I could tell from the bank last summer that I had 1000s of fish, just don't know how many 1000s. I just have BG and LMB and they reproduce as if they know their kids will be getting medicaid and food stamps. I said be fruitful and multiply and it was so. We shall see soon enough when things warm up, but even if I lost 1500 fish, I think I'll still be ok. Might as well be positive. I know of a pond the same size as mine where the owner took out over 3000 floaters after a fish kill and he was catching fish that summer.
