Abstract
Keudawah (Rasbora sp.) is a native species found in freshwater, especially Krueng Lanca of Aceh Province, Indonesia. Length-weight relationships (L-WR) and condition factor studies are significant in fisheries, as they offer invaluable insights into fish growth, general welfare, and fitness, especially in freshwater habitats. This study aims to evaluate the fish’s length-weight relationship and condition factor, which can be used to establish monitoring and management systems for this species. Sampling was conducted purposively every month from January to June 2023 at six stations using gill and cast nets. Sampling results were then analyzed in the laboratory. 1118 individual fish (632 males and 486 females) were collected from Krueng Lanca, Aceh Province, with a length frequency of 34-112 mm for males and 46-135 mm for females. The results showed that keudawah had negative allometric growth (both males and females), with b values ranging from 2.307 to 2.962 (for males) and 1.731 to 2.669 (for females). The condition factor (Kn) fluctuated between 0.84 and 0.93 (for males) and 0.82 to 0.94 (for females), indicating less than optimal conditions for this species.
