I'm pretty convinced virtually all the BG are gone. It's been about 90 degrees here and lots of pond activity. Tadpoles everywhere, frogs...even little fish (can't tell what they are).
The BG did spawn last summer even though I only put them in in April. There were spawn nests all around the pond. So far this year, nothing. I've been tossing feed in from the dock where I fed them last year and haven't seen one.
The only explanation (given how healthy the pond is) I can think of is the otter. But taking out all 500 BG...plus the ones they spawned? Don't seem possible to me.
Anyway, I bought 50 LMB and introduced them to the pond today. I'm thinking I should get some more BG next month and start over with that.
