HI,
Definately good advice from the lads..this fish is stale and less likely to take so forget him ! Undoubtedly he is active and still feeding on occasion.Higher water temperatures will make sea trout and salmon 'turn stale' much quicker than in average temperatures.This makes them lethargic and less likely to chase a bait.
Now the other point to consider is ..the pool the fish is in -is it a holding or a resting pool ?
Holding pools-sea trout like salmon will take up residence often for long periods lying in one particular pool before moving on..Some fish simply drop into a good safe lye with an adequate flow of oxygen and in a position whereby as little energy as possible is expended in pursuit of food items.Moving further upstream during the next spate.
