| description | African catfish (Clarias gariepinus) was introduced into Malaysia for aquaculture purposes.
They often used to produce a hybrid with indigenous catfish (C. batrachus, C. macrocephalus)
due to their rapid growth rate. There are difficulties in differentiating these three species in
their morphology. An experimental study was conducted to identify morphometric
characteristics between these three species. Specimens of each species (C. gariepinus, C.
batrachus and C. macrocephalus) were collected and analysed in term of their morphological
differences. Seventeen characters have been used for conventional morphometric
measurements. Truss morphometric characters for the body consist of 36 characters. Five
meristic characters were counted. All data were converted into a ratio and undergo
Discriminant Function Analysis. Meristic data also tested by non-parametric Kruskal-Wallis.
All analysis were using SPSS 20V. Conventional morphometrics suggested three characters
(Head Widht, Anal Fin Base Lenght and Outer mandibular barbell length) to differentiate the
three species. Meristic characters showed significant differences in dorsal fin rays, anal fin
rays and caudal fin rays. Conventional and truss agreed on similar morphological
characteristics in species identification. Meristic counting can be used as additional
characteristics in identifying these three species. |
