My wife and I are moving to some land in wisconsin which has an artesian spring fed trout pond, maybe 1/3 acre, up to 10 ft deep. There are only a couple of rainbows left from a stocking 5 years ago. Like sadworld, I'm also interested in stocking a breeding population of trout, preferable rainbows although from what i've been hearing, that's near to impossible. Paul from Rushing Waters trout farm in Palmyra swung out and checked out the pond and said it would be excellent for raising trout, but said that very few people attempt to breed them and couldn't offer much info. I'd like to try it for the sense of sustainability (in the same way that I plant a lot of perennials but no annuals), but also because I was biology and genetics major and just want to do it as a hobby project. Does anyone know what the major problems with breeding tend to be? Any experience or tips? Also, are there any good books/texts/resources out there to refer to? I've been looking but haven't found much yet.
