Cecil, couple of things.
First, is there a link or reference to pellets-in-pantyhose presentation that the browns hit on? That sounds intriguing. I saw some good references elsewhere in PB to pellet flies, which I'm also going to try.
Next, with regard to carrying capacity. My pond is a bit bigger than those you referenced - 130 x 60 ft - and fed by underground springs and above ground seepage - plus a 1/2 hp submersible pump of river water (not O2-saturated). Plus the two diffusers - one on each end of pond. Do you think this setup somewhat matches carrying capacity of the O2-saturated 41 gpms? (I'll have to measure the flow of the pump, but I bet it matches or exceeds 41 gpms)
Last, wrt newly introduced trout I've read that trout will eat anything up to half their size... But properly fed I'm guessing I could put in some more 6-8 inchers in the next couple of weeks with little loss. Do you stock annually each pond, or do you grow out and clean out before stocking again?
Lastly last, from your earlier comments, I should guess that the slower-growing and more timid brookies I first put in are in high stress and likely just not doing well in the face of more aggressive rainbows, and even the browns introduced later. Do you ever mix trout species in a single pond? (I think brookies are gorgeous...)
Huge thanks for your comments. This stuff is excellent.
