I'm going to watch the video, and get an electric knife.
Caught and cleaned 13 yesterday. I'm not good at filleting, that's for sure. I think I used a slightly different technique for each fish. Most were 8 to 9". It just doesn't seem like there are 1200 in there.
One other question. I was trying to determine sex of the YP, are the eggs like a white fat? I have cleaned a lot of LMB with yellow eggs, I was looking for eggs like those.

9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
