This study was conducted to determine the length-weight relationship of yellow-wing flyingfish, Cypselurus poecilopterus landed on the western coast of Surigao del Norte, Philippines. Sampling was performed from June 2018 to May 2019. A total of 959 fish samples were gathered and measured. Total length was measured to the nearest centimeter (cm), while weight was measured to the nearest grams (g). The parameters a and b of the length and weight relationship were estimated using the formula W= aLb which was transformed into logarithmic form Log W = Log a + b Log L. The correlation coefficient (r2) ranged from 0.877 to 0.963 indicating a strong correlation between length and weight. The b values were continually increasing from June (2.898) to March (3.499), which is within the range of 2.5 to 3.5. Pooled data of 959 fish samples have a strong correlation between length and weight and followed positive allometric growth.
