Abstract: The study was conducted to assess the biological aspects of yellowfin tuna (Thunnus albacares) caught using hook and line in Dilasag Bay, Dilasag, Aurora, Philippines from July to September 2019. A total of 283 yellowfin tuna (total weight of 12,231.53 kg) was caught in Dilasag Bay by the 10 municipal fishermen in their 283 fishing trips. Large size yellowfin tuna (>110 cm) were commonly caught in Dilasag Bay. The monthly and combined growth data of the fish was described as negative allometric (b <3); the organism grows slender, so it gains length faster than weight. The length-weight relationship equation for the combined catches was W = 2.240 L1.129. The over-all value of condition factor (K), growth rate constant (k) and maximum length (L∞) of yellowfin tuna were 1.88±0.12, 0.157 kg/year and 145.117 cm, respectively.
