| Water and phytoplankton samples were sampled on a seasonally basis, from autumn 2002 to summer 2003 at five stations located in Bitter Lakes and four at Temsah Lake. A total of 116 taxa were identified, among which 72 taxa of diatoms, 16 dinoflagellates, 14 chlorphytes, 11 cyanophytes, two euglenophytes and one silicoflagellate species. Bitter Lakes were more diversified than Temsah Lake, although the highest population density was recorded at Temsah Lake. A total of 108 taxa were identified in Bitter Lakes among which 68 taxa of diatoms, 15 dinoflagellates, 11 chlorophytes, 11 cyanophytes two euglenophytes and one silicoflagellate species, while 102 taxa were identified among which 60 taxa of diatoms, 14 dinoflagellates, 14 chlorophytes, 11 cyanophytes,... |

| Diel vertical migration of different zooplankton groups in Dekhaila Harbor was studied monthly from May 2003 to April 2004. Generally, more groups were found in the surface layer (0-10 m.) than the deeper one (10-20 m.). Some zooplankton groups undergo significant vertical migration at certain time of the year, others showed no clear differences in distribution patterns and exhibited no directed movement patterns. Some species stayed a part of the day within certain layer of the water column, others were randomly dispersed in the whole water column during different hours. Responses appear to depend also on the life stages of each zooplankton group, as well as other ecological conditions such as temperature, light and amount of food. Population budget... |
