I was at my pond yesterday, and saw several hundred small juveniles around some sunken pallets(or frye, they were maybe 1/2" to 3/4" long).

I couldn't tell what they were exactly, but they had the shape of a Bluegill or Panfish.

I am fairly certain they were Black Crappie babies. My water temp was 64 degrees, and my Bluegill have not formed beds yet. Some LMB look like they may be creating beds. I did not see any Yellow Perch egg masses, but I could have missed it as I haven't been up to the pond much over the last 5 weeks.

Excerpt from Robert Crais' "The Monkey's Raincoat:"
"She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
