Hawaii Offshore Pen Culture Fishery - MMPA List of Fisheries
U.S. fisheries are classified under the Marine Mammal Protection Act according to the level of interactions that result in incidental mortality or serious injury of marine mammals.

Hawaiian monk seal |
Basis for Current Classification
The total annual mortality and serious injury of Hawaiian monk seals in this fishery is greater than 1% and less than 50% of the stock’s Potential Biological Removal (PBR) level.
Distribution
Offshore aquaculture operations are primarily conducted in state waters less than 2 miles from shore on the leeward side (southwest) of the Oahu and Hawaii Island as these areas are protected from the predominant northeasterly trade winds. Since added to the LOF in 2006, there have been fewer than three offshore aquaculture operations annually.
Gear Description
Aquaculture is the controlled propagation and rearing of aquatic organisms for any commercial, recreational, or public purpose. This definition covers all production of finfish, shellfish, plants, algae, and other marine organisms for 1) food and other commercial products, 2) wild stock replenishment for commercial and recreational fisheries, 3) rebuilding populations of threatened or endangered fin-fish species under species recovery and conservation plans, and 4) restoration and conservation of marine and habitat.
In Hawaii, offshore pen culture (or open ocean aquaculture) is a type of aquaculture that involves using a three-dimensional pen, net, or cage-type enclosure either, moored or unmoored to cultivate, catch, and harvest the fish. Typically, juvenile fish from a wild or hatchery-produced stock are grown out in this enclosure to a desired sized and then harvested. Offshore pen culture does not include the Hawaii fishponds.
Management
The Fishery Ecosystem Plan (FEP) for the Hawaii Archipelago and implementing regulations under 50 CFR 665.220 through 665.239 include a list of allowable gear and methods for harvesting Hawaii coral reef ecosystem management unit species (MUS) in the FEP management area (U.S. EEZ, outside of state waters). Use of gear or a method not listed as allowable requires a special permit pursuant to 50 CFR 665.224(1)(iii). Offshore aquaculture pens are not listed as allowable gear, and require a special permit under the FEP if operating in federal waters and are used to harvest Hawaii coral reef ecosystem MUS. Depending on size and location, offshore aquaculture in federal waters may require federal permits from the U.S Army Corp of Engineers, U.S Coast Guard, and Department of Health.
In addition to federal permits, offshore aquaculture in state waters require a State of Hawaii aquaculture license, and Conservation District Use Permit both issued by the Department of Land and Natural Resources and a special management area permit from the affected county.

Basis for Original Classification |
Listed as Category III because the fishery was expected to have a remote likelihood of incidental serious injury or mortality of marine mammals. No observer, logbook, or stranding data were available. |
