“…Meshram, (2014) [28] opined that maximum density of copepod fauna in summer may be due to availability of plenty live food and competition with other species. However, Bhuiyan, et al (2008) [8] stated that the effect of over fishing might be the probable reason for maximum density of copepod fauna during summer season. Lowest density of copepod fauna during monsoon is the dilution effect and as such some physico-chemical factors like lower water temperature, pH, salinity and TDS are not in favour for the growth and survivability of copepod fauna (Maruthanayagam 2008 [36,21] .…”

“…On the contrary, the optimal numerical abundance of copepod fauna was observed in the temperature range between 29-33 o C. Mesocyclops leuckarti, the super dominant copepod species reached a peak population at about 31 o C and its population was completely disappeared at a temperature below 14 o C. The present observation showed that copepod fauna were dominant in warmer period of the year. Bhuiyan, et al (2008) [8] emphasized the role of temperature on crustacean densities. Bhuiyan, et al (2008) [8] reported that temperature on one hand, acting directly for accelerating the growth rates of crustacean zooplankton which in turn increases the population densities of crustaceans and on other hand, it hastens the growth of phytoplankton population which serves as live food for crustacean zooplankton.…”

Diurnal vertical migration of four genera of cladocerans, namely Diaphanosoma sp., Daphnia sp., Moina sp. and Bosmina sp., during March to December, 2007 showed that the number of Diaphanosoma sp. was 501 units/1 in the surface layers, 172 units/l in the middle layers and 190 units/l in the bottom layers. The yearly number of Daphnia sp. in surface, middle and bottom layerss was 362 units/l, 46 units/l and 189 units/l respectively. In surface, bottom and middle layers, the number of Moina sp. was 159, 71 and 32 uiiits/l, respectively. Bosmina sp. was 78 units/l in surface, 31 units/l in the middle and 33 units/l in the bottom layers. The number of Diaphanosoma sp., Daphnia sp., Moina sp., Bosmina sp., were 455, 149, 259 and 358 units/l, respectively in the morning, 63, 176, 142, 43 units/l at noon and 107, 55, 28, 59 units/l, respectively in the evening. Throughout the study period the cladocerans were always abundant near the surface during morning and evening. Among the factors responsible for the diurnal movement of cadoceran, light played the most important factor. The relationship between the physico-chemical factors and the cladoceran occurrence in the pond was also explored.

This study aims to investigate the phytoplankton dynamics (distribution, composition) and their relation to water quality parameter in Ismailia canal and Abbassa fish farm (inlet, outlet and the fish ponds).The study was carried out from April, 2014 to May, 2015. Physical, chemical parameters and phytoplankton estimation were measured in situ and laboratory. The results showed that, the physico-chemical parameters of water were significantly varied among different seasons and the studied sites. Phytoplankton communities are represented by eight phyla namely; Chlorophyta, Cyanophyta, Euglenophyta, Bacillariophyta, Chrysophyta, Dinophyta, Cryptophyta and Xanthophyta. Their major number (22724 Org./ml) was detected at the fishponds (site C), while their minor number (9374 Org./ml) was detected at the main feeder (MF), (site A). Chlorophyceae was the predominant class at all studied sites except at (MF) where; Bacillariophyceae occupied the first predominant position. Results demonstrated that occurrence of 247 taxa of phytoplankton at (MF), 273 taxa at (inlet), 304 taxa at fishponds and 292 taxa at outlet. Also, Shannon and Weaver diversity index (H -) was studied and the results showed that the mean range of the phytoplankton diversity index (H -) was low (< 2.0) at all the studied sites and this is indication of moderate pollution. It is concluded that, both seasonal variations and physico-chemical parameters of water have great impact on phytoplankton dynamics and its biological diversity.
