Water Quality Monitoring Of Golden Arowana (Scleropages Formosus) At Ornamental Aquaculture Farm, Bukit Merah, Perak.
Masters thesis, Universiti Sains Malaysia.
Abstract
Water quality monitoring for Arowana is to investigate the required water quality
that is suitable for the fish and hence encourage its breeding. The purpose is solely to
preserve this Malaysian heritage species since Bukit Merah is the only place where
Golden Arowana was found to be successfully bred. A number of 14 sampling points
were selected in series from upstream at Bukit Merah reservoir and end up
downstream at Sungai Kurau. There are eight parameters involved which is
temperature, conductivity, dissolved oxygen (DO), pH, ammoniacal nitrogen (NH3-
N), suspended solids (SS), chemical oxygen demand (COD) and biochemical oxygen
demand (BOD5). The monitored results were compared with the guidelines given by
Department of Fisheries (DOF) and Interim National Water Quality Standard
(INWQS) Class II. Result shows that the average for all sampling points were within
the required guidelines except for SS. The WQI for all sampling points at Bukit
Merah were classified as Class II. This signifies that WQI Class II is suitable for
Arowana production where a total of 346 of Arowana fish had been produced during
the monitoring period. Further, it indicates that water quality at Bukit Merah was not
polluted and the water quality from upstream (water source) towards the downstream
(water release) does not have a deteriorations effect due to the aquaculture activities.
