This stream you can jump across for the most part. Surely these are migratory river fish.
Having been reading on the subject of migratory browns they move more in the fall/winter than in the summer/spring.
I can't put my finger on why they are still here. I mean assuming one of these fish snapped me off in the summer, then they came for thermal refuge and to breed in the fall.
When are they using the river? Surely for longer than just spring.
It would be interesting to see these fish tagged and studied.
Oh and I caught mine on a 6" long articulated deer hair sculpin.
were they lightly spotted ?
lake run browns run in the spring and fall - in spring they are chasing smelt, in fall they are spawning.
sea run browns in the UK, Ireland and Europe run from April to October and spawn in November - January. this is temperature and flow dependent.
i think it is possible that they could of run up in early summer, but unlikely due to the thermal issues of that stream. i think its more likely something else broke you off and its a coincidence.
The fish that are there now is a different matter - they are there to spawn or feed and i would think will be there until March / April.
the size of fish to creek ratio does not surprise me in the slightest - many small streams in Wales and on the South Coast of England produce fish in the 13-16lb class, The Arun, Adur, Ouse etc are famous for them.
Whilst the timing suggests that these big browns are there to spawn, the lack of reports of YoY browns in that stream (or larger fish), suggests to me that they can't be spawning there.
I would suggest notifying the PFBC and getting them to a) designate the river as C&R only and b) surveying the river in April or May when there should be juvi trout around.
My hunch is that these fish are overwintering there after spawning due to the food available and move out when the days lengthen to deeper water awaiting the shad run, and before the thermal issues occur.
My hunch does depend on there being somewhere on the Susky for them to spawn though - are there shallow gravelly areas ?
and FWIW, i don't think this is the only stream where this migration is happening - i think its likely in Deer Creek MD, and one other.
I plan to check out both streams in March to test my theory, as my only surprise was this wasn't happening - which i was told was due to the dams - as i posted before - Loch leven browns are migrational wherevr they are planted.
Cheers
Mark.
