  Background and Objective: Fisheries sector plays a significant role in the economy of the country. The marketing system with good management and environment is pre-requisite for sustainable economic structure. The present study was executed to know the existing drawbacks and potentials of Kazir Dewari Bazar. Along with some recommendations was extracted from the study area to improve the existing Bazar condition. Materials and Methods: The survey was conducted in 2017 for collecting the field data by using different methods (e.g., structured interview, Focus Group Discussion and Key informant interview etc.). Results: The Bazar is very important to the local community but with some common problems. Intermediaries had great influence on the fish seller income (p<0.05). The environment of the Bazar was not up to the mark. The market condition was not hygienic for handling fish due to lack of proper physical facilities. This unhygienic environment causes various health problems to sellers and buyers. Marine fishes are the common fish in the Bazar. Importantly, the fishermen and retailers got limited profits while stockists (Aratdars) received high profits from selling fish. Consequently, the financial condition of the fishing community and the retailers were not good enough. Conclusion: Physical facilities like processing, packaging, sanitation, water supply, drainage, cleaning, washing, maintenance and other necessary measures were not sufficient in the Bazar. This situation can be improved by proper management of the Bazar committee and strict monitoring from the government.

  Background and Objective: Fisheries sector play important role in the economy. Diversity status is needed to conserve the fish resources of the haor region. The present study was conducted to assess fish diversity of the Kalai beel and Naoli beel of Karimganj Upazila in Kishoreganj district, Bangladesh. Materials and Methods: Fish samples were collected from the fishermen and local fish market for taxonomic study from December, 2014-November, 2015. Morphometric and meristic characteristics were identified through direct observation and further identification was done following different books. Results: A total of 46 fish species were identified during the study under 17 families. Among 46 fish species, 15 were found belong to Cyprinidae family followed by Bagaridae (4), Channidae (4), Schilbeidae (3), Mastacembelidae (3), Centropomidae (3), Siluridae (2), Anabantidae (2), Palaemonidae (2) and others (8). During the study period, 22 fish species were marked as abundant species, 15 species were marked as rare and 9 species were found as common species. Conclusion: Ecologically, economically and socially haors are playing essential role with its diversified fish resources. Haor fisheries have great impact on the livelihood of the fishermen and provide nutrition to general people. However, the fish diversity is being threatened by anthropogenic activities. Present study emphasized on the conservation of the fish as it is undergone gradual decrease.

  Background and Objective: Watershed is an area of land that comprises a set of watercourses and rivers that all drain into a single larger water body (River). Watersheds are important since the surface water and storm water runoff within a watershed eventually drain to other bodies of water. During increasing and executing water quality protection and restoration actions, it is needed to consider these downstream impacts. The present study was conducted to explore the available major water sources of the Halda river. Materials and Methods: Data were collected through extensive field survey and structured questionnaire survey from November, 2011-September, 2012. Data were analyzed by one-way analysis of variance (ANOVA) using SPSS. Results: A total of 34 watersheds of the Halda river were recorded. Out of them major seven watershed areas namely: Manikchari Khal, Dhurang Khal, Sattar Khal, Fatikchari Khal, Harualchari Khal, Baromasi Khal, Mondakini Khal were selected for the study. The mean width of the above mentioned Khals were 33.75, 37, 51.5, 19.5, 15, 12.5 and 19 m, respectively. The mean depth of these khals were 5.75, 8.5, 10.5, 5.5, 7, 4 and 6 m, respectively and the approximate length of these khals were about 25, 56, 45, 28, 19, 17 and 18 km, respectively. Noteworthy difference was found among the watersheds in terms of mean depth, mean width and mean length (p<0.05). Conclusion: Discharged water of the watershed directly covers a large area through different khals of the river, indispensable resource for aquatic organisms and human being. Therefore, it is essential to conserve these watershed areas from haphazard pollution for sustainable ecosystem health management and meaningful development of the country.
