Environment and fish fauna of the Atrai River: global and local conservation perspective

Abstract
The fish fauna of the Atrai River were studied for a period of two years from January 2011 to December 2012. Sampling was carried out by several fishing nets and traps on fortnight basis. A total of 74 fish species belonging to 27 families and 52 genera were recorded. Cyprinidae was the most dominant family contributing 18 species in 9 genera. Two alien species were found- Hypophthalmichthys molitrix and Hypostomus plecostomus. Thirty locally threatened species (Vulnerable 13.51%, Endangered 18.92% and Critically Endangered 8.11%) were recorded. But, no globally threatened species was found. Relative abundance of majority 36.49% species was rare. Global population trend of 24.32% recorded fish species was Declining. The highest number of species (42) was recorded in the November 2011. Whereas, the lowest the number of fish species (12) recorded in June and August 2011. Very high correlation was found between fish species and physical environmental parameters (air temperature, water temperature, and water transparency). This study concluded that Atrai River could be an excellent place for natural conservation of fish species. Nevertheless, efforts to maintain a sustainable fishing pressure, removal of existing alien species and avoiding further introduction of such species are recommended.

Fish Fauna of the Andharmanik River in Patuakhali, Bangladesh

Abstract
The fish fauna and their season abundance in the Andharmanik River of Patuakhali district have been studied for a period of one year, from March 2011 to February 2012. A total of 53 fish species belonging to 10 orders, 28 families and 47 genera were collected and identified. The most dominant order of fishes was Perciformes (18 species) followed by Siluriformes (12 species) and Clupeiformes (9 species). Maximum 45 species were recorded in November whereas minimum 19 species in May. September was recorded as the peak (availability) month for majority 11 species. May was revealed as the lean season for majority 14 species. Two critically endangered, 3 endangered and 5 vulnerable fish species of Bangladesh were also recorded along with one alien carp species.

A study on aquarium fish business in Jessore district, Bangladesh

Abstract
This study was conducted in Jessore district of south-western Bangladesh with a view to identifying present status of aquarium fish business for a period of six month from September 2012 to February 2013. Only three aquarium shops were recorded and all were located at the heart of Jessore city. Owners of 3 others shops were already closed their business. Only 17 varieties of ornamental fish were recorded to be sold in the surveyed shops belonging to 3 orders- Cypriniformes (52.94%), Perciformes (23.53%) and Siluriformes (23.53%). No fish was found to be sold during winter months i.e. January and February and retailers diverted to other subsidiary business this time. All species were exotic fish and brought from Katabon area of Dhaka city. The highest retail price was found for large silver shark (123.33±40.41 BDT/pair) followed by goldfish (106.67±11.54 BDT/pair) and black moor (105.00±39.05 BDT/pair). Large sucker mouth catfish made the highest profit (38.33±02.89 BDT/pair) to the retails. The study concluded with the following recommendations for the development of aquarium business- production of ornamental fish locally, inclusion of native ornamental species for selling and suitable promotional activities.

An Overview of the traditional rice-prawn-fish farming in Kalia of Narail district, Bangladesh

Abstract
This study was conducted in Narail district, Bangladesh between January and June, 2012; with a view to describing the status of rice- prawn-finfish based aquaculture practices. Average area of plots was 0.55±0.44 ha, of which mean ditch area was 4.35±2.02% of total land. All farmers dry their plots and made renovation prior to start of a new growing season followed by liming and fertilization. No standard stocking density was maintained, prawns were stocked at 15895 PL/ha, whereas fin fishes at 1551 seeds/ha. Commercial feed was applied in all the plots. Production of prawn, stocked and non-stocked finfishes were found 380.34±155.25 kg/ha; 713.65±352.99 kg/ha and 51.73±24.55 kg/ha respectively. Average cost and income for fish culture were 120514.07±36758.35 BDT/ha and 232497.48±76594.80 BDT/ha respectively. Average rice production was 4229.78±856.71 kg/ha. Low growth and high mortality of PL; scarcity, high and uprising price of feeds; and floods were identified as the major problems.

Livelihood of the fishermen in Monirampur Upazila of Jessore district, Bangladesh

Abstract
The study was conducted to assess the livelihood of fishermen in Monirampur Upazila of Jessore district from July to December, 2012. The mean age and fishing experience of fishermen were 35.22±9.67 and 17.9±7.12 years, respectively. Primary occupation for majority fishermen (90%) was fishing. The mean monthly income of the household (HH) was BDT 9470±4806.89. Only 2% fishermen were landless. 4% fishermen had training on fishing/fish culture. 46% fishermen involved in NGOs for loan and savings. 52% fishermen cultivated paddy during boro (summer) season whereas only 18% cultivated paddy during aman (rainy) season. Major protein sources to the HHs (monthly) were- small indigenous species (SIS) (4.60±2.64 kg), non-SIS (6.31±4.18 kg), meat (3.54±1.67 kg), eggs (18.73±22.20 pieces), and milk (11.10±15.54 liter). The major HH expenditures were- food, education, health, furniture, cloths and others. All fishermen were vulnerable to vabadaha, a situation when water logging takes place during monsoon due to lack of sufficient water drainage system.
