Species above are divided into the general Trout/Salmon/Char groups based on their habbits. Clearly, the taimen is not a member of the char family, lenoks are hardly trout while sea trout and steelhead have no genetic differences with brown and rainbow trout respectively.

In European rivers where conditions allow it, some brown trout migrate to the sea. They are known to re-enter the rivers without any particular pattern or reason for that but eventually they will spawn in fresh water in small streams sometimes only a couple of feet across. It is a wide spread belief that sea trout can only be lured under low light conditions, particularly during the night. Nights with a full moon are considered the best fishing time.
In some of the typical sea trout rivers of Scotland, like the Esk and Dee, fish are usually in the 2-3lb range and smaller, but occasionally bigger ones are caught. The rivers of the Great Lakes and Argentina, on the other hand produce runs of very big trout with some fish in the 15-20Lb range.
Sea trout can also be targeted on the beach in countries like the UK, Denmark, Germany, Sweden and Norway. This can be done by spin casting heavier lures (kastmasters, pilkers etc) or using flies and double handed rods in places with good structure where trout are known to feed.
