Can't say that I have. I think the lice like the same water as the stripers. I see lice from April through October. The striper I am catching during that time are not all migrating. In fact, I believe those fish I catch during the months of June, July and August are in fact summer residents just like me. They just inhabit the same temerate waters and that is why the fish carry them
Point of interest.... the lice love lobster too. Particularly injured ones. They do not migrate like the stripers. Not anywhere as far anyway.
Again, I think they are just like ticks and dogs. Go where the ticks are and you'll pick them up.
