Bait canister for the crab pot
A perforated canister with a bayonet lid that keeps the bait in the pot rather than in the crab after two hours.
The problem
A mesh bait bag lasts one trip. The crabs tear it open from below, sea lice take the rest, and you end up tying a new bag in the dark with cold fingers.
The fix
The holes are 8 mm — enough for the scent to get out, too small for a claw to get in. The lid is a bayonet, a quarter turn with 0.25 mm clearance, so it can be worked with gloves on and will not open by itself when the pot is dragged over the gunwale. PETG is chosen because it sinks. The same canister in PP would float and sit there pulling at the pot.
It ties on with a loop of the pot's own line rather than metal, so there is nothing to corrode into place. It must not sit where it covers the escape openings or changes how the pot behaves. The dimensions for escape openings, rot cord and gear marking are set out in the regulations, and they have to be checked before anything is fitted. After a season a canister like this smells appalling whatever it is made of. It is designed to be scrubbed, not to come up looking new.
I do not assess whether your pot is legally rigged. The requirements for escape openings, rot cord and marking are in the regulations, and responsibility for compliance rests with whoever sets the gear.
