Fish, squid or bacon?
Fish pieces can be convenient if you already have suitable bait. Squid is another option to secure inside a bag. Bacon is often suggested, but it is not essential to buy it specially for crabbing. Choose for availability, clean handling and the ability to secure it, rather than treating any one food as a proven winner.
Secure it before approaching the edge
Prepare the bait on land. Put a small amount inside the hook-free bag and check its closure before lowering the line. Keep unused bait contained and packaging away from the shore. An adult should manage the line and supervise children closely near water.
When should you check the bait?
Bring the line back under control if the bag is empty, damaged or not holding the bait. There is no fixed waiting interval that works everywhere. More bait does not solve an unsuitable location or an unsecured bag, and loose food should not be thrown into the water to encourage catches.
If nothing is happening
Check the bag and line first. Conditions and the presence of crabs matter too. Do not lean out, climb barriers or search for deeper water from an unsafe edge. It is fine to finish without a catch and choose a different shore activity.
Clean up and return catches carefully
Keep bait and its utensils separate from food you will eat, and wash hands after handling it. Do not deliberately use spoiled food. Keep any observation brief and uncrowded, minimise handling and return crabs gently where they were found. Remove leftover bait and every piece of line.
