4 Level 2: PSA (Productivity and Susceptibility Analysis) db dt B = rb(1 ) K qeb Productivity, r - recovery rate after potential depletion or damage by the fishing activity Susceptibility, q - extent of the impact due to fishing activity
5 Purpose Assessment on the adverse impacts of the Korean tuna longline fishery in the Western and Central Pacific Ocean - target species, non-target species and dependent or associated with the target species Precautionary approach for the stock or ecosystem management and conservation - identification of non-target species for consideration of future research or management - protect biodiversity in the marine environment

18 Conclusion Not only target tuna species were influenced by the tuna longline fishery, but also non-target species were affected by the fishery WCPFC This study Blue shark- tunas: medium risk Galapagos shark Oceanic white-tip - billfishes: shark medium or high Longfin risk mako Shortfin mako - sharks: high risk Scalloped hammarhead shark Thresher shark Oceanic white-tip shark - turtles: : medium or high risk - others: medium or high risk
19 Conclusion For reducing non-target species I. Development and improvement of long-term data collection, monitoring and research programmes II. Enhancement and development of methodology - more robust assessment III.Identification of captured non-target species by other tuna fisheries such as purse seine or pole-and-line Provide wider scientific advices to the policy makers and stakeholders
