When looking for fry feeders there are a few main things i look for, drop offs or ledges and weed, If you get the two combined, the stickleback will be present and the trout will not be too far behind.
All through September and into October the
trout will hunt the sticklebacks, but this year the trout in my local lakes went on the fry mid July. Fish would pitch several times in the one spot, crashing through the fry and stunning them. These fish would then slowly swim around taking stunned stickleback
as they went.
On windy days the trout would herd the stickleback onto the top of the shelves or onto the top of isolated weed beds in deep water where they would commence their assault. But on calmer days the trout would force the prey into balls anywhere
out in the lake and then attack them. Just like Tuna and Marlin do on the wild life programs that we all look at.
I prefer fishing the former as you can repeat drifts you know are right as you can line the structure up to drift
onto. When the trout are bashing fry in deep water, once they attack a shoal they will disperse the rest of the shoal and after feeding on the stunned fish they will have to ball the sticklebacks up again. This could take place a 100 yards or more from the
previous attack. You always have to watch for trout pitching out of the water and then drive the boat towards the commotion, hopefully reaching them befores the onslaught ends.
If the fish are actively feeding i will set up a cast with two popper
fry on a floating line as described in the photo above. Casting towards the feeding fish i let the flys rest on the water and then pop them a few times with a couple of quick pulls on the floating line. The flies causes quite a disturbance on the water and
will get any trout in the vicinity to investigate the easy meal. If a fish does not investigate after 20 seconds i will repaet the process , but i will only do that on windy days. If it is calm i will cast out and pop the flies twice and leave them sit as
the fish are much slower gathering up the fry in calm conditions.
