That sort of senseless waste makes me extremely angry. So please, if in doubt, release a fish rather than kill it for no reason. On of the best days on the water can be enjoyed by taking the family for a picnic to a secluded beach or island. Do check your local fisheries regulations on crab traps as they differ greatly from state to state. Even the most basic of anglers should understand that the fresher the bait used, the better the results.
Fresh bait is also local bait and more likely to be what the resident fish are feeding on.
A simple yabby pump is an item which lasts a lifetime with a minimum of maintenance and provides hours of fun for all the family. Just take care to disturb the habitat as little as possible and only take what you need. Above all, keeping it simple is the main ingredients of fun. As a specialist I can relate to the fact that I often went overboard with my own children, expecting too much from them and not letting them enjoy the simple things the sport had to offer. Trailerboat fishing is a sport which really needs to be shared.
