 The feluccas were at first used to gather shrimp in the SF bay, but when this fishery was abandoned to the Chinese, they gillnetted for local bay fish, trolled for ocean fish, and pulled up the famous Dungeness crabs.During this period, they made up about two-thirds of the 85 or so fishing boats that served the city.Later, as the fleet grew, about 50 boats serviced just the crab fisheries.
