crabber

noun

1. A person who catches crabs.

   “Many shrimpers complain that the crabbers place their traps too close together and that they can't go between the traps without snagging their nets.”

2. A boat used for catching crabs.

   “In the bright haze of morning they came into Hort Harbor, where a hundred craft were moored or setting forth: fishermen's boats, crabbers, trawlers, trading-ships, two galleys of twenty oars […]”

   “It is standard practice for search and rescue authorities to ask other vessels in the area to assist. Usually, this is done. The weather on the night of 31 December was too atrocious, and when at 11pm the Coast Guard asked the crabber Ruff & Reddy to head to the scene, its skipper refused, as a skipper has a right to do if he believes conditions to be too treacherous.”

3. A person who finds fault or criticizes.

   “There were one or two crabbers, of course—people who wanted his job—but no one paid any attention to the likes of them.”
