Kenny - this sucks. Let's talk this week, you sure have some weird stuff going on down there with your crayfish. I've never seen or heard of anything like this before.

TJ, My #1 biologist that I trust that has taught me a big portion of what I know now to be true says the same as you.. WTH is up with your craws, Kenny???? He says he's seen this once or twice before in winter on known poor water quality BOW.
He also told me when I stocked just barely 2lbs of craws when I did-that it was a mistake. He was ABSOLUTELY correct.
He suggested waiting until spring of year 2.. That's why I'm recommending to anybody asking for advice about craws NOT to do it at first.
Thought that comes to mind is "what do you suppose 425lbs of craws need of what weight to grow like they did???"
I know I had Sago coming good, APW, Pickerel, Arrow head. It ALL disappeared, just started getting some Arrowhead showing up this summer, still no Sago.
Kenny has a long ways to go to fix his screwups.
