Otoliths. Bone-likestructuresformedintheinnerearoffish.Theringsorlayerscanbe counted to determine age.
Otter trawl. Demersal trawl operated by a single vessel in which the net is held open horizontally by angle-towed otter boards (large rectangular ‘boards’ of timber orsteel)andverticallybyacombinationoffloatsontheheadropeandweightson the ground line. Attached between the head and ground ropes and the towing warps, the otter boards are spread apart by the hydrodynamic forces acting on them when the net is towed.
Output controls. Management measures that place restraints on what is caught, including total allowable catch, quota, size limits and species.
Overfished.Afishstockwithabiomassbelowthebiomasslimitreferencepoint.‘Notoverfished’impliesthatthestockisnotbelowthethreshold,andisnowusedinplaceofthestatusclassificationsof‘fullyfished’or‘underfished’thatwereusedinearlier editions of Fishery status reports.
Overfishing, subject to.Astockthatisexperiencingtoomuchfishing,andtheremoval rate from the stock is unsustainable. Also:
• Fishing mortality (F) exceeds the limit reference point (FLIM). When stock levels are at or above BMSY, FMSY, will be the default level for FLIM.
• Fishing mortality in excess of FLIM will not be defined as overfishing if a formal ‘fish down’ or similar strategy is in place for a stock and the stock remains above the target level (BTARG).
• When the stock is less than BMSY but greater than BLIM, FLIM will decrease in proportion to the level of biomass relative to BMSY.
• At these stock levels, fishing mortality in excess of the target reference point (FTARG) but less than FLIM may also be defined as overfishing, depending on the harvest strategy in place and/or recent trends in biomass levels.
• Any fishing mortality will be defined as overfishing if the stock level is below BLIM, unless fishing mortality is below the level that will allow the stock to recover within a period of 10 years plus one mean generation time, or three times the mean generation time, whichever is less.
• Any directed (targeted) fishing of an overfished stock (stock level is below BLIM) will amount to overfishing.
PPair trawling. Trawling by two vessels steaming in parallel with the net towed between them. Very large nets can be held open and towed in this way. The net is generally hauled alternately aboard the two vessels for processing of the catch.
Parameter. Characteristic feature or measure of some aspect of a stock, usually expressed as a numerical value (e.g. see M (natural mortality)).
Parental biomass. Weight of the adult (reproductively mature) population of a species. See also SB (spawning biomass).

Fishery status reports Status of key Australian fish stocks reports
Biomass Fishing mortality Stock status
Not overfished + Not subject to overfishing
= Sustainable
Overfished + Not subject to overfishing
= Transitional–recovering a
Not overfished + Subject to overfishing = Transitional–depleting
Overfished + Subject to overfishing = Overfished b
Uncertain OR Uncertain = Undefined
a For a stock to be considered transitional–recovering in the national reports there must also be evidence that the biomass is recovering (i.e. increasing). b If the Commonwealth reports classify a stock as ‘overfished’ and ‘not subject to overfishing’ but there is no evidence that biomass is recovering it would be considered as ‘overfished’ in the national reports rather than ‘transitional–recovering’.
