Trout and Trout Fishing in the UK
The Trout family in the UK
Another species that is popular within the UK is the Rainbow Trout [oncorhynchus mykiss] The Rainbow Trout is a salmonid and is native to the tributaries of the Pacific Ocean and in North America, the rainbow or Steelhead as it is known is a very popular sport fish. The Steelhead is a sea-run fish [anadromous] and returns to freshwater to spawn just like the UK’s Sea Trout. The Steelhead usually returns to freshwater after 2 or 3 years at sea it is also referred to as a salmon trout, several other fish in the Salmonid family are called trout and some are anadromous like salmon whereas others are resident in freshwater only.

There are around 340 separate populations in the British Isles and they are often described as ‘remnants of the Ice Age’ perhaps because of their association with the Arctic and the fact that they [along with other species including Trout and Greyling] populated our waters soon after the glaciers retreated around 12.000 years ago. They arrived as sea run Char, and then subsequently lost their sea migratory tendencies: becoming freshwater resident populations, occupying mainly the deep lakes of Scotland and the Lake District.
