I just finished reading about eliminating bullhead from ponds. I was wondering if the same techniques would work for FHCs? (Flat head Catfish)

At what water temperature do FHC spawn? The same as LMB?

They used garbage cans with 6" holes during the spawn to remove the fish and eggs. Would a FHC hold up in one during the year just because it is a secure place to hide when they are not hunting for food? Do you think it might also work for Bowfin?

It seems like a new idea that is worth a try. I have had lines out all summer & had some success removing FHC & Bowfin. Now that the water has cooled so has my good luck removing them.
