fly fishing techniques, but only when the rivers are running clear. Sea trout are very easily "spooked" by bankside disturbance and during daylight hours tend to be tucked up under the banks and submerged tree roots, and therefore very hard to catch. At night they feel more confident to come out into the main river flow and can often be seen "running" (migrating upstream) in the shallow runs during the months of May to November. When the rivers are flowing coloured in a spate following heavy rain, it is possible to catch sea trout during the day with artificial lures or spinners. The fishing season for sea trout in the Clwyd catchment is from March 20 to October 17 inclusive. Many fly fishermen would agree that night fishing for sea trout can be one of the most exciting forms of the sport as the fish can grow to more than 10 lbs (5 kg) in weight. The Rhyl and St Asaph Angling Association controls 20 miles of river fishing on the rivers Clwyd, Elwy and Aled.

In most estuaries angling is completely prohibited in a protected area of 200 metres around the river mouth during this time. In the coastal waters of Mecklenburg-Vorpommern, there is a general prohibition on fishing for sea trout from 15 September to 14 December. This applies both to fishermen and anglers.

The surviving young of sea trout will generally migrate back to the sea, to feed in estuaries and coastal waters. However it is also known that the adult brown trout, which may have spent some years entirely in a river, can, for whatever reason, decide to migrate to sea, to return next year as a much

In North Wales the rivers Clwyd, Elwy and (to a lesser extent) Aled have runs of migratory trout, otherwise known as sea trout or, locally, sewin. Sewin generally refers to smaller sea trout up to around 30 – 40 cm in length. Fishing (angling) for sea trout is usually carried out at night using

Anadromous brown trout are a silvery color with faint black spots. However, once they return to freshwater, they quickly take on the normal coloration of resident brown trout in preparation for spawning. Sea trout kelts (post spawn) return to their silvery stage as they migrate back to saltwater.

Fish that are ready for spawning are usually lean and have to eat a lot of food in order to increase their energy levels as quickly as possible. After completion of the spawning process, the fish return to the sea. The mass mortality after spawning that is common in some species of salmon is not

Adult brown trout are between 35 and 60 cm (14 and 24 in) long, and can weigh from 0.5 to 2.4 kg (1.1 to 5.3 lb). Breeding males will develop a hook-like, upward-facing protrusion on the lower jaw called a
