Notes: LTPY is long-term potential yield or the maximum long-term average catch that can be achieved from the resource. This term is analogous to the concept of maximum sustainable yield. Stock level relative to LTPY is a measure of stock status. The present abundance level of the stock is compared with the level of abundance which on average would support the LTPY harvest. This level is expressed as below, near, above, or unknown relative to the abundance level that would produce LTPY. Demersal = bottom-dwelling fishes such as flounders, skates, and dogfish. Pelagic = mid-water fishes such as blue fish, anchovies, sardines, and squids. Anadromous = fishes which ascend rivers to spawn, such as salmon, shad, and striped bass. Invertebrate = lobsters, clams, scallops, shrimp, etc. Highly migratory = high-seas (oceanic) fishes such as tunas, swordfish, and billfishes. Coastal migratory = fishes that range from the shore to the outer edge of the U.S. continental shelf, such as king and Spanish mackeral, dolphin fish, and cobia. Reef fish = fishes that prefer coral reefs, artificial structures, and other hard bottom areas, such as snappers, groupers, and amberjacks. The reef fish fishery also includes tilefishes that prefer sand bottom areas. *Also includes armorhead.
