Fisheries Glossary - S


s - See survival rate.

SAFE - See stock assessment and fishery evaluation report.

SEFC - See Southeast Fisheries Center.

SPR - See spawning potential ratio.

SSBR - See spawning stock biomass per recruit.

SSC - See scientific and statistical advisory committee.

Scattergram - A graph that shows how factors relate to each other. This is visual, not statistical, and is used when it is necessary to compare two factors, like fish age and size.

Scientific Assessment Panel - A group of biologists, economists, and sociologists put together by a federal fishery management council to review scientific data on the condition of a stock of fish and the interests of the fishermen and seafood processors who use the stock. Panel members generally come from universities and state and federal fisheries agencies.

Scientific and Statistical Advisory Committee - A group of scientific and technical people giving advice to a council.

Secretarial Management Plan - A term used to describe a plan developed by the Secretary of the U.S. Department of Commerce in response to an emergency, a council’s failure to act, *or for highly migratory species.

Selectivity - The ability of a type of gear to catch a certain size or kind of fish, compared with its ability to catch other sizes or kinds.

Simulation - An analysis that shows the production and harvest of fish using a group of equations to represent the fishery. It can be used to predict events in the fishery if certain factors changed.

Size Distribution - A breakdown of the number of fish of various sizes in a sample or catch. The sizes can be in length or weight. This is mot often shown on a chart.

*Shellfish - General term for crustaceans and mollusks.

Slot Limit - A limit on the size of fish that may be kept. Allows a harvester to keep fish under a minimum size and over a maximum size, but not those in between the minimum and maximum. *Can also refer to size limits that allow a harvester to keep only fish that fall between a minimum and maximum size.

Social Impacts - The changes in people, families, and communities resulting from a fishery management decision.

Socioeconomics - A word used to identify the importance of factors other than biology in fishery management decisions. For example, if management results in more fishing income, it is important to know how the income is distributed between small and large boats or part-time and full-time fishermen.
