Challenges and key lessons learnt
  • Movement scenario is the largest axis of uncertainty in the south Pacific albacore assessment
  • The south Pacific albacore stock is healthy and the recent fishing mortality was much lower than the fishing mortality corresponding to MSY
  • Spawning biomass decreased fast in recent years due likely to high longline catch
  • The stock should be monitored in the future through for example stock status indicators and conduct another benchmark assessment in 3 or 4 years
