Abstract: (34 Views)
Recent years have witnessed considerable fluctuations in the stock of Silver pomfret, Pampus argenteus, in the Persian Gulf, resulting in a noticeable decline in its catch. Analyses of length–weight relationships and condition factors are essential tools in stock assessment and the conservation of commercially valuable and threatened fish species. This study investigated the relationship between fork length and body weight, as well as the condition factor, of P. argenteus in the coastal waters of Hormozgan Province, Iran. Fish samples were collected using bottom trawl nets, and a total of 72 specimens were examined. The fork length–weight relationship was estimated using Pauly’s empirical equation and the coefficient of determination (R²). The condition factor (CF) was calculated using the equation CF = 100 × W / FL³. The results showed that the mean fork length (FL) and mean body weight of the sampled fish were 13.5 cm and 89.5 g, respectively. The combined length–weight relationship for samples collected from both fishing sites was estimated as W = 0.0847 × L²·⁶⁶, indicating negative allometric growth. Fish from both study sites (Kuhestak and Darsorkh), as well as the pooled samples, exhibited negative allometric growth patterns. The overall condition factor was calculated as 3.5. Length-frequency analysis revealed that more than one-fourth of the captured specimens were close to or below the length at first sexual maturity. These findings highlight the need to revise current management and stock-monitoring strategies for this valuable species. In addition, the implementation of temporal and size-based fishing restrictions is recommended to support the sustainable exploitation and conservation of P. argenteus populations in the Persian Gulf.
