Freshwater fishes in Peninsular Malaysia are relatively
diverse. Of approximately 1000 species in the South-East
Asian Tropics, more than 200 species can be found in
Peninsular Malaysia (Ismail and Sabariah 1995). However,
this situation is likely to increase as further discoveries are
made (Kottelat and Lim 1992; Ng and Lim 1993; Ismail and
Sabariah 1995; Tan 1998; Ng 2002; Ng 2003; Tan and Ng
2005). Recent studies showed that 470 species comprising
15 families have been recorded in Malaysia (Chong et al.
2010).
Temengor Reservoir, which is the second largest
man-made reservoir in Peninsular Malaysia, provides
an environment that supports diverse fish assemblages.
Sungai Enam (Sungai = River) and Sungai Telang, which
flow into Temengor Reservoir (Figure 1), were last logged
40 years ago. Despite the negative impacts of logging,
water quality in these two headwaters has recovered and
is classified as Class I (Hashim et al. 2011).
Due to poor documentation of Malaysia freshwater
fishes as mentioned by Chong et al. (2010), we present a
checklist of fish community, which was generated from a
study conducted from June 2003 to May 2004 along Sungai
Enam and Sungai Telang. Spatial analyses involving interand
intra-river comparisons on fish indices are presented.
In temporal analyses, fish assemblage data from 1993 to
2011 were compiled and compared for inventory checklist
and future reference purposes.
