Stock assessment for Mullus barbatus using catch-based (CMSY) and length based (LBB, LBSPR and LIME) data limited models were performed by using official catch statistics and commercial length frequency data from northeastern Mediterranean. The CMSY model results showed that the catch amount did not exceed MSY, and the fisheries reference points (B/BMSY and F/FMSY) indicated a healthy stock status in 2020. The LBB model results indicated that the biomass ratio was above safe biological limits (B<0.5 BMSY) but fishing mortality was slightly higher than natural mortality. Likewise, LBSPR results showed that SL50 for red mullet was higher than its Lm50, while the estimated median SPR was above the limit of 20% set as the biological reference p...
