“…Average air temperature was little bit different among the three sites but average air temperature in winter was varied greatly compare to summer and monsoon. Rakiba and Ferdoushi (2013) found average air temperature at six different sites in Dhepa River, Dinajpur ranged between 30.33 ± 4.16 to 26.93 ± 4.87 o C which is almost similar to the present findings.…”

This investigation was undertaken to evaluate some physico-chemical parameter of water of the trans-boundary Haora River in Brahmanbaria during October 2018 to September 2019 from three different sites. The study revealed that air temperature at three different sites ranged 13 – 38 °C while the water temperature was 11 – 32 °C. Transparency of water varied from 18 – 55 cm Secchi depth and became more turbid during monsoon. The average values of pH and dissolved oxygen (DO) both in sites and seasons were within the standard limits for aquatic organisms. Total dissolved solids (TDS) were found between 77 and 352 mg/L and varied greatly in seasons. Electric conductivity (EC) was ranged 135 to 650 μS/cm. On the other hand, maximum and minimum hardness of water were recorded as 322 mg/L and 118 mg/L respectively and become lowest in monsoon. The rainy season bear high torrential water which brought huge amount of different types of garbage through the water flow from the Indian part. Most of the garbage are of floating and submerged type as plastic containers, bottles, polybags, cans, etc along with natural debris. During the study period highest (172 kg) and lowest (113 kg) plastic garbage were collected in May and July respectively. This foreign garbage may impair the normal healthiness of the river ecology.

“…However, significant differences (P < 0.05) were observed in hydrological parameters among habitat and season similar to Grimaldo et al (2012). Besides, values of water quality parameters from these rivers were within the limits reported by Rakiba and Ferdoushi (2013) due to close ecological area. Fish assemblage and structure are mainly affected by seasonal changes along with ecological factors in estuaries (Loneragan and Potter, 1990;Young and Potter, 2003).…”

Stream fish assemblage and their association with major ecological factors were spatiotemporally conducted from January to December 2015 at the Tangon and Kulik Rivers of Thakurgaon district in Bangladesh. A total of 6,561 specimens belonging to 53 fish species dominated (> 4.86%) by Aspidoparia jaya, Pethia ticto, Puntius sophore, Channa punctatus and Canthophrys gongota both in rivers and seasons. Significant differences (P<0.05) were spatiotemporally observed in the values of diversity indices between two rivers. Spatial and temporal patterns influenced species copiousness and richness that higher in winter season due to little water echelon. Fish communities were differed between rivers (R = 0.46, P<0.01) and seasons (R = 0.21, P<0.01) stressing as 0.24 and dividing into two clusters at a value of 87.65% union. Canonical Correspondence Analysis (CCA) specified that water depth, water temperature and transparency were key environmental factors affecting fish assembly, abundance and distribution. Therefore, advanced plans and management strategies should be taken to save threatened fishes at low water depth during dry and winter seasons than others.

“…The maximum productivity may be obtained when the physical and chemical parameters are at the optimum level. Therefore, water quality has paramount importance in ecosystem productivity and their sustainable use (Rakiba and Ferdusi, 2013).…”

This article is based on a study that was conducted to investigate the physicochemical properties of water in Gowain river at pre-monsoon (February to May), monsoon (June to September) and post-monsoon (October to January) seasons and to determine the relationships between water quality parameters. The water samples were collected from five different sampling stations of Gowain river and analyzed in the laboratory of Department of Environmental Science and Resource Management, Mawlana Bhashani Science and Technology University, Bangladesh. The results also showed that most of the water quality parameters were suitable for aquatic organisms as well as fish. However, runoff from upstream and waste generated from anthropogenic sources could be the main causes of degradation of water quality and aquatic organisms.
