My definition of fresh stocked is: anytime they are stocked in low water conditions until the water gets back to normal. If stocked in faster heavier flow, they take care of themselves much quicker.
Current flows mimic nursery/raceway conditions, I think. For 19 months these fall stocked trout were looking at each others anal pores in a very controlled condition. The only time they fall out of "lock step" (bunched up and content) is when someone walks overhead or the feed bag goes on. Then it is chaos.
Until they have to separate to find food or the water gets high and they need to find lies, they have no reason to change their behavior.
What you are seeing in my opinion is:
1. The water is very slow at this time and they are bunching back up.
2. You spooked them, which makes them scatter but remain focused on each other because the water conditions don't have them preoccupioed with remaining in a lie.
3. They are scared to death of you...you have been beaning them on the head for a month...pulling them around and squeezing them while you take videos under water. You gotta be like the scariest person on earth to these trout.
Maybe try a costume next time.... :lol:
Seriously, # 3 was a light hearted joke.
Did they look anything like this...these are fish we stocked on a monday and on the next Monday they were in this slow area below a bridge tailout. They are not there anymore....and when stocked, only about 6-7 were put within 200 yards of this area. Somehow in that week they found each other and exhibited strange grouping behavior...probably a family reunion of sorts. But now they have moved on. I should add that these fish were all 13"-16" long brown trout. I had to adjust the contreast on the pics to be more clear. Hence the quality. Anyway, take a look at the pics.
