Cultivation of () using confectionary wastes for aquaculture feeding.

The microalga biomass production from confectionary effluent is a possible solution for the urgent need for a live food in aquaculture. () was the dominant alga in effluent of "Biscomisr a confectionary factory", in Alexandria-Egypt. Therefore, it was isolated from the effluent samples and used throughout the study.

Studies on spatio-temporal dynamics of phytoplankton in El-Umum drain in west of Alexandria, Egypt.

Phytoplankton was assessed quantitatively and qualitatively in regard to their abundance in the northern part of El-Umum drain, west of Alexandria at four stations to study the spatial, temporal, dominance and abundance of the phytoplankton community. The samples were collected monthly from April 2003 to April 2004. Atotal of 152 phytoplankton taxa were identified belonging to Bacillariophyceae (60), Chlorophyceae (46), Cyanophyceae (20), Euglenophyceae (17) and Dinophyceae (9).
