Ecological Studies of the Macrobenthic Fauna of Ashtoum El-Gamil Protectorate, Port Said

Abstract

Macrobenthic invertebrates samples were collected seasonally from five stations, selected according to their environmental ecosystem (marine, brackish and fresh) in Ashtoum El-Gamil protected area. This protectorate is located in the north western part of Lake Manzala. Macrobenthic community was found including thirty five species belonging to four groups. Of these species, 3 Polychaetes, 19 gastropods, 7 bivalves and 6 crustacean. Some of them are freshwater species and others are marine. Gastropods were dominated other groups, the highest average standing crop was recorded in station V. Macrobenthic fauna reached its maximum average value in spring in the whole area, while winter was the minimum productive season. Environmental parameter and nature of the sediment were important factors affecting distribution and abundance of macro benthic invertebrates. But It has been found that the percentage of the live organisms which have been monitored do not exceed 7% of total organisms.

“…In addition, the Rosetta branch of the Nile River at Kafr Elzayat city receives industrial effluents from Kafr El-Zayat Pesticides and Chemicals KZ, Salt, and Soda companies, which are discharged directly at the east bank of the branch [ 32 ]. From the far northeast to the northwest of the Delta, many authors have reported the marine shift in the salinity of the Nile water in Port Said, El-Behaira, and Alexandria provinces during the spring and summer seasons, respectively [ 13 , 33 , 34 , 35 ]. This salinity shift is a result of climate change, rising sea levels caused by global warming, and the intrusion of saltwater from the Mediterranean Sea downstream into the Nile.…”
