Harvesting Giant Freshwater Prawn, Golda (Macrobrachium rosenbergii de Man 1879) in the Sundarnbans mangrove forest plays an important role in the economy of the country as well as the livelihood of local community. The study focused the economic assessment of small-scale artisanal Golda fishery. Overall the Hookline gear showed the best performance in terms of economic return. However, it was found to withstand a shock from 20% decrease in market prices or 30% fall in catch rate in terms of Return on investment, payback period and Benefit-cost ratio. Operating cost and fixed cost for Hookline fishery was the lowest and Khathijal was the highest. No significant variation (P<0.05) observed in the mean catch rate per trip boat-1 among the gears studied. Total revenue earned after completion a trip varied considerably between BDT 1,307 to 1,562. Yearly, total net revenue reached at the maximum by Hookline (BDT 38,506), followed by Chandijal (BDT 38,377) and the minimum by Khalpata (BDT 33,885). The findings of this study are supposed to be helpful for policy makers in improving the current status of Golda fishery and relevant human livelihood as well as conserving the Sundarbans Mangrove Ecosystem.

The Sundarnbans mangrove forest has been an immense source of aquatic resources from time immemorial. Among the resources, harvesting of Giant Freshwater Prawn (Macrobrachium rosenbergii de Man 1879) plays an important role in the economy of the country, therefore, this investigation was carried out to assess the Gear Efficiency for Harvesting Artisanal Giant Freshwater Prawn Fisheries from the Sundarbans Mangrove Ecosystem in Bangladesh. Four types of non-mechanized crafts made of fourteen types of wood were found in harvesting Giant Freshwater Prawn. Crafts were varied from 6.25±0.35 to 8.2±0.71 m in length, 1.1±0.14 to 1.75±0.36 m in breadth and 0.65±1.07 to 1.55±3.16 m in depth with a carrying capacity of 0.40 - 1.00 MT with an economic life of 10±2.11 years. A total of eight types of gears, namely, Hookline, Behundijal, Badhajal, Charpata, Chandijal, Gillnet, Kathijal and KhalPata were found in Giant Freshwater Prawn fishing. Among them the Hookline was the only main primary active Giant Freshwater Prawn fishing gear while the rest of the seven gears were multi-species gears which harvest Giant Freshwater Prawn as a by-catch. Only 13.6% of 1,989 fishers were found to use Hookline; the rest, 86.4% of fishers used the seven other gears. They only harvest 3.24% Giant Freshwater Prawn as a bycatch. The highest daily harvest volume per boat (kg day-1 boat-1) was 1.00±0.96 for the Kathijal followed by 0.99±0.27 for the Badhajal and 0.99±0.42 for the Hookline. The highest annual catch per boat (kg boat-1 yr-1) which was 172.80±0.29 was recorded for the Hookline followed by 172.24±0.54 for the Chandijal and the lowest (152.08±0.21) for the Khalpata. Total annual catch by all the eight gears surveyed was estimated at 1318.60±0.37 kg from 1,428 unit gears, 545 individual boats and 1,989 individual fishers. Based on the above scenario, Hookline showed the best performance among the 8 gears used for Giant Freshwater Prawn harvesting in the Sundarbans by the small-scale artisanal fishery. It is believed that the findings and the recommendations of this study will be helpful to policy makers in improving the current status of Giant Freshwater Prawn fishery and relevant livelihood as well as conserving the SME ecosystem

Rice production and processing over the years has been on an increase with more small holders entering the business. This study on profitability of processing and marketing of small scale rice processors had as objective to analyse the profitability levels of rice processing and marketing by small scale processors, determine the value added to the commodity at each stage  and also identify the constraints faced by these processors. The study used primary data collected using well-structured questionnaire from millers only, miller traders for white/parboiled rice through a multistage sampling technique. Results showed that the net processing income (3,151,201), value added (8,147,456) and efficiency (138) for miller-traders of white rice was highest, followed by miller-traders for parboiled rice and lastly millers only. Results further showed that millers only had Benefit/cost ratio of 0.4 indicating that milling only is not profitable due to small quantities milled, and high fixed cost. Miller-traders for parboiled rice had a benefit/cost ratio of 2.3 implying that their venture is most profitable. Based on the results, it was recommended that millers only should purchase large quantities of paddy to enable them reduce the overhead cost. Also the services of parboilers should reflect in the sales price of parboiled rice so that the parboiling services can be paid for.

