Geographic information system An integrated technology that enables management, analysis, and mapping of geographical information. In the fishery context, possible GIS applications are countless — as for example tracking foraging and migratory patterns of marine species, monitoring fishing vessel activities, analyzing fishing catch and effort,…

Fishing mortality at the maximum sustainable yield The level of fishing intensity that, if applied constantly year after year, would result in the maximum sustainable yield (MSY).

Fishing mortality at the maximum economic yield The level of fishing intensity that produces the maximum economic yield (MEY).

Fish carrying capacity Measured for most tuna fishing vessels as the tonnage of fish that can be stored on the vessel when it is fully loaded, expressed in metric tons (mt). Although it is related to the size of the fish wells, the actual tonnage…

(Instantaneous) Fishing mortality rate A measure of the intensity with which a stock is being exploited. This is the fraction of the fish population (or other defined group) that is expected to be caught at any single point in time. See also Natural mortality, FMEY,…

Ecological risk assessment A procedure that scientifically evaluates the probability that adverse ecological effects occur on ecosystems, and on components of ecosystems, as a result of exposure to specific stressors. In the fishery context, this assessment is used to identify the risks of fisheries activities…

Endangered, threatened or protected species Designation used in some countries for vulnerable species such as marine mammals, sea turtles, and others.

Decision analysis A formal analysis to aid decision‑making in the face of uncertainty. A decision analysis usually evaluates the relative likelihood that alternative management actions (e.g., average catch, constancy of catch, probability of rebuilding to a given biomass target, etc.) will achieve the expected outcomes….
