Abstract: 

Bayesian Surplus Production Model (JABBA) was used to conduct the stock assessment for swordfish in the Indian Ocean. This study was an updated analysis based on the Reference Model and model specifications of Parker (2020). The results indicated that the current status of swordfish in the Indian Ocean may be not overfished and not subject to overfishing, and only a negligible risk of being overfished may occur.
