Climate anomaly opposite to El Niño with unusually cold ocean temperatures in the Equitorial Pacific, leading to warmer winter temperatures in the southeastern United States and cooler temperatures in the Pacific Northwest. La Niña events occur after some, but not all El Niño events.

1. Separability is the assumption, made in some age-structured stock assessment models (used to track changes in fishing mortality by fish age and by fishing year) that the fishing mortality matrix can be partitioned into two components: An age-specific component that does not vary over time (i.e. a constant exploitation pattern), and an annual multiplier that scales the age-specific pattern up or down; 2. Independence among resources and in economics; an ability to substitute environmental inputs in order to produce outputs. Therefore, these resources may be managed or utilized separately due to the lack of strong linkages to other large marine ecosystem (LME) components.
Industry:Fishing
A part of the range of a stock that is not accessible to fishing. If the species in question is not too diffusive, the existence of such refuges may enable it to persist under a higher level of fishing mortality than it otherwise would.
Industry:Fishing
A model describing the dynamics of a species that does not explicitly incorporate the effects of interactions with other species.
Industry:Fishing
A group of freshwater and saltwater invertebrates with jointed legs and a hard shell of chitin. Includes shrimps, crabs, lobsters, and crayfish.
Industry:Fishing
A fishing boat that takes recreational (sport) fishermen out for a fee per person. Different from a charter boat in that people on a head boat pay individual fees as opposed to renting the boat.
Industry:Fishing
Areas within a Marine Protected Area (MPA) that are crucial to achieving the objectives of the MPA; for example, spawning areas in an MPA established for fisheries purposes.
Industry:Fishing
Anything changeable. A quantity that varies or may vary. Part of a mathematical expression that may assume any value.
Industry:Fishing
Cost accounting based on market prices as opposed to opportunity costs.
Industry:Fishing
A type of fishery in which fishers target only one species of fish, although it is usually impossible not to catch others incidentally.
