Between January 2023 and March 2024, 647 distinct Pomadasys stridens specimens were captured in the coastal waters of Syria in the eastern Mediterranean Sea. Advanced analysis techniques, such as artificial neural networks and fuzzy logic, were applied to these samples. During the study, the largest captured individual was 19.17 cm long and was estimated to be 8 years. By applying the von Bertalanffy growth equation to the total length data, had derived the formula TLt = 21.53 (1-e-0.23 (t + 1.29)), which indicates positive allometric growth (b = 3.08). The growth performance index (Φ’) was calculated as 2.03, providing a measure of growth efficiency. The study also estimated various mortality coefficients for Pomadasys stridens. The coefficients were as follows: Z = 0.92 y-1 (total mortality rate), F = 0.23 y-1 (fishing mortality rate), M = 0.69 y-1 (natural mortality rate), and E = 0.25 y-1 (exploitation rate). The survival coefficient (S) was determined to be 0.40 y-1. Analysis of the population growth (FP) of Pomadasys stridens from the Syrian coast, a value of 34, indicated a moderate growth rate within the local marine environment. However, the study also found that fisheries were exploited at a fishing vulnerability of 50.9. The population dynamics of Pomadasys stridens in Syrian seawater can be gleaned from the findings of this study. The sustainable management of this species requires the implementation of conservation measures, according to them. In addition, the results enrich our knowledge of Pomadasys stridens’ growth, mortality, and vulnerability to fishing, creating the basis for future research and management strategies.
