Jonsson, B Freshwater biology. Oxford [FRESHWAT. BIOL.]. Vol. 21, no. 1, pp. 71-86. 1989. Brown trout (Salmo trutta ) life history and habitat use were studied in two Norwegian rivers: The Vosso river system, western Norway, and the Soere Osa, eastern Norway. Age-groups were partly segregated in feeding habitats, the youngest fish living mainly in running water and in the littoral zone of lakes, the older fish also exploiting pelagic waters and deeper epibenthic habitats. Within local populations, females were larger and less variable in size than males. Within age-groups, females were more pelagic and migrated more than males, whereas males were more confined to running water and epibenthic areas than females.
hmm, i almost want to know more- scandinavian queen.
