Editing Rainbow trout (section)

==Description==
Resident freshwater rainbow trout adults average between {{convert|1|and|5|lb|kg|round=0.5|order=flip|abbr=on}} in riverine environments, while lake-dwelling, and anadromous forms may reach {{convert|20|lb|kg|0|abbr=on|order=flip}}. Coloration varies widely between regions and subspecies. Adult freshwater forms are generally blue-green or olive green with heavy black spotting over the length of the body. Adult fish have a broad reddish stripe along the lateral line, from gills to the tail, which is most pronounced in breeding males.<ref name=Behnke2002/> The [[Fish fin#AnchCaudal|caudal fin]] is squarish and only mildly forked. Lake-dwelling and anadromous forms are usually more silvery in color with the reddish stripe almost completely gone. Juvenile rainbow trout display parr marks (dark vertical bars) typical of most salmonid juveniles. In some redband and golden trout forms, parr marks are typically retained into adulthood.<ref name=Behnke2002-88>{{cite book |last=Behnke |first=Robert J. |others=Tomelleri, Joseph R.
