Oak has tannins which is lethal. I much prefer cedar which lasts 4 years. When my pond was built there were some big oak brush piles that I had pushed into the bowl. It rained, got about half full and I stocked fatheads and bluegills. The water turned black(tannins) and everything died. I stocked again with the same result. Then I bought a pump and spent a long time pumping. When everything dried out, I burnt the wood and pushed the ashes and junk out. When we got some good rains, I bought minnows to check the water quality. They did ok so I went ahead and stocked.
I guess a small amount would be ok but I personally will never again take that chance.
It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP
