Abstract
This paper presents results of an exploratory survey of deep benthic fish and crustacean resources in Hawaii. The purposes were to determine if any unexploited species are present in commercial quantities, to test methods and gear for these and some presently exploited species, and to provide general information on the depth distribution and biology of deep benthic fishes and crustacea. The survey was conducted using traps and gill nets set on the bottom. The equipment required, a fathometer with the proper depth range and a heavy-duty line-hauler for retrieving gear, could be mounted on most local fishing vessels. Also, it was felt that sampling with set devices would be a useful complement to recent trawling surveys conducted by the Honolulu Laboratory of the National Marine Fisheries Service. Three types of fishing were considered: trap fishing for unexploited shrimps below 80 fathoms (ca. 150 m), trap fishing for presently exploited crabs and lobster between 30 and 100 fathoms (ca. 50 and 185m), and gill netting for fishes presently exploited by hook-and-line between 60 and 200 fathoms (ca. 110 and 365 m). After a general description of gear and procedures, each of these areas will be considered separately.
