I pour of all the excess water off the left over minnows, pour in enough rubbing alcohol to barely cover them and put them in the fridge for a few hours or even overnite. Pour off excess alcohol and put them in small baggies and into the freezer. Take out how ever many vags I need next time out. I tried straight frizen and salted but the " drunk" minnows seem to stay firmer longer. Just started experimenting with this, this year, so ...so far the drunk minnows are best!! My last two trips out, live minnows were not availiable so frozen minnows put perch in my freezer!! Better than sittin on the couch......
