Fish diversity in Lake Nubia in relation to water level
Author(s): Zuheir Nour El Dayem Mahmoud
Abstract: Lake Nubia came into existence as a result of construction of Aswan High Dam which began in 1960 in Egypt. The important features which largely affected fish diversity in Lake Nubia were related to construction work of the dam and the gradual transformation of the water ecosystem from riverain to lacustrine condition. Some riverain fish species such as
Heterotis niloticus and
Heterobranchus biodorsalis and dwarf fish species such as
Garra dembeensis (=vineinguerre),
Andersonia leptura and
Eleotris nanus disappeared from the lake. Disappearance was related to change in water level at pre-impoundment, during impoundment and impoundment phases of damming, water characteristics and fish behaviour. Significant correlation (
p<0.05) was found between water level and fish species disappearance.
