| Abstract | ||
| This study aimed to determine the reproductive biology of Upeneus pori along the Benghazi coast, Mediterranean Sea, eastern Libya, by contrasting the present findings with those of previous investigations. This involved figuring out fecundity, length at initial sexual maturity, gonado somatic index, and sex ratio. Monthly samples of Upeneus pori were collected from commercial trawl captures in the Mediterranean Sea off the coast of Benghazi between January and December 2024. The overall sex ratio for Upeneus pori was 1: 1.24 (M: F). At 50% maturity, Upeneus pori males measured 10.1cm in length, while females measured 10.2cm. The spawning behavior was analyzed based on the gonad somatic index. The highest GSI values for both males and females were recoreded from March till July. Upeneus pori spawned during the spring and summer season. Approximately 60 mature ovaries were used to estimate Upeneus pori's absolute fecundity. The mean absolute fecundity ranged from 6791 ± 566 to 70285 ± 3426 with an average of 39118 ±1447, and the average fish length varied from 9.5 to 17.4cm. | ||
