  • Sea trout in the British Isles, which is anadromous in spawning behavior, is also known according to region as sewin in Wales, finnock (Scotland), peal (West Country), mort (North West England) and white trout (Ireland). It is the entry of the fry into the sea that governs the growth and subsequent spawning of this fish, which is genetically identical with brown trout.
