Hey I was wondering what these bumps on this bass are. They were on several others we caught that day too. They seemed to move too. Don't know if they are some kind of flea or something. Thanks.

Maybe they are some kind parasite that lives under the skin.

That is nasty, never seen that before.  I would definitely report to the DNR. 

i have no idea. but im not a parasite expert. but i have done a tiny bit of homework about the fish louse. and i dont think thats it!?

here. i butchered this pic from someone else. but i do believe this is a fish louse on this pike. its an external bug. not under the skin...

I've never seen anything like that before.  Yuck!
