I know this sounds quite labor intensive, but I mix a 5gal bucket every time I fish.. I soak every fish I catch unless it appears perfect, then I just do a dip n go. It may not get rid of them but I'm stopping the cycle of as many as I can.
I do this with fall net samples too..after measure-weigh they go into a 200gal tank mixed this way and I do 5-6 fish at a time. Some fish get it twice in 7 days because I know I get some recatch but 700+ fish dunked in 7 days without any loss makes me feel better I guess.
