This study was conducted to identify sciaenid species collected from Sarawak
specifically surrounding Kuching city. Throughout this study, 18 species from 9 genera
of scaienids were identified which are Pennahia, Panna, Protonibea, Nibea, Chrysochir,
Sonorulux, Otolithoides, Otolithes and Johnius. There were 28 parameters of
morphometric measurement and meristic count were used to get the data of the
species. From this study, there were two unidentified species namely Johnius sp. and
Johnius cf carouna. For Johnius sp., it was placed with Johnius cf. carouna through
PCA analyses involving all species PCI, 0.718 and PCII, 0.394 although its look
difference morphologically. Subsequently, PCA analyses only consisted Johnius sp.,
Johnius cf. carouna and Johnius carouna suggested that second anal spine PCI, 0.686
and first ray length PCII, 0.379 were the good characteristics to differentiate among
them. Johnius cf. carouna differs with Johnius carouna by shorter second anal spine
and first anal fin ray lengths; while Johnius sp. have shorter second anal spine
compare with Johnius carouna and longer first anal fin ray length compare with
Johnius cf. carouna.
