Abstract

Hard plates covering fish body or scales, do not only serve as external protection, but are also important as one of the tools for species identification. This study was designed to recognise morphological characters of fish scales that can be used for identification and to comprehend the inter-specific variations of scales from different species by using selected indices from scale measurements; L1/1, L2/L, L1/L2, and W/L. Sixteen species of common freshwater fishes were sampled from a few localities in Peninsular Malaysia. Examinations were based on photographs to determine the scale morphologies. Basic distinguishable characteristics that were identified are type of scale, the overall shape, the position and shape of the focus, distribution of radii, and the circuli appearance. It was found that scale type and radii arrangement at the anterior field are two significant morphological features that could distinguish between Cyprinidae and other families. Main characters used to identify scales at species level are radii cover, structure of inter radial tongue, and radii arrangement. Meanwhile, multiple comparison tests to reveal inter-specific variations suggested that there are significant differences among 16 species of common freshwater fishes studied. Two indices were found to be suitable to highlight the significant differences (P<0.05) for all species which are index L1/L2 and index W/L. For all indices, species that showed significantly different with most of other species are Osteochilus vittatus, Pristolepis fasciata, Rasbora sumatrana, and Labeo rohita. The scales of Osteochilus vittatus showed significant values with most of other species in more than one index; index L1/L and index L2/L. The distinctive morphological character that distinguished it from other Cyprinidae species is having clearly formed serrations in the middle of the inter-radial tongue at the anterior region.
