| Abstract | ||||
| The Corbiculidae exhibits a great variations in shell-shapes and colours that make the discrimination of the bivalves of the genus in difficult, Corbicula jluminea and C. ftunrinalis. This study was carried out to solve this conflict. The substratum of the investigated clams is sand-gravel or sand-gravel-muddy and its water is transparent and calm. Moreover, the morphological characters (shapes and colours) of the shells were thoroughly investigated and sorted into three groups according to shapes and colours.Electrophoresis SDS= polyacry (amide electrophoresis gel were made on the three sorted groups and juveniles that show no differences in protein patterns as well as their scans profiles. It was concluded that all ecomorphs are belonging to one species; C. Jluminea that collected from irrigation canal system of River Nile, Egypt. | ||||
