“…Similar results from other study [33] on faunal composition, seasonal abundance of polychaete (ind./ m 2 ), species richness and species biodiversity (Swandwip, Hatiya, Bhola, Barisal and Chandpur) of Bangladesh revealed that Polychaetes was the most dominant among the macrobenthic groups constituted 56.72% of the total macrobenthos. However, results from the present study on microbenthic species composition was a little bit higher than that of the results postulated from Abu Hena on Bakhlali river estuary (Polychaeta, 9.966-30.31%; Oligochaeta, 3.68-30.31%; Crustacea, 0.02-58.40%; Bivalvia, 1.40-82.09% and Gastropoda, 0.08-4.25% and similar to the results of Asadujjaman [14,15,18,34].…”

“…It was the highest at Swandwip during post monsoon and lowest at Bhola during monsoon in Bangladesh. Abu Hena [15] also identified that the Shannon diversity index ranged from 0.65-1.04 among the sampling stations at the Bakkhali River Estuary, Cox's Bazar.…”

“…However, there is scare study on macrobenthos abundance and distribution in the Bakkhali River. One study assessed the macrobenthos composition in the Bakkhali river and reported five major macrobenthos taxa in the river (Hena et al, 2012) that it was different from the present study. Macrobenthos abundance and distribution changes over the course of time as physico-chemical parameters might alter the marobenthos distribution.…”

The study aimed to assess the macrobenthos abundance and distribution from the Bakkhali River, East Coast of Bangladesh. Macrobenthic and water samples were collected from the upper, middle and lower part of the river during post-monsoon. Several indices were used to find macrobenthos abundance and distribution and their correlation with water parameters were also assessed. Present study identified a total of 628 macrobenthos individuals representing 10 major taxa at three stations where 9 taxa were reported in both upper and middle parts whereas only 7 taxa were observed at lower stream of the river. The highest abundance of macrobenthos (301.04 indivs/m2) was recorded at the lower stream and the lowest abundance (166.3 indivs/m2) was found at the upper part of the river. Macrobenthos distribution showed that the number of Oligochaetes was higher (220 indivs) followed by Nemertinas (169 indivs) and Polychaetes (145 indivs). Study findings reveal that macrobenthos abundance and distribution were comparatively higher at the lower stream than the upper and middle part because of higher level of pollution and sendimentation rate that might influence the macrobenthos abundance and diversity in the upper and middle part. The study also found macrobenthos abundance was proportionally increased with increasing salinity and pH. However, macrobenthos abundance was decreased with increasing temperature. Simpson index (D) was the highest (0.32) at middle and lower part and the lowest (0.23) was in the upper part. Shannon-wiener index (H) was also higher (1.68) at the upper part. Both the indices showed higher diversity at the upper part because of having maximum taxa in the station. Based on the H value, this study reported that Bakkhali River was moderately polluted since H value was in the range of 1.44 to 1.68. These might be because of anthropogenic sources of pollution in the vicinity of the river. This study suggests to take proper management strategies to control aquatic pollution and conserve aquatic biodiversity.

“…It is highly productive in terms of nutrient input from different sources that promotes other living resources (Kamal and Khan, 2009). However, continuous environmental disturbance like sedimentation, urban runoff and pollution are badly affecting the ecosystem of this estuary (Hena et al, 2012). Bakkhali river is the main discharge point of the city waste of Cox's Bazar.…”

“…Waste discharge and chemical spills are mainly connected with boat repair industry that represents an additional source of pollutants to the water and sediments. However, several studies have been conducted on pollution and other entities of Bakkhali river estuary (Siddique et al, 2012;Rashed-Un-Nabi et al, 2011;Hena et al, 2012). But information regarding bacterial pollution of this estuarine system is lacking.…”

The present study aims to investigate the isolation of human pathogenic bacteria (Escherichia coli, Salmonella spp. Shigella spp. and Vibrio spp.) and in gills, intestines, skin of fishes of Bakkhali River Estuary, Cox's Bazar. A total of 50 fish species (25 of Pomadasys hasta and 25 of Glossogobius giuris) were collected from two sampling stations namely Station-1 (Rumalia Chara) and Station-2 (Kusturi Ghat). Bacterial analyses were made by standard methods. Total heterotrophic bacterial load of the isolates was found to be lower than the recommended public health and standard. However, the highest pathogenic bacterial (E. coli, Salmonella spp. Shigella spp. and Vibrio spp.) count at Station-2 might be due to the contamination of municipal and domestic wastes and discharges from small industries that constitute the main pollution source of this estuarine river. Skin was found to be the most preferred organs for higher bacterial load compared to intestine and lower count was recorded in gills. Further research on the microbial quality assessment should be undertaken to prevent pollution of this river estuary.
