Salt water & Vinagar will do the trick !! Wil also work on ANY strong tasting fish , Just a 1/2 a cup a so should do it ... doesnt matter what kind, cheaper the better it works lmao
ALSO , In the summer time , its best to have Iced Water and make sure it STAYS ICED water the Whole trip & place the fish in it As soon as you Cath em to make em better, No Live wells tjhis time of year , Ice em down as soon as you catch em !!
