“…Although chlorophyll pigment was not measured, the greenish color of the pond water suggested that the particulate matter mainly consisted of phytoplankton community. Chowdhury and Mamun (2006) reported high abundance of Cyanophyceae in two fishponds in Khulna during dry season. Affan et al (2005) reported that chlorophyll a concentration in a pond of central Bangladesh became higher in March (dry season) than the concentration in September (wet season).…”

“…1)). A significant number of natural wetlands and artificial ponds cover the area (Chowdhury and Mamun, 2006). The ponds in the villages are used for many purposes: rural domestic uses including dish washing, laundry, bathing and cooking (Sultana and Crow, 2000), wastewater storage use, agriculture use (paddy fields) especially in Rupsa and Mollahat and fishery use (prawns and fish) in Fakirhat.…”

“…The increase in Z1 was clear during the dry season and suggested an increase in the trophic state in ponds D, A, F and U. Nutrients are generally necessary for paddy and fish production. Nutrients such as cow dung and urea are also added in F ponds to increase fish production in the same area (Chowdhury and Mamun, 2006). Therefore progress of the eutrophication during dry season seems to matter little to A and F ponds.…”

Artificial water storage ponds in the rural area around Khulna and Bagerhat Districts in Bangladesh were surveyed and categorized into domestic use (denoted as D), wastewater storage use (W), agriculture use (A) and fisheries use (F) for the rural ponds and urban domestic use (U: divided into large (Ul) and small groups (Us)). The main survey was carried out during the wet season and a part of the surveyed ponds was also investigated during the dry season. The area and volume of the ponds were large in Ul and F. The transparency was low in the category F, W and U ponds and the SS, TOC were higher in the category F and U ponds than the others. On the other hand the T-N and T-P were higher in category W and U ponds than the others. The size of all the ponds was decreased and the pond water changed more turbid during the dry season caused by increase of particulate matter in the water. The principal component analysis showed that the first component indicating the progress of eutrophication was largely contributed. The water quality of in rural domestic ponds especially during the dry season should be improved.

“…The main foods of rui, catla and catla-rui hybrid were plankton in origin (Mozumder and Naser 2009). Several investigations have been made on the community structure of zooplankton in inland aquatic ecosystems of Bangladesh (Habib et al 1984, Patra and Azadi 1987, Chowdhury et al 1989, Kabir et al 1996, Bhuiyan and Nessa 1998, Hasan et al 2001, Chowdhury and Mamun 2006, Islam 2007, Kabir and Naser 2008, Ahmed et al 2011. It has recently been shown that the aquatic and freeliving pseudopod, Acanthamoeba castellanii is not a predator to V. cholerae O139 rather the bacterium has shown an intracellular compatibility with this host.…”

We studied the coastal zooplankton community structure of six waterbodies of Mathbaria and Bakerganj from January 2008 to June 2009. In total 35 zooplankton species were identified under 26 genera under 20 families under 8 orders from Mathbaria. Among them 6 were protozoans, 24 were rotifers, 3 were copepods, 1 was cladocerans and 1 was ostracods. From Bakergonj a total of 42 zooplankton species were identified under 23 genera under 17 Families under 7 orders. Among them 3 were protozoans, 25 were rotifers, 7 were copepods, 6 were cladocerans and 1 was ostracods. Results showed that abundance of rotifera group from both area was higher in Mathbaria (64.86%) and Bakerganj (60.98%) than other groups while abundance of ostracoda of Bakerganj area was lowest.

“…Homyra & Naz (2005) studied limnology of an artificial lake of Rajshahi. Chowdhury & Mamun (2006) worked on physico-chemical conditions and plankton population of two fish ponds in Khulna. Many researchers worked on the percentage composition, seasonal variation and occurrence of freshwater zooplankton, but little or no information is available on the abundance of zooplankton in culture and non-culture pond in relation to water quality parameters.…”

Zooplankton constitute important food item of many omnivorous and carnivorous fishes. The study was conducted with an aim to study the zooplankton production including physico-chemical parameters with an emphasis to the existing management practices taken by the operators. The study was carried out in a culture and a non-culture pond of Rajshahi University campus was carried out from September, 2004 to February, 2005. Monthly fluctuations of some physico-chemical parameters were noted. The ponds showed alkaline in nature with moderate bicarbonate alkalinity. Diurnal change of water temperature, free CO 2 and dissolved Oxygen were also studied. Four groups of zooplankton were identified, of which copepods (1260 units/l and 973.33 units/l in pond-1 and pond-2 respectively) were most dominant. A total of 9 genera of zooplankton were identified of which Cyclops (68.25% and 60.28% of total copepods) was most abundant in both ponds. Total zooplankton showed positive correlation with pH, carbonate alkalinity (CO 3 ) and bicarbonate alkalinity (HCO 3 ) in both ponds and DO, carbon dioxide (CO 2 ) in pond-1. Present findings indicated that the culture pond showed better result than that of the non-culture pond regarding zooplankton production.
