Night feeding for Trout & CNBG?

I stock rainbow trout, RBT, in early December. They last until mid to late May, when temps get too high even at depth for them to tolerate.

Last week water temps were in the 50s and the RBT were feeding vigorously on food pellets. Last couple of days temps have warmed, water in upper 60s low 70s during the evening. LMB, HSB, and CNBG going crazy on feed, but not a trout to be seen. Up until today, feeding times were only 1pm and 6pm. Now I've added 2am, mostly due to food depredations by Canada geese.

Query One: Will trout be more willing to feed when water is cooler at 2am? Like most smaller waters, my surface temps can vary 10F from night to day, depending.

Query Two: How does night feeding affect CNBG & LMB? Are some of them willing to eat feed after dark that won't during the day? Or is it pretty much the same fish, night or day, that chow down?

Cant help with question 1.

On question 2 you have to account for predation. LMB have better night/low light vision ability (more than just sight obviously) than BG. BG subject to predation will be more wary of feeding. BG of the size beyond predation will eat at night/low light.

Thanks, Eric. Not a bad thing to selectively feed my biggest CNBG at night, I guess. Hope my RBT get some extra benefit, too. Would love to see a study of the impact of night feeding, birds are getting really bad but it's hard to find sinking fish food providers of quality.

Let everyone know what happens - a good learning event !

Feeding the big CNBG at night and the rest of the pack during the day might be a good whole population method.

Bob L. seemed to think that mostly the same fish which eat daytime pellets will eat nighttime. Of course, that might not apply to trout which are sensitive to daytime water temps. Anyway, I'm gonna shift even more feeding to night. If I had sinking feed, there would be less Canada goose issue, but this is best I can do for now.
