Some of the depots will have a supply of the waterproof forms to be filled in (unless they have run out). The forms have attached string so they can be tied through the jaw. If I don't have them I usually just write on scrap paper in pencil, chuck them in the freezer in a bag, and tranfer the info when I get some forms. You need location local name, length, weight, species, stat area, hatchery/wild, date, and your contact info
