This study was carried out to identify the species and morphological characteristics of
family Sciaenidae in Bako, Sarawak. Sixteen (16) species from this area were identified
whereas 8 species were from genus Johnius, 2 species from genus Nibea, 2 species
from genus Panna, and 1 species from genus Bahaba, Chrysochir, Pennahia and
Protonibea respectively. There were 28 parameters measured (morphometric) and
counted (meristic). The results were then analysed by using Principle Component
Analysis (PCA) in order to obtain the most significant parameter to distinguish all the
species. There were two pairs of species that were hard to distinguish, which were
Nibea soldado and Nibea cf. soldado; Johnius carouna and Johnius cf. carouna. The
most significant parameters to distinguish the first pair were second anal spine length
(0.876) and eye diameter (0.501) while the most significant parameter for the latter
pair were preanal length (0.508) and second base dorsal fin (0.460).
