wbuffet, I'll be 100% honest here.. I'm the wrong guy to give any advice about a trout pond. I have very little experience with trout, even though I understand what you are looking for I just have no knowledge of how the GSH may affect the cycle of any trout species.
The one thing that comes to mind to me about trout is their ability to subsist on small larva, insects and small aquatics in general.
Maybe ewest, Cody or someone else here will have some input on this. I just don't feel comfortable suggesting adding GSH with no knowledge of this combination.
