Abstract
Selaroides leptolepis is one of the most common pelagic fish, which has high market demand in Gorontalo. This study aimed to provide growth patterns and sex ratio of S. leptolepis male and female inhabiting Tomini Bay, Indonesia. Sampling was conducted monthly for six months, from April 2020 to September 2020. A fish sample of 1168 was taken randomly from Tomini Bay fishers who landed their catch at Kampung Tenda Fish Landing Site, Gorontalo City. The length and weight of fish were measured using a ruler (nearest 1 mm) and an analytical scale (nearest 0.01 g) separately. The results showed that almost all captured exhibited positive allometric growth (b > 3) and tended to be plump, except for the female in May 2020. The sex ratio between males and females during the sampling periods was 1: 1.17, which means the population proportion is not balanced. Such data are essential for establishing fisheries management in Tomini Bay.
