Brown
Trout

An introduced species the Brown Trout is still actively stocked for angling purposes, despite the fact that it severely impacts native aquatic species. Some fish find their way to the sea, mainly inhabiting estuarine and shallow coastal waters. Colour variable, and influenced by age, habitat and diet. In a marine environment they change colour to much more silvery overall and have a few indistinct spots. Breeding male has enlarged jaws with tip of lower jaw forming a hook

Moderately deep, torpedo-shaped body with a large terminal mouth extending slightly obliquely to below the eyes. Short-based dorsal fin high on back originating in front of ventral fins; fleshy adipose fin behind dorsal. Colour variable, usually brown or olive with dark spots on the sides, dorsal fin and gill covers. Tail with few if any spots. Body paler below mid-line, and most spots surrounded by a pale halo and often reddish.
