Abstract
Abundance and diversity of macroinvertebrates as well as physico-chemical
parameters of the water were investigated in five rivers of the Juru River Basin in
northern Peninsula Malaysia; Ceruk Tok Kun River (CTKR), Pasir River (PR),
Permatang Rawa River (PRR), Kilang Ubi River (KUR), and Juru River (JR). A total
of 23 macroinvertebrate genera and nine chironomid species including Chironomus
kiiensis, C. javanus, Polypedilum trigonus, Microchironomus sp., Dicrotendipes sp.,
Tanytarsus formosanus, Clinotanypus sp., Tanypus punctipennis and Fittkauimyia
sp. were identified. Except for C. javanus, the abundance of chironomid species
differed significantly among the rivers (Kruskal Wallis Test, P<0.05). Following the
water quality index (WQI), CTKR, PR and JR were classified as Class III (slightly
polluted rivers) while PRR and KUR fell in the Class IV (polluted) rivers.
