Abstract:In this study, Stock Synthesis (SS) was used to conduct the stock assessment for
striped marlin in the Indian Ocean by incorporating historical catch, CPUE and
length-frequency data. The influences of CPUE series, time-varying catchability and
selectivity assumption and life-history parameters on the assessment results were
examined by various scenarios. The results of most scenarios indicated that the
current stock status of striped marlin in the Indian may be overfished and overfishing
already, except for the scenario of incorporating CPUE series of Iran and Pakistan.
