The area under investigation and the location of the reproduction sites, where the temperature dynamics was analyzed ( a positions of the spawning grounds for fish sampling are put in colour); the adult fish external appearance ( b maximal (mean) fork length is shown for the morphs, Dolly Varden’s fork length–for the river where the spawners were caught (Kamchatka River, above), and for the Kronotskaya River population (below)).
