Salmo trutta morpha trutta
The sea trout (salmo trutta morpha trutta)and the brown trout (salmo trutta morpha fario) are fish of the same speices

Unlike the salmon not all brown trout bother to migrate, the majority live out their whole life cycle in fresh water. Only in the last century was it realised that the Brown Trout and the Sea Trout were the same species. Just why some brownies become sea trout is unclear. Certainly the rivers of the west coast of Scotland produce more sea trout. This may be because they are generally poorer in terms of nutrient (spate rivers). So the trout may be looking for more food. Rivers which produce a lot of juveniles may also stimulate a return to the sea since adult trout are territorial. Poorer specimens are forced ever more downstream until they reach the sea and richer feeding. Their brothers and sisters must get quite a shock when these fish return as monsters!

The eggs of Sea Trout are laid high in rivers and streams in areas known as redds. From here their development begins and eventually the small fish hatch. At this stage, known as Alevin they are sustained by a yolk sack, which provides nourishment to give them a good start. As they grow the Yolk sack is used and disappears, the young fish becoming Parr, dependant on their resources to feed.

Sea trout, brown trout and even Salmon Alevin inevitably share the same rivers and nurseries. A juvenile sea trout parr is very similar in appearance to the juvenile brown trout; markings are similar and both may share the same stretch of nursery. As a sea trout grows its genetics change and anatomically it develops organs that a brown trout lacks. As parr become smolt, herling or peel, it develops salt secreting glands in its gills and changes colour from its brown trout characteristics, eventually resembling a salmon more than a trout

The Sea Trout is termed an anadromous fish; a fish which breeds and spends its early life in freshwater, before migrating to the sea.. It then returns as an adult to freshwater to breed and continue the species. So to put it simply, the Sea Trout is a Brown Trout (Salmo trutta) that heads out to the sea. There are many theories regarding this migration, the most probable one being, the lack of food within the river system makes such migration necessary for survival. Evolution has taught the Sea Trout that the abundance of food in the sea gives them an evolutionary advantage.
