^ 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.
Basis for Current Classification
No mortality or serious injury of marine mammals has been documented in the fishery. Based on the similarity of this fishery to the Hawaii troll fishery, this fishery has a remote likelihood of marine mammal mortalities or serious injuries.
Distribution
Fishing can occur in local nearshore or federal waters year-round, with trips lasting less than a day. The troll fleet consists primarily of vessels less than 24 ft in length, which typically cannot venture more 20 miles from Saipan, although larger vessels (>40 ft) engaged in multi-day bottomfish trips to offshore banks in federal waters and to the islands north of Saipan may also troll between bottomfish fishing grounds.
In 2012, the last year for which data is available, an estimated 35 commercial fishing vessels engaged in pelagic trolling, making 932 trolling trips that commercially landed pelagic species (WPFMC 2014).
Gear Description
Fishing by towing or dragging line(s) with artificial lure(s) or dead or live bait, or green stick and danglers using a sail, surf or motor-powered vessel underway. Can include trolling with bait (dead or alive), trolling with artificial lure, or trolling with green stick.
Generally four to five but occasionally more than six individual lines rigged with artificial lures may be trolled when outrigger poles are used to keep gear from tangling. Lures are generally trolled at 7 – 8.5 knots. When using live bait, trollers move at slower speeds to permit the bait to swim naturally. Pelagic trollers generally fish at an average distance of 5 to 8 miles from shore, with maximum distance of about 30 miles from shore, with some exceptions. Trollers fish where water masses converge and where submarine cliffs, seamounts, and other underwater features dramatically change the bathymetry. Trollers often fish drifting logs, other flotsam, underneath bird aggregations, and near FADs.
Management
In federal waters, the fishery is managed in accordance with the Fishery Ecosystem Plan (FEP) for Pacific Pelagic Fisheries of the Western Pacific Region and implementing regulations under 50 CFR 665.798 through 665.819. Federal regulations in 50 CFR 665.900 through 665.906 prohibit all commercial fishing around the three northernmost islands, Uracas, Maug, and Asuncion, which together comprise the Islands Unit of the Marianas Trench Marine National Monument. Non-commercial fishing for pelagic species is allowed within the Islands Unit subject to federal permit and logbook reporting requirements.
The Commonwealth of the Northern Mariana Islands has not promulgated regulations specific to pelagic trolling, but prohibits or regulates certain fishing gear and regulates fishing in certain areas (e.g., marine protected areas), which may also apply to this fishery.
