摘要

稻鱼结合是一种以水稻为主要产业,以鱼类生产为额外收入的综合耕作系统。本研究旨在确定受访者的社会经济特征、文化习俗、盈利能力以及稻鱼养殖户面临的问题和制约因素。在广泛种植水稻和鱼类的基础上,选择了Sherpur地区进行研究。采用简单随机抽样的方法,采用半结构化访谈法对40名稻鱼养殖户进行初步资料收集。采用表格分析和功能分析两种方法对收集的数据进行分析。社会经济分析表明,37.5%的调查对象年龄在41-50岁之间,12.5%的调查对象不识字,55.7%的调查对象以农业为主要职业,50%的调查对象家庭年收入在15 -25万塔卡之间。研究还表明,约42.5%的养殖户拥有自己的小区,62.5%的养殖户在水田进行商业养殖,55%的养殖户从事单一养殖,47.5%的受访者从私人孵化场收集鱼种,单性罗非鱼主要在水田养殖,70%的受访者使用现成饲料饲养。盈利能力分析表明,每公顷毛收益、净收益和毛利率分别为355180塔卡、230879塔卡、246179塔卡。未贴现的收益成本比为2.86。该研究还确定了与稻鱼结合养殖有关的一些问题和制约因素。97.5%和95%的受访者分别表示缺乏优质种苗和推广服务是他们面临的主要问题。种稻养鱼是农村人民改善生计的新选择。政府和其他有关组织应采取必要措施,改善米鱼共生的情况

CULTURAL PRACTICE AND PROFITABILITY OF RICE-CUM-FISH CULTURE IN A SELECTED AREA OF BANGLADESH
The rice-cum-fish culture is an integrated farming system in which, rice is the main enterprise and fish production is taken as additional means to secure extra income. The present study was designed to identify the socioeconomic characteristics of the respondents, cultural practices, profitability and problems and constraints faced by the rice-cum-fish farmers. Sherpur district was selected for the study on the basis of extensive cultivation of rice-cum-fish culture. The simple random sampling technique was used for primary data collection from 40 rice-cum-fish farmers through semi-structured interview schedule. Both tabular and functional analyses were used to analyze the collected data. Socioeconomic analysis showed that 37.5% of the respondents were aged between 41-50 years, 12.5% of the respondents were illiterate, 55.7% respondent’s primary occupation was agriculture and 50% of the household annual income was between Tk. 150000-250000. The study also showed that about 42.5% of farmers have their own plot, 62.5% of farmers cultured fish in the paddy field commercially, 55% farmers were engaged with monoculture, 47.5% of the respondents collected their fingerling from private hatcheries, monosex tilapia was mainly cultured in the paddy field and 70% respondents used ready feed for feeding. The profitability analysis showed that per hectare gross return, net return, and gross margin was found to be Tk. 355180, Tk. 230879, Tk. 246179, respectively. Undiscounted benefit- cost ratio was found to be 2.86. The study also identified some of the problems and constraints associated with rice-cum-fish culture. About 97.5% and 95% of the respondents replied that lack of good quality seed and fingerling and lack of extension services were their main problems, respectively. Rice-cum-fish farming is the new option for rural people to improve their livelihood. Government and other concern organizations should take necessary steps to improve the rice-cum-fish cul
