Abstract: This study investigated the breeding success of harlequin rasbora (Trigonostigma heteromorpha) in a controlled aquaculture environment using an induced spawning technique with the tiger barb (Puntius tetrazona) as a stimulant. The research aimed to determine the effectiveness of this technique in enhancing the spawning response of harlequin rasbora. The experiment was conducted using four different treatments: Rasbora were exposed to one pair, three pairs, or five pairs of tiger barb, with a control group receiving no exposure. The study's findings revealed that spawning occurred in the treatment involving three pairs of tiger barb as stimulants, as well as in the control group. However, spawning success was not significantly improved by the induced technique, as the harlequin rasbora in the control group spawned more frequently than those in the induced groups. Fecundity was relatively low across all treatments, with an average of 4 to 9 eggs per spawning event, significantly below the expected range of 80-300 eggs. Fertilization and hatching rates were high in successful spawns, with rates reaching up to 100%. The survival rate of larvae at 30 days was also high, indicating good larval rearing conditions. Water quality parameters, including temperature, pH, and dissolved oxygen, remained within acceptable ranges for harlequin rasbora throughout the study, although the temperature was slightly higher than the optimal range. The results suggest that while the induced spawning technique with tiger barb as stimulants did lead to spawning in harlequin rasbora, it did not significantly enhance spawning success compared to natural spawning conditions. Further research is needed to optimize spawning conditions and improve fecundity in captive breeding programs for harlequin rasbora.
