Journal: Fisheries
Year: 2022

The population biomass, fishing mortality dynamics and reference points of the rational exploitation of the Black-Azov sea shad during the period 2004-2020 were evaluated using the JABBA surplus production model in “catch-only” version. IUU estimation and preliminary parametrization by CMSY model was performed to improve assessment accuracy. According to the model output, during the 2004-2020 period shad stock biomass was in interval 1315-1341 t, fishing mortality in range 0,03-0,38. During the
