Abstract

Understanding spawning habitat of the fish is an important consideration for the management of fish populations. Fish and environmetal variables data were undertaken in the Sibau Watershed, Betung Kerihun National Park in monthly from July 2013 to October 2013 and continued in bimonthly from July to November 2014. Environmental variables in the sampled areas were measured at each station sampling. A total 107 individuals of H. bimaculata were caught by anglings (76 individual) and gill nets (31 individuals) during sampling periods. The sex ratio for mature both sexes was 1.00: 2.37 (M:F). Relative abundance by angling method showed that population H. bimaculata was more abundant than other fish population. The potenstial spawning sites of the fish were in the upper Menjakan river and in the upper Apeyang river. Analysis of linier model showed that abundance of H. bimaculata is significantly positively correlated with water velocity, and negatively correlated with water depth.
