The shiners are just like the ones sold in most bait shops around here, porbably because they spawn a lot.

I am only using observation as a tool for determining whether or not my BG have spawned. I check the pond daily and scoop up any fry I find with a net and have found only shiner fry. Also when I feed the fish daily I never see any small BG. I never see a FH either, coincidentally, and I added 10# of FH, and only 5# of shiners.

A neighbor with a much more mature pond than mine has had two BG spawns so far, so I know its not the weather anymore.
