From above

A big fish smashes through the fry shoal, scattering it in a ring of quick splashes, then circles back slowly to mop up the stunned ones — the take comes on the pause, not the charge.

From the side

Stage one: the charge — fry shower and scatter. Stage two, seconds later: the trout returns for the stunned ones. Your fly is a cripple — strip, then STOP.

On the lough

The fry smash

Fry scattering like flung gravel means a big trout is hunting — and it will come back for the stunned ones. That's your fly.

You'll see

Small fish showering out of the water in a spray, an explosive boil behind them, gulls or terns dropping onto the same spot. Late summer and autumn, shallow weedy margins and bays.

What it means

A trout — often the best fish in the bay — charging a fry shoal. The attack is two-stage: it smashes through to stun, then turns back to mop up the injured. The fish you can catch is the one coming back for cripples, not the one mid-charge.

Log it: this is what the session’s fish activitychip means by “chasing fry” — telling the plan what you’re seeing sharpens what it hands back.

How to fish it

Hunt with your eyes first
Find showering fry or working birds before you cast a line. Weedy shallows, harbour mouths, warm bays — approach low, quiet and sparing with casts; these are spooky fish in clear water. Out on the open lough the packs MOVE — terns and gulls follow the hunting trout, and the play is the opposite: keep your eyes peeled and get to the activity quickly, ahead of the shoal.
Put the fly where the smash was
Cast past the boil and bring the fly through it — or drop the floating fry into it and leave it lying on its side, dead.
Strip — then STOP
One or two sharp strips to say 'injured fish', then a long pause. The pause is the tactic: the returning trout is picking up cripples, and a fly that stops and lies stunned is exactly that. Most takes come on the stop.
Twitch and wait again
Nothing? A small twitch, another pause. Cast sparingly — every thirty seconds is plenty. Resting the swim beats flogging it.

When to strike

Wait — say LoughLogic twice

Nothing on the smash — it's the herding charge, not the eat. Fish the pause and strike the draw: when the line slides away or goes heavy, pull into it low and firm.

Easily misread

Casting at the smash itself

You hit every eruption instantly, strip fast through it, and touch nothing.

Instead: The eruption is stage one; the eating is stage two, seconds later, slower and deeper. Fish the aftermath: stunned-fry pause, not fleeing-fry sprint.

"Fish rising everywhere!"

Showering FRY misread as rising trout — a dry fly goes over them.

Instead: Watch the direction and size: a spray of tiny fish moving AWAY from a boil is prey escaping, not trout rising. The trout is the boil.

When you'll see it

Late August through autumn, as trout bulk up before winter
Shallow, clear, weedy margins — weedbeds hold the fry shoals
Early morning and evening light; midday only under cloud
