- Objectives
- To estimate growth from data collected in the recent tagging cruses
- Background
- Estimates of growth are needed for YPR analysis and stock assessments
- Otolith data is unreliable for estimating growth of skipjack tuna
- Data is available from several recent tagging cruises
- Tag growth increment data can be used to estimate length-specific growth rates
- Relevance for management
- The estimates of growth will be used in YPR and/or stock assessment models to provide management advice
- Duration
- 12 months
- Workplan and status
- Develop model
- Apply model to updated data
- Present methods and results at SAC
- Publish paper
- Deliverables
- Report presented at SAC 2024
- Published paper
- Updated date: 01 May 2022
- Progress summary for the reporting period
- Growth analysis conducted
- Challenges and key lessons learnt
- No tagging data is available for large skipjack
- No aging data is available
- SAC-13 INF-J
- Comments
- The absolute age and asymptotic length could not be estimated from the tagging data
