Correct me if I'm mistaken, but seem to recall warnings that overpopulation of golden shiners caused them to excrete chemicals that suppressed spawning. So would this also suppress spawning of other fish?
I don't know that I've seen those warnings, but perhaps. I have certainly seen golden shiners raiding spawning nests of bass, so there's surely a reduction of spawn for LMB there.
I also have not heard about the females becoming sterile, but I've never sought out any related information.
To be clear, I've amped this pond with Golden Shiners, repeatedly. But I haven't for a few years and am surprised at the large amount of GSH in the pond along with predator fish that I can see feeding. I do agree with all the input that I may not truly know what my predator population is.
