Abstract :Frigate tuna Auxis thazard insert ignore into journalissuearticles values(Lacepède, 1800); is the most dominant species caught by the multiple handline in the coastal and offshore fishing grounds of Tawi-Tawi, southern Philippines. In this study, we investigated the size distribution, length-weight relationship, and catch per unit effort of frigate tuna insert ignore into journalissuearticles values( A. thazard ); in Tawi-Tawi waters, southern Philippines, caught using multiple handline. A total of 383 frigate tuna fish were sampled with a size distribution insert ignore into journalissuearticles values(total length); ranging from 16.5 to 34 cm. The length-weight relationship of frigate tuna was W=8×10 -3 ×TL 3.139 , where the b value of 3.139 indicates a positive allometric growth pattern. The catch per unit effort of the used gear was 2.49±0.52 kg/hr.
