Abstract

Batang Ai Hydroelectric Dam Reservoir is a first man – made lake in Sarawak. Although the water quality in Batang Ai Hydroelectric Dam Reservoir have been assessed yearly but there is less scientific studies on surface waters and the vertical profile of temperature and conductivity at selected Cage Culture area and Non – Cage Culture of Batang Ai Hydroelectric Dam Reservoir. Therefore, the objective of this study was to identify and illustrate the vertical profile of temperature and conductivity at Cage Culture and Non – Cage Culture Area of Batang Ai Hydroelectric Dam Reservoir. Moreover, to elucidate the surface waters using Current Meters.. In this study, 24 stations were servey for profiling of stratification of temperature and conductivity; 13 stations were conducted for surface current. Results show there were significant dropped in temperatures for all stations range from 24.9 to 32.2 0C from Epilimnion to Hypolimnion Layer (P<0.05). Meanwhile, vertical profile of conductivity fluctuated; increasing with depth as from Eplimnion reaching out to Hypolimnion. There was significant higher in conductivity in Cage Culture Area compared to Non – Cage Culture Area (P<0.05). Hypolimnion layer hold the highest conductivity of all layers. As for surface current, it was found that the mean of surface current was 42.15 ± 19. 96 cm/s. Circulated in a clockwise manner as influenced by the Coriolis‟s effect and prevailing wind of trade. This study could help to provide the robust management tools for aquaculturist and management
