Donald, you will definitely see people around there are much more than crabs. Um, also, I just like to remind you that people without licence are not allowed even to touch the fishing/crabing gears. But, as long as there are not policmen, you will be safe
Crabs like rotten food, like samlon head, chicken legs.(Sometime, I feel the food I treat them is better than I treat myself :lol: ) The best way is to expose the bite under sun for some days to let it rot.
