2013年7月至12月，在欧盟资助的农业和营养推广项目下，开展了参与性行动研究，以设计和建造一种名为IFCAS（综合浮笼水培系统）的技术，用于在孟加拉国巴里萨尔地区的阴影池塘中种植鱼类和蔬菜。在这里，术语aqua、geo和ponics分别指池塘水、池塘泥/土壤和耕作。在荫蔽池塘中生产和定期捕捞鱼类以及在周围堤坝上种植蔬菜供家庭消费受到限制。为了克服这些困难，在9个遮荫池塘（5个高度遮荫池塘（HSP）和4个中度遮荫池塘（MSP））中的每一个中设置IFCAS（3.66 m x 2.44 m = 9 m（2）），其中GIFT罗非鱼品系（Orechromis niloticus）以100 m（-3）笼的比率放养。在池塘中，以1：2：2：1的比例和14，820公顷（-1）的比例放养鲤鱼（Catla catla，Labeo rohita，Cirrhus arrhosus和Cyprinus carpio）。罗非鱼投喂漂浮饲料，鲤鱼投喂补充饲料。蔬菜生长在IFCAS支架上，罗非鱼生长在下面建造的网箱中。HSP家庭的妇女成员充分参与了IFCAS的蔬菜和鱼类生产行动研究。参与家庭分别在实验开始后的1.5个月和1个月内开始食用IFCAS的蔬菜和罗非鱼。在四个月内，记录了20公斤家庭（-1）的平均鱼消费量，其中50%以上是来自IFCAS的罗非鱼。总体而言，MSP的鱼类和蔬菜产量高于HSP。财务分析结果表明，该项目的收益成本比大于1，说明该项目对农户的投资效率较高。(C)2015作者由爱思唯尔公司出版
participatory action research was carried out from July to December 2013 to design and construct a technology known as IFCAS (integrated floating cage aquageoponics system) for growing fish and vegetables in shaded ponds in the Barisal region of Bangladesh under the EU funded ANEP (Agriculture and Nutrition Extension Project). Here the terms aqua, geo and ponics means pond water, pond mud/soil and cultivation, respectively. Producing and regularly harvesting fish in shaded ponds and growing vegetables on surrounding dykes for household consumption was constrained. To overcome the difficulties, an IFCAS (3.66 m x 2.44 m = 9 m(2)) was set in each of 9 shaded ponds - 5 highly shaded ponds (HSP) and 4 moderately shaded ponds (MSP) - in which GIFT tilapia strain (Orechromis niloticus) was stocked at the rate of 100 m(-3) cage. In the ponds, carp species (Catla catla, Labeo rohita, Cirrhinus cirrhosus and Cyprinus carpio) were stocked at the ratio of 1:2:2:1, and at the rate of 14,820 ha(-1). Tilapia were fed floating feed and the carp were fed with supplementary feed. Vegetables were grown on the IFCAS scaffold, and tilapia were grown in the net-cage constructed underneath. Women members of HSP households participated fully in the action research in the production of vegetables and fish in IFCAS. Participating households started consuming vegetables and tilapia from IFCAS within 1.5 and 1 month of the start of the experiment, respectively. Average fish consumption of 20 kg household(-1) was recorded within four months, of which more than 50% was tilapia from IFCAS. Overall fish and vegetable production was higher in MSP as compared to HSP. A financial analysis showed the benefit-cost ratio of IFCAS was >1, indicating the investment efficiency of IFCAS for farmers. (C) 2015 The Authors. Published by Elsevier B.V.
