World. The wide ranges of the complicate issues which are doubt to realize in the current project are determined consequently rising a necessity of the long–term investigations. Ecosystem transformation predictions define the degradation of unique fish fauna after the anadromous Pacific Salmon introduction. The basic ground for the contemporary endemic fauna usage without the anthropogenic impact is suggested in conclusion
