I posted these questions awhile back and I'm still working on answers....

Questions:

1) Do PS stay more active as the water cools than the BG do; maybe making the PS perhaps more elusive with a better chance at recruitment?

2) I would think the SMB and WE will also target small SMB and YP. Can BG and PS together provide enough additional forage for the predators I have with good management of predator numbers?

3) Should I stock more adult BG?

4) Should I start harvesting some of the larger YP?

Any suggestions or comments would be appreciated! smile



I've been doing some research and I THINK I might have an answer to question 1.

While both BG and PS are considered "warm water" species, their temperature tolerance ranges overlap. BG have a greater tolerance to warmer waters but PS have a greater tolerance to cooler waters. This makes me consider that small PS might be more active in cooler waters than small BG; making PS less susceptible to predation by cool water predators in early spring and late fall than small BG.

Anybody have any thoughts, experience or comments they can share?
