Now how did I know what you were going to ask?
Should I be starting a new thread on seatrout fishing? Or will you do it?
After about 2 years spent in a river, young seatrout, at approximately 15cm - 20 cm in length, will start to turn silver (usually around April or May time). These silver fish are what we call 'smolts' and are ready to migrate to sea where they feed and grow rapidly to about 0.5 kilogram plus and return to the river from mid July onwards.
These seatrout returning to the river wil eventually spawn in late autumn or early winter and then migrate back to the sea during the late winter period. They will then return to the river year after year, growing bigger on each vist to the sea.
The bigger seatrout may return to the river anytime from about April onwards and, depending on age, weigh anything from about 1 kilo up to the very large fish of 7 or 8 kilo's - ( typically 1.5 to 2.0 kilo's).
Genetically these seatrout are identical to the resident brown trout Salmo truta
I use a fly rod 3 metre long with a #8 line for seatrout, the leader used will be about the same length as the fly rod and 2 or 3 flies are used. (Yes - I know many of you guys think this is poaching; but it is accepted in the UK).
The lines used may be a floating one or any of the different sinking densities. Line density selection is generally based on river levels; low river level = floating line; high river level = fast sinking line.
Flies sizes will vary from a size 10 up to size 4 (sometimes flies are tied as doubles, trebles, tube-flies or tandem mounts).
Anglers wait on the bank until it becomes dark and then enter the water to begin fishing (no light should be allowed to flash on the water). Fish can be caught from night fall through to dawn.
Flies are nearly always fished through the pools in the traditional down and across wet fly style.
But sometimes, as an alternative to the traditional wet fly style, surface lure is used on a floating line to create wake (wave) when it is retrieved; other times when fishing very slow sections of a pool a fast sinking line will be used with a buoyant fly.
I will photograph and post some of the flies used for fishing after dark.
