How do you know, after you reach the bottom of the drink, what kind a fish is and if it's edible and if it's legal, and how many you can have? Do you guys keep a small book or chart or what not on the boat? I saw some under water cards at the dives shop, but they were for species and state records, not bag limits.... any answers? I am thinking of printing out a common species guide on like small cards with bag limits and whether they kill you to eat them (you know little things...lol) and laminating them for when I start spearfishing.
