This study presents the first report on the bbiological characteristics of the Dolphinfish (Coryphaena hippurus Linnaeus, 1758) in the Libyan coast. Samples were collected from Fishing ports in the western Libyan coast, during the period from August to November (2021). The total length and weight ranged from 28 to 85cm (mean 48.98 cm), and 141.6 to 3654 (mean 838.62 g) respectively. The growth in the relationship of height and weight was homogeneous isometric (W = 0.0081L3.02), and the strength of the correlation between height and weight was strong (R2 = 0.98). As for the highest value of the gonad somatic index (GSI), it was in October (0.28), and the monthly average of the condition factor (CF) for the three months August, September and October, respectively (0.84, 0.92, 0.88), and the sex ratio of males to females was (1: 2), and by examining the stages Sexual maturity the spawning period is between September and October.
