It shouldn't be a big problem to artificially fertilize bluegill eggs. The
fertilized eggs are heavier than water and adhesive, so you want to provide
for an even settling out of the eggs. If you check out a male's nest you can
pick up small rocks from the nest and find the rocks covered with eggs. They
take 2-3 days to hatch, and the larvae take 2-3 days to grow from "wigglers"
to true gill-breathing fish that become free-swimming. At this stage, ~7 mm
long, they should be able to take fairly large food like brine shrimp (or
whatever...). And then you have many, many bluegills.
