Abstract

The study about morphometric of tapah fish (Wallago leeri Bleeker, 1851) from Siak River
and Kandis River had been done. The purpose of this study was to compare tapah fish from
Siak River and Kandis River using 26 morphometric characters. This study was carried out

tapah fish from Kandis River. The results indicated the differences of morphometric
characters between tapah fish from Siak River and Kandis River. Linear regression analysis
showed that tapah fish from Siak River and Kandis River have very weak to very strong
