Stock assessment of swordfish (Xiphias gladius) in the Indian Ocean using A Stock-Production Model Incorporating Covariates (ASPIC)

A Stock-Production Model Incorporating Covariates (ASPIC) was used to conduct the stock assessment for swordfish in the Indian Ocean. The results indicated that the stock status became to be optimistic, and this may result from the obvious decline in catches in recent years, while the CPUE series revealed fluctuation with increasing or relatively flat trends. All scenarios of Fox models indicated that the current status of swordfish in the Indian Ocean may be not overfished and not subject to overfishing.
