摘要

这项研究是通过在孟加拉国中小企业进行的24项个人调查进行的,调查覆盖了孙德尔本斯的16条河流/运河和32个地点(三分之一的面积),通过直接采访随机选择的1989名渔民,他们来自545艘非机械化船只和8种类型的1428个活动齿轮。信贷来源、大单协议、价格变异性、渔船/渔具所有者与捕鱼劳工之间的利润分配协议、渔获量以及渔民与登陆中心之间的关系(即亲密度和预期市场价格)被发现是决定研究区域渔获物登陆地点的决定性因素。渔民可以进入正规信贷市场(即定期银行或合作社),利率为13±2.83(11-15)%。然而,非政府组织提供的利率明显高于银行利率(平均值:45±31,范围:18-76%)。一些手续阻碍了渔民从银行和非政府组织获得贷款。在扣除运营成本后,盖尔达渔获价值的60-100%被渔船和渔具所有者拿走。劳动份额也因工作类型而异(捕捞、晒干、运输、船上烹饪等)。在着陆中心,“加尔达”的平均价格从290新元到750公斤不等。2006年,“加尔达”在着陆中心和国际市场的平均价格分别为290泰铢和750泰铢。森林部作为孟加拉国中小企业水域内水生资源管理的法定权威机构,应关注小规模渔业的可持续管理,以确保Galda的可持续增长率,并保护过度开发。为改善小渔民的经济状况,需要适当和宽松的金融和信贷支持。因此,本研究的结果和建议应有助于决策者改善加尔达渔业和相关人类生计的现状,并保护孙德尔本斯红树林生态系统。

Assessment of External Supports for Harvesting Artisanal Galda (Macrobrachium Rosenbergii De Man) Fisheries from the Sundarbans Mangrove Ecosystem in Bangladesh
The study was conducted through 24 individual surveys in the SME of Bangladesh covering 16 river/canals and 32 locations (one-third area) of the Sundarbans by direct interviews of randomly selected 1,989 fishermen from 545 non-mechanized boats and 1,428 active gears from eight types of gear. The source of credit, agreement of Dadan, variability in prices, profit distribution agreement between boat/gear owner and the fishing labour, catch volume, and the relation between the fisher and the landing centers (i.e., intimacy and expected market prices) were found to be determinant factors in determining the place for landings of the harvested catches in the study area. There was access of fishers to the formal credit markets (i.e. scheduled banks or cooperatives) at 13±2.83 (11-15)% interest. However, the rate of interest offered by the NGOs was significantly higher (mean: 45±31, range: 18-76%) than the bank rates. A number of formalities were found to inhibit fishers to receive credit from Banks and NGOs. About 60-100% of the value of Galda catch, after covering the operational costs, was taken by the boat and gear owner. The share of the labor also varied by the type of work performed (catching, drying, transporting, cooking on boat etc.). The average prices of Galda at landing centers are varied from BDT 290 to 750 kg-1. The average prices of Galda at landing centers and in international markets were BDT 290 and 750 kg-1, respectively in 2006. The Department of Forest, being the legal authority in the management of aquatic resources inside the waters of the SME of Bangladesh should care the sustainable management of small-scale fisheries to ensure a sustainable growth rate of Galda, and protect over exploitation. Proper and easy financial and credit supports is needed for the economic betterment of the small fishers. Hence the findings and the recommendations of this study is supposed to be helpful for policy makers in improving the current status of Galda fishery and relevant human livelihood as well as conserving the Sundarbans Mangrove Ecosystem.
