| description | The study was conducted from November 2018 to October 2019 in Diatas Lake, Solok, West Sumatra, Indonesia. This study aimed to determine some aspects of the reproductive biology of Cyclocheilichthys armatus, based on the observation of 882 male and 844 female specimens. The results showed that the sex ratio of C. armatus was well balanced (1.05:1). This species is a total spawner and it spawned twice a year at the end of the rainy season. The peak of spawn occurred in December 2018 and June 2019. The total lengths of gonads at first maturity in C. armatus were 165.5±0.003 mm (males) and 128.7±0.004 mm (females). The absolute fecundity varied between the gonadal maturity stages (GMS), ranging from 11,601 to 15,773 eggs individual-1 (GMS III) and from 10,801 to 12,293 eggs individual-1 (GMS IV) and the relative fecundity ranged from 133-154 eggs g-1 bodyweight (GMS III) and 75-91 eggs g-1 bodyweight (GMS IV). The C. armatus fecundity had a positive correlation with the total length of fish, bodyweight and gonadal weight. |
