The study was conducted to observe the status of fisheries resource of Tanguar haor, one of the large wetland in the north eastern part of Bangladesh. For this purpose the whole study was completed in two parts: interviewing with local people and analyzing the water quality. Indiscriminate harvesting of mother fishes, use of agrochemicals, sedimentation on haor basin and habitat destruction were found as major causes of fisheries resources degradation in the study area. Most of the water quality parameters were found good which were within the standard level set by Government of Bangladesh for fisheries. However, EC and TDS were found higher than the recommended level for fish production.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22048 J. Environ. Sci. & Natural Resources, 6(1): 103-106 2013

The Status

Wheat crop in the North Eastern Plain Zone (IGP) of India, is the part of one of the largest agricultural production systems viz., rice-wheat rotation, occupying more than 11 million ha. The yield potential of wheat in the North Eastern Plains Zone of India is about 4.5 tons per hectare but generally, farmers realize a yield of only 2.2 tons per hectare. Seed replacement rate of wheat in different eastern states has also been quite low. A study was initiated at the Indian Agricultural Research Institute, Regional Station, Pusa (Samastipur) in 2014-15 to evaluate germination and seedling growth parameters of wheat grown from seeds of varying size. Experiments were conducted on quality evaluation of different seed grades of bread wheat available to the farmers for sowing to study the status of quality vis-à-vis size grading and what is its effect on germination and early dry matter gain with two objectives of this investigation. First, to assess the physical quality of wheat seed available to farmers in North Eastern Plains Zone (which is also known as lower Gangetic plains) in terms of seed size and seed grading and second, to determine the relationships between seed size on one hand and germination and seedling developmental and biomass traits on the other. This paper presents the results of an enquiry into the status vis-à-vis seed grading, of seed lots of wheat which are available to farmers for sowing with the aim of estimating the extent to which the quality of wheat seed can be improved by merely grading and to establish the relation between seed size and crop establishment. From the results of this study, it can be inferred that 67.97% of area in North eastern plains zone (NEPZ) of India is sown with seed either saved by farmers or obtained locally. Use of sub-standard seed may be counted prime among many factors responsible for low productivity of wheat in lower Gangetic plains. Only seeds from authentic sources were found to be properly graded. It was also observed that wheat seed supplied by registered companies are as good in terms of grading and germination as seeds supplied by government organizations including national and state seed corporations. Graded seeds not only have higher germination ability but also higher seedling vigour in terms of dry matter gain in seedlings during early vegetative growth phase.

This study evaluates the water quality for the Canal of Shatt Al-Basrah, located in Basrah province, Iraq. The Shatt Al-Basrah Canal used to connect the waterway from Al-Hammar marshes in the north of Basrah province, to Khor Al-Zubair port in the south of the province. Nine physicochemical water quality parameters have been measured and analyzed for calculating the water pollution index (WPI) in the Canal. These parameters, which were used in developing the WPI, included: Potential of Hydrogen (pH), Nitrate (NO3-), Calcium (Ca2+), Total Alkalinity (TA.), Electrical Conductivity (EC), Sodium (Na+), Total Dissolved Solids (TDS), Sulfate (SO42-), Phosphate (PO43-), Dissolved Oxygen (DO), Total Hardness (TH), Chloride (Cl-), Magnesium (Mg2+), and Potassium (K+). The aim of this paper is to analyze and assess the water pollution of the Shatt Al-Basrah Canal in the year 2014, making use of the WPI method.  The annual WPI mean value during the study period was more than the safe value; therefore, the water quality of the Canal ranged from impure (type V) to the heavily impure (type VI) and hence definitely regarded as unsuitable for drinking uses. Consequently, there is a need that is immediate to take some measures to stop the pollution and enhance the water quality of the Canalas a component that is integral tothe environment in Basrah province. In Basrahprovince, the disposal of wastewater in the Shatt Al-Basrah Canal is big maintenance difficulty of the Canal water quality.

The study was conducted to determine the status of physico-chemical parameters of the Brahmaputra river water in Sherpur district and also to assess the monthly variation of the river water. To perform the study the samples were collected from five different stations during the period of December 2013 to May 2014. Various water quality parameters such as transparency, temperature, electrical conductivity (EC), total dissolved solids (TDS), pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), hardness and alkalinity were examined. The study revealed that a slightly variation in water quality at different stations of the river. The mean value of transparency (42.21 cm), temperature (23.38oC), EC (351.12 ?s/cm), TDS (178.54 mg/l), pH (7.75), DO (4.47 mg/l), BOD (1.02 mg/l), hardness (82.36 mg/l) and alkalinity (98.63 mg/l) showed that the present status of the Brahmaputra river water is suitable for all aquatic lives, domestic and agricultural uses. Although the overall status of the river water quality is suitable, degradation was detected in few points which might be due to anthropogenic activities, especially the direct discharge of domestic effluents into river. Thus, necessary initiatives should be taken against such anthropogenic activities to maintain the overall water quality of the Brahmaputra river for its sustainable use.Bangladesh J. Sci.
