Bill,
I didn't check for fat content. I'm not really sure how to do that on a fish. We've got a big rain coming in today, and after it clears out I'll go get a fish or two and dissect it if you'll tell me what to look for. I've been reading up about fertilizer, and I'm thinking about broadcasting 500 lbs of 19-19-19 into the pond. Do you think that will be enough for a 2 acre pond? Thanks again for all the help. My little "die-off" has got me paying closer attention to what is going on. I'm just going to have to start removing fish from the pond and get the population down to a proper balance. Thanks.
