  abstract = {{P}roductivity and {S}usceptibility {A}nalysis ({PSA}) is a methodology for evaluating the vulnerability of a stock based on its biological productivity and susceptibility to fishing. {I}n this study, we evaluated the vulnerability of 60 stocks of tuna, billfishes and other teleosts caught by the tuna longline fleets operating in the {S}outh {A}tlantic and {I}ndian {O}cean using a semi-quantitative {PSA}. {W}e (a) evaluated the vulnerability of the species in the study areas; (b) compared the vulnerability of target and non-target species and oceans; (c) analyzed the sensitivity of data entry; and (d) compared the results of the {PSA} to other fully quantitative assessment methods. {I}stiophoridae exhibited the highest scores for vulnerability. {T}he top 10 species at risk were: {A}tlantic {I}stiophorus albicans; {I}ndian {O}cean {I}stiompax indica; {A}tlantic {M}akaira nigricans and {T}hunnus alalunga; {I}ndian {O}cean {X}iphias gladius; {A}tlantic {T}. albacares, {G}empylus serpens, {R}anzania laevis and {X}. gladius; and {I}ndian {O}cean {T}. alalunga. {A}ll species considered at high risk were targeted or were commercialized bycatch, except for the {A}tlantic {G}. serpens and {R}. laevis which.were discarded, and may be considered as a false positive. {T}hose species and others at high risk should be prioritized for further assessment and/or data collection. {M}ost species at moderate risk were bycatch species kept for sale. {C}onversely, species classified at low risk were mostly discarded. {O}verall, species at high risk were overfished and/or subjected to overfishing. {M}oreover, all species considered to be within extinction risk ({C}ritically {E}ndangered, {E}ndangered and {V}ulnerable) were in the high risk category. {T}he good concordance between approaches corroborates the results of our analysis. {PSA} is not a replacement for traditional stock assessments, where a stock is assessed at regular intervals to provide management advice. {I}t is of importance, however, where there is uncertainty about catches and life history parameters, since it can identify species at risk, and where management action and data collection is required, e.g. for many species at high and most at moderate risk in the {S}outh {A}tlantic and {I}ndian oceans.},
