Abstract

Lizardfish Saurida undosquamis is one of the most popular fishes inhabiting the Red Sea and migrated then widely distributed in the Mediterranean Sea Monte Carlo method-based Surplus Production Model CMSY was used to predict the biological reference points PRBs for S unodsquamis using catch and catch per unit of effort time series data 1980-2021 The Biological Reference Points for S unodsquamis are MSY 1 4 1000ton B BMSY 0 629 Exploitation F FMSY 1 29 Carrying Capacity k 18 2 1000ton The intrinsic growth rate of the fish population r 0 304 y-1 Such information constructs the base to set up a reliable strategy to rebuild the stock and avoid the management side effects on the community of the fishermen
