Of course mate,

what about the trout that naturally spawn ? Their fry just dont disappear mate, i think its something like a 1000/1 survival
so for every thousand fry, one survives,


seen lots of small fry in the loughs here washed down with the floods ,

they looked to be feeding and have smiles on their faces ,

Hi OD,

Yes you will have recruitment into the shallows in lakes but the mortalities are far higher that fry stocked out in rivers. I would suggest that you identify small feeder streams if available wih the right habitat, riffle sections, and small pools for holdingfor stocking out. The one thing you need to identify before doing this is that you are not stocking trout into areas where there is natural recruitment and in turn displacing the wild population and creating too much competition for food. It will have a negative impact.

One thing that was said to me the first day i ever took part in stocking was this,
a fingerling doesnt have a single friend in the world, he s on the menu for everything, lol
poor sod, but a percentage do survive, its a survival battle all their life

It's best to stock them into the feeder streams OD ,then they can acclimatise better and will have a better survival rate than in the lough .Have you fry ready to be released already ?

Feel free to correct me if I am wrong but do you not need the o.k from Sepa or whomever the governing body is to introduce fry into a stream or river system?JB

The fry in the OTFA hatchery here on Orkney have only started to hatch out in the last couple of days. The hatchery etc has to be registered with the relevant Scottish Office Dept, the exact name of which escapes me. The fry will stay in the hatchery until their sac is just about gone, they are then planted out in burns and lochs throughout the North Isles. We estimate about 70 to 80 thousand fry in total,
Cheers Ken

Does it also depend if the fry are derived from that lakes stock?

We seek for slumbering trout
And whispering in their ears
Give them unquiet dreams;
Leaning softly out
From ferns that drop their tears
Over the young streams.
Come away, O human child!
To the waters and the wild
With a faery, hand in hand,
For the world's more full of weeping than you can understand.
