^ 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
Several species of odontocetes have been reported as depredating bait or catch from hook-and-line fisheries (Shallenberger, 1981; Nitta and Henderson, 1993). Depredation behavior may increase the risk of marine mammals becoming hooked or entangled. Stranding records and other information suggest several odontocete species may be killed or injured in unidentified hook-and-line fisheries (Bradford and Lyman, 2015; Baird et al., 2014). However, at this time, no serious injuries or mortalities to any marine mammal have been attributed to commercial vertical line fishing. 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.
Distribution
Fishing occurs near drop-offs, deep ledges, offshore fish aggregating devices, or offshore seamounts and pinnacles in state and federal waters. In 2013, there were 11 fishing trips that reported using vertical line gear.
Gear Description
This fishery uses set line gear. Fishing using a vertical mainline, less than one nautical mile in length and suspended from the surface with a float, from which leaders with baited hooks are attached and ending with a terminal weight.
Management
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.
In federal waters, harvest of Western Pacific pelagic management unit species is managed in accordance with the Fishery Ecosystem Plan for Pacific Pelagic Fisheries of the Western Pacific Region and implementing regulations under 50 CFR 665.798 through 665.819.
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: vertical line.
