Lobster trap rope, flag markers, gaffs, bait bags, buoys.
The bait bags that come on a spool like the green ones above arrive in one long tube of mesh. The lobstermen cut the desired length, bunch up an end and then clamp it to make a mesh-like purse. Then they stuff the herring or pogies in the bags and set them in the lobster traps.
The orange twine pre-made bait bags shown above are much more heavy duty than the green plastic bait bags but are also way more expensive. In the winter when the seals show up many lobstermen will switch over to the orange heavy duty bait bags because the seals rip the green ones right out of the traps to get the bait inside. The orange bait bags hold up much better against the PITA seals.
