components with the development of the lake. Anon (1979)
studied the geographical distribution of benthic organisms
through Aswan High Dam including Lake Nasser. Latif
et al. (1979) studied the distribution of benthic fauna of Lake
Nasser. Elewa (1987) surveyed the benthic fauna of the lake.
Iskaros (1988) studied the seasonal variations of bottom fauna
in Lake Nasser and adjacent water. Fishar (1995) studied the
bottom fauna along the main channel of Lake Nasser.
Ibrahim and Mageed (2005) recorded a dominance of oligochaets
and arthropods (especially, Insecta), in addition to
few molluscs in the lake. Iskaros and El Dardir (2010) studied
the factor affecting the distribution and abundance of bottom
fauna in Lake Nasser. Abdel Gawad et al. (2014) carried out a
review on macrobenthic fauna in Lake Nasser. The main
objective of this study is to investigate the diversity and spatio-
temporal distribution of macroinvertebrate assemblages.
