Khanom, T Khatun, M.A.S. Jewel*, M.D. Hossain and M.M. Rahman Department of Fisheries, University of Rajshahi, Rajshahi 6205, Bangladesh Abstract: The study was conducted to investigate the abundance and present status of fish biodiversity in the Shiba river at Tanore Upazila of Rajshahi district, Bangladesh. The study was conducted from November, 2016 to February, 2017. A total of 30 species of fishes were recorded belonging to nine orders, 15 families and 26 genera. Cypriniformes and Siluriformes were the most diversified groups in terms of species. Among 30 species, nine species under the order Cypriniformes, nine species of Siluriformes, five species of Perciformes, two species of Channiformes, two species of Mastacembeliformes, one species of Beloniformes, one species of Clupeiformes, one species of Osteoglossiformes and one species of Decapoda, Crustacea were found. Machrobrachium lamarrei of the family Palaemonidae under Decapoda order was the most dominant species contributing 26.29% of the total catch. In the Shiba river only 6.65% threatened fish species were found, and among them 1.57% were endangered and 4.96% were vulnerable. The mean values of Shannon-Weaver diversity (H), Margalef’s richness (D) and Pielou’s (e) evenness were found as 1.86, 2.22 and 0.74, respectively. Relationship between Shannon-Weaver diversity index (H) and pollution indicates the river as light to moderate polluted.

Regular bi-monthly sampling was conducted from January, 2011 to December, 2012 by using different nets with the help of artisanal fishermen. Fishes were also collected from local fish markets. We have collected 66 fish species belonging to 9 orders, 22 families and 38 genera. Order Cypriniformes was the dominant group with 26 species followed by Siluriformes and Mugiliformes each with 11 species, Perciformes with 7 species, Anguilliformes, Cyprinodontiformes and Mastacembeliformes each with 3 species and Osteoglossiformes and Elopiformes each with 1 species. Out of 66 species, 3 species are near threatened, 3 vulnerable, 4 at lower risk near threatened, 1 at lower risk least concern, 37 least concern, 15 not evaluated and for 3 species data is deficient as per IUCN (2013) Red List category. According to CAMP (1998) conservation status, 4 species are endangered, 13 vulnerable, 24 at lower risk near threatened, 2 at lower risk least concern, 22 not evaluated and for 1 species data is deficient.

Ferdoushi Department of Fisheries Management, Hajee Mohammad Danesh Science and Technology University Abstract: Among different water quality parameters dissolved oxygen, transparency, pH, PO4-P and depth varied significantly among the sampling sites. The pH value in the present investigation remained a buffer condition (6.50- 7.90). Dissolved oxygen was ranges from 3.80 to 11.60 mg/l throughout the study periods. PO4-P concentration was observed highest (0.30 mg/l) in sampling site 2. On the basis of physical, chemical aspects sampling site 3 and sampling site 5 (situated in gosaipur and chandandoho) found in better condition in terms of limnological aspects. However, it could be concluded that Dhepa River will play important role in riverine fisheries and for further fisheries management.

Fish species diversity data were collected from fishers using Fish species diversity participatory rural appraisal tools and the change in the fish species diversity was determined using Shannon- Fishers Wiener, Margalef's Richness and Pielou's Evenness indices. Principal component analysis (PCA) was conducted Principal component analysis with a dataset of 150 fishers survey to characterize the major factors responsible for the reduction of fish species Climate change fi Anthropogenic activity diversity. Out of 63 sh species, 83% of them were under the available category in 2008 which decreased to 51% in 2018. Fish species diversity indices for all 12 taxonomic orders in 2008 declined remarkably in 2018. The first PCA (climatic change) responsible for the reduced fish species diversity explained 24.05% of the variance and consisted of erratic rainfall (positive correlation coefficient 0.680), heavy rainfall (À0.544), temperature fluctu- ation (0.561), and beel siltation (0.503). The second PCA was anthropogenic activity, including the use of harmful fishing gear (0.702), application of urea to harvest fish (0.673), drying beels annually (0.531), and overfishing (0.513).

(August 2007) Stephanie Kimberly Rice, B.S., The University of Mississippi Co-Chairs of Advisory Committee: Dr. Beth L. Mullenbach Dr. Wilford D. Gardner An examination of suspended sediment concentrations throughout the Ganges- Brahmaputra River System was conducted to assess the spatial variability of river sediment in the world’s largest sediment dispersal system. During the high-discharge monsoon season, suspended sediment concentrations vary widely throughout different geomorphological classes of rivers (main river channels, tributaries, and distributaries). An analysis of the sediment loads in these classes indicates that 7% of the suspended load in the system is diverted from the Ganges and Ganges-Brahmaputra rivers into southern distributaries. Suspended sediment concentrations are also used to calculate annual suspended sediment loads of the main river channels. These calculations show that the Ganges carries 262 million tons/year and the Brahmaputra carries 387 million tons/year.

Hundred fishermen were surveyed randomly with a structured questionnaire. The livelihood status of fishermen was studied in terms of age, family, occupation, education, housing and health condition, credit and income. It was found that most of the fishermen were belonged to the age groups of 20-35 years (50%) represented by 85% Muslims. Majority of them (62%) lived in joint family and average household size was 6-7 people. Educational status revealed that 66% were illiterate. Fishermen houses were found to be of two types namely semi-constructed and unconstructed and among them 77% houses were connected with electricity. About 85% fishermen were landless represented by 95% rearing livestock. Regarding health and sanitation 85% fishermen used sanitary latrines. About 83% fishermen were solely depends on fishing and annual income of 50% fishermen was 50,000 to 60,000 TK.
