^ Number of participants estimates are based on state and federal fisheries permit data. The estimated number of participants is expressed in terms of the number of active participants in the fishery, when possible. If this information is not available, the estimated number of vessels or persons licensed for a particular fishery is provided. If no recent information is available on the number of participants, then the number from the most recent LOF is used. NOAA Fisheries acknowledges that, in some cases, these estimations may be inflating actual effort.
*Observer coverage levels include the latest information reported in the most current final Stock Assessment Report (SAR).
1 Indicates the stock or species is driving the classification of the fishery.
No mortalities or serious injuries of marine mammal have been documented in this fishery in recent years. Hawaiian monk seals were previously included in the list of species injured or killed in this fishery, but were removed from the list on the 2015 LOF. There are no reports of Hawaiian monk seal entanglements involving this gear since 1986, when one seal died in a trap in the Northwestern Hawaiian Islands.
From 2008-2012, four humpback whales were reported as entangled in Hawaii trap/pot gear (Bradford and Lyman, 2015). However, none of these have been attributed to the Hawaii lobster trap fishery.
Based on an evaluation of information available at this time, there is a remote likelihood of marine mammal serious injuries or mortalities in this fishery.
Fishing can occur in both state and federal waters. Lobster traps are generally set in shallower waters (< 100 ft).
Trap fishing includes fishing with any of various fishing devices made into the shape of a box, container, or enclosure, with one or more openings that allow marine life to get inside but keep them from leaving.
The fishery is monitored and managed by the Hawaii Department of Land and Natural Resources, Division of Aquatic Resources (DAR), NOAA Fisheries, and the Western Pacific Fishery Management Council, as appropriate. In general, fisheries are managed for the species harvested rather than by gear, but in some cases there are specific management measures for particular gear types or methods.
Harvest of Hawaii crustacean management unit species in the U.S. EEZ is managed under the Fishery Ecosystem Plan FEP for the Hawaii Archipelago (Hawaii FEP) and implementing regulations under 50 CFR 665.240 through 665.259. The Hawaii FEP established mandatory permit and reporting requirements to facilitate monitoring of catch and effort. Federal regulations allow only trap and hand harvest methods, and lobsters cannot be taken by means of poisons, drugs, other chemicals, spears, nets, hooks, or explosives. Additionally, there are minimum size limits for spiny and slipper lobsters, and prohibitions against harvesting egg-bearing lobster, retaining mutilated or damaged lobsters, and fishing during the months of May through August, the peak lobster spawning season. Lobster harvest is also subject to an annual catch limit to prevent overfishing.
A commercial marine license issued by DAR is required for all commercial fishing activities. This fishery corresponds to the following fishing method(s) defined by DAR: trap/trap fishing (lobster trap). Hawaii Administrative Rules specify a minimum mesh size for traps: netting must be a minimum of 2 inches stretched mesh, and rigid material must be a minimum of 2 inches by 1 inch. Entrance cones for traps have no minimum mesh size. Traps must be portable and not exceed 10 feet in length or 6 feet in height or width. In state waters, the spiny lobster and slipper lobster fishery is closed from May – August. There are minimum size limits, and prohibitions against harvesting all females (spiny lobsters) or egg-bearing female lobsters (slipper lobsters). Lobsters must be landed in whole condition only, not mutilated.
