Aquatic insects as bio-indicators of water quality – a study on Sungai Kawal, Johor National Park of Endau-Rompin, Peninsular Malaysia

Summary: | Biological indicator species or bio-indicators are sensitive to specific environmental
factors so that changes in their environment will be reflected by their incidence or abundance. In
fact, aquatic insects of freshwater river and stream ecosystems have been widely used as bioindicators
to examine the species-habitat relationship with regard to the water quality of the
habitat. Therefore, this study attempted to determine species richness of aquatic insects in Sungai
Kawal, Johor National Park of Endau-Rompin (TNJER), Mersing, Johor, Malaysia; to identify
traditional knowledge (TK) used by Jakun tribe in Kampung Peta, TNJER for maintaining rivers
and streams at good level; and then to correlate the relationship between the scientific perspective
and TK perspective. Aquatic insects were collected and sampled by using kick sampling
technique and D-framed net. Throughout the study, a total of 618 individuals consisting of 23
families belonging to seven orders of aquatic insects were reported. The documentation of TK
was done by interviewing 10 total respondents of the Jakun tribe in Kampung Peta. Physical
features of Sungai Kawal were also recorded during sampling. The correlation between the
scientific perspective and TK perspective regarding how the ecosystem maintenance by the
Jakun tribe has contributed to an excellent habitat for the aquatic insects to breed and multiply.
The number of species recorded indicated the good status of water quality of Sungai Kawal based
on science and then supported by TK of the Jakun tribe of Kampung Peta. Furthermore, the
findings also suggested a good correlation between the scientific perspective and TK perspective,
and the significant contribution of TK of the Jakun tribe to the management of natural resources. |
