Glossary 



INTERNAL WATER PROCESSING (IWPs). An 



operation in which a foreign vessel is authorized by the 

 governor of a state to receive and process fish in the 

 internal waters of a state. The Magnuson Act refers to 

 internal waters as all waters within the boundaries of a 

 state except those seaward of the baseline from which the 

 territorial sea is measured. 



JOINT VENTURE. An operation authorized under 

 the i\Ih'Ci\L\ (Magnuson Act) in which a foreign vessel 

 is authorized to receive fish from U.S. fishermen in the 

 U.S. EEZ. The fish received from the U.S. vessel are part 

 of the U.S. harv^est. 



LANDINGS, COMMERCIAL. Quantities of fish, 

 shellfish, and other aquatic plants and animals brought 

 ashore and sold. Landings of fish may be in terms of 

 round (live) weight or dressed weight. Landings of 

 crustaceans are generally on a live-weight basis except for 

 shrimp which may be on a heads-on or heads-off basis. 

 Mollusks are generally landed with the shell on, but for 

 some species only the nieats arc landed, such as sea 

 scallops. Data for all mollusks are published on a meat- 

 weight basis. 



MAGNUSON-STEVENS FISHERY CONSER- 

 VATION AND MANAGEMENT ACT, Public 

 Law 94-265, as amended. The Magnuson-Stevens Act 

 provides a national program tor the conservation and 

 management of fisheries to allow for an optimum yield 

 (CV) on a continuing basis and to realize the full potential 

 of the Nation's fisher)- resources. It established the U.S. 

 Exclusive Economics Zone (EEZ) (formerly the FCZ - 

 Fishery Conservation Zone) and a means to control 

 foreign and certain domestic fisheries through PMPs and 

 FMPs. Witiun the U.S. EEZ, the Umted States has 

 exclusive management authority over fish (meaning fin- 

 fish, mollusks, crustaceans, and all other forms of manne 

 animal and plant life other than manne mammals, birds, 

 and highly migratory species of tuna). The Magnuson Act 

 provides further exclusive management authority be- 

 yond the U.S. EEZ for all continental shelf fishery 

 resources and all anadromous species throughout the 

 migrator)' range of each such species, except during the 

 time thevare found within anv foreign nation's territorial 

 sea or fishen' consen-ation zone (or the equivalent), to tlie 

 extent that such a sea or zone is recogmzed by the United 

 States. 



MARINE RECREATIONAL FISHING. Fishmg 

 for pleasure, amusement, relaxation, or home consump- 

 tion. 



MARINE RECREATIONAL CATCH. Quantiues 

 of finfish, shellfish, and other living aquatic organisms 

 caught, but not necessarily brought ashore, by manne 

 recreational fishcnnan. 



MARINE RECREATIONAL FISHERMEN. 



Those people who fish in manne waters prunanly for 

 recreational purposes. Their catch is pnmanly for home 

 consumption, although occasionally a part or all of their 

 catch may be sold and enter commercial channels. This 

 definition is used in the NMFS Marine Recreational 

 Fishery Statistics Survey, and is not intended to represent 

 a NMFS poUcy on the sale of angler-caught fish. 



MAXIMUM SUSTAINABLE YIELD (MSY). 



MSY from a fisher)- is the largest annual catch or yield in 

 terms of weight of fish caught by both commercial and 

 recreational fishermen that can be taken continuously 

 from a stock under existmg environmental conditions. A 

 determination of MSY, which should be an estimate 

 based upon the best scientific information available, is a 

 biological measure necessan' in the development of 

 optimum yield. 



METRIC TONS. A measure of weight equal to 1,000 

 kilograms, 0.984 long tons, 1 . 1 02.3 short tons, or 2,204.6 

 pounds. 



MOTORBOAT. A motor-driven commercial fishing 

 craft having a capacit)- of less than 5 net tons, or not 

 officially documented by the Coast Guard. See "boat, 

 other". ' 



NORTHWEST ATLANTIC FISHERIES OR- 

 GANIZATION (NAFO). This convention, entered 

 into force Januar)- 1, 1979, replaces ICNAF. NAFO 

 provides a forum for continued multilateral scientific 

 research and investigation of fishery resources that occur 

 beyond the limits of coastal nations' fishery jurisdiction in 

 the northwest Atlantic, and will ensure consistency be- 

 tween NAFO management measures m tliis area and 

 those adopted by the coastal nations within the Umits of 

 their fishen' jurisdiction. 



OPTIMUM YIELD (OY). In the MFCMA 

 (Magnuson Act), OY with respect to the yield from a 

 fisher)', is the amount of fish that (1) will provide the 

 greatest overall benefit to the United States, with particu- 

 lar reference to food production and recreational op- 

 portunities; and (2) is prescribed as such on the basis of 

 maximum sustainable yield from such fishery, as modi- 

 fied by any relevant ecological, economic, or social 

 factors.
