Lake Thingvallavatn – Big Brown Trout
The brown trout in Lake Þingvallavatn, whose origin can be traced to Britain, has long been one of the most talked-about freshwater fish in Iceland - and abroad. The brown trout's fame is based primarily on its large size and great numbers. After it became isolated in Þingvallavatn in the wake of the last ice age, living conditions proved beneficial, and it was found in many populations all over the lake.
