Thanks bbjr, you're not the only one with questions about northern climate. I'll try to look into this soon.

I'm getting more confident that the eggs I collected are BSF eggs. The little BSF larvae in the hatchery seem to be doing alright with the Gamefish Chow, but I wonder if Purina might consider marketing Maggot Chow. \:D

Here's a photo of the hatchery this morning.