The study was conducted to know the existing turkey production system, supply chain mapping, and identifying the prospects and problems of turkey rearing in some selected areas of Bangladesh during October 2019 to December 2019. A total of 100 turkey raisers were surveyed following convenience method of sampling technique. The primary data were collected, analyzed accordingly and tabular presentation method was applied with the help of simple descriptive statistical measures e.g. frequency distributions, percentage, sum and means to illustrating the results. Profitability analysis was done on the basis of variable cost, fixed cost, return by using arithmetic means and percentages. The study revealed that 87 male and 13 female respondents were surveyed, of them cent percent found educated. About 56% turkey keeper’s main occupation was business, 27% service and 12% in farming while 88.57% involved with farming as secondary sources of income. Average landholding for homestead, cultivable and non-cultivable was 24.40, 129.71 and 29.47 decimal, respectively. About 59% farms started for commercial purpose, 32% for non-commercial purpose and 9% for both. About 60% respondents kept less than 50 turkeys and only 2% kept 501-1000 turkeys. Among the surveyed farms55% stopped their operation and 45% farms found running their business. Among the running farms cent percent were small-scale group. The average feed intake was 192.13 grams per day per bird at 20 weeks of age. Turkey laid on an average 139 eggs a year irrespective of variety and for hatching poults, the fertility and hatchability rate found between 65 to 100% and 50 to 90%, respectively. About 28% farmers experienced the deaths of turkey because of Cold, Pox, Ranikhet, Bird flu and unknown cases and 69.47% farmers took veterinary advice from Upazila Livestock Hospital and rest from other sources. Farmers to consumers were the most common and widely used marketing channel for egg, chick and adult turkey. The market intermediaries of turkey farm carried out different marketing functions e.g. buying and selling, pricing, transportation, sorting, distribution and market information. The average net return and benefit-cost ratio was BDT 127838.04 and 1.38, respectively for 50 turkeys per year. In the study, turkey rearing found some comparative benefit over chicken and ducks e.g. higher weight gain, forage eater, lower diseases rate and suitability for the country. The main problem of turkey rearing identified as market instability, lack of quality turkey feed, higher feed price, lack of proper marketing facility and training on turkey farming. In conclusion, the small-scale turkey farming could be a viable source of income for the rural people of Bangladesh after taking some remedial steps by the Government of Bangladesh for the aforesaid hindrances faced by the turkey farmers.

Poultry manure is a hazard to the environment and health due to the release of toxic substances as well as pathogenic microorganisms. The present study was undertaken to assess the current scenario of poultry waste management considering its social as well as environmental and health hazards. A questionnaire based survey was conducted in 36 commercial poultry farms (which included 15 broiler, 14 layer, 3 cockerel and 4 mixed farms) in Mymensingh district from February to June 2016. Most of the broiler and layer farms had between 500 to 2000 birds, while most of the cockerel farms had between 3000 to 4000 birds. The study showed that 69 percent of the poultry farmers were unaware of the health and environmental problems of the poultry waste. Majority of the small scale farmers disposed their droppings to fish ponds (31 percent) and agricultural farms (16 percent) directly, while only 6 percent farmers used those droppings in biogas plant. However, 53 percent farmers had knowledge about hygienic handling of poultry dropping, although only 19 percent of them used protective gloves during dropping handling. The profitability analysis revealed that average variable cost and fixed cost per farm per year were TK. 2,17,355 and TK. 3,93,106, respectively. The benefit cost ratio per farm per year poultry farming was 1.55. Considering the findings, it is suggested that proper poultry waste management could be highly beneficial for the farmers. On the other hand, improper dispose of poultry litter could be a cause for social, environmental and public health hazard. J. Bangladesh Agril. Univ. 17(1): 50–57, March 2019

Abstract Since 2002 the Greater Noakhali Aquaculture Extension Project (GNAEP) has been promoting rice-prawn (giant freshwater prawn, Macrobrachium rosenbergii) culture as a means of adding value to small-scale aquaculture systems in southeast Bangladesh. Over a period of two years there has been a rapid expansion of this culture system, crucial to which has been the development of partnerships between GNAEP and the private sector. Through a process of dialogue and confidence building, GNAEP has persuaded local businessmen to invest in prawn hatcheries, manufacture of fish meal (ground, sun-dried fish) bought directly from artisanal fishermen on Hatiya Island and in setting up a prawn purchasing center. These partnerships have supported the Project's primary objective of improving the livelihoods of the rural poor, through ensuring supplies of cheap post-larvae, partly as credit in kind, to farmers, through releasing poor fishermen from exploitative relationships with local money lenders and through creating competition in the local market. The influence of the private sector on local and national policy makers has been another advantage from the system.
