El-Max fish farm is one of the most important natural fish farm in Alexandria which is suffering from die-off of large amounts of fish. Facing this problem we must deal with the estimation of the quality of the farm raring unit environment (ponds). Analysis of samples using the Bray - Curtis similarity coefficient test yielded that, the input and El-Khandac were similar at (97%), while the eight ponds were classified at different level of similarity as follows: pond1 (B1) and pond7 (B7) were similar at (86%), B2 and B3 were similar at (90%), B14, B10 and B9 were similar at (93%), where as B11 is singly separated at (83%). Moreover, results indicate that distribution of the different bacterial groups was affected with one or more chemical parameters such as... |

During the course of 7 years (1998-2004), five field trips were performed annually in January, march, May, July and September. 1400 water samples (200 samples/year) were collected from 40 coastal sites covering the recreational areas as well as different hot spots and some protectorate areas. Hydrochemical parameters including temperature, salinity, pH and dissolved oxygen as well as bacteriological parameters including total coliforms, E. coli and fecal streptococci were investigated. Inverse relationships were observed between salinity and each of total coliforms (TC) (r = -0.149, P ≤ 0.05) and E. coli (EC) (r = -0.147, P ≤ 0.05) in the Suez Gulf, whereas in Red Sea there was an inverse relationship between temperature and fecal streptococci (FS) (r =... |

Spatial and temporal variability in the saprophytic (SB) and salt tolerant saprophytic (STSB) bacterial counts as well as total coliforms (TC), E. coli (EC) and fecal streptococci (FS) were investigated in the Egyptian surface coastal waters of Aqaba and Suez Gulfs as well as Red Sea. A total of 200 samples collected from 40 sites during January, March, May, July and September 2002 were investigated. Hydrographical parameters including water temperature (oC), salinity (S%o), dissolved oxygen (DO) and pH were also measured. According to the European and Egyptian current standards, out of 200 samples analyzed during 2002, 183 samples (91.5%) were accepted for marine recreational purposes. The obtained results indicated that water quality of the investigated... |
