Aquaponics is an attempt to control water quality such that all living beings (fish, plants, and bacteria) can live. In this study, the tilapia fish, , and the plants, mustard () and millet (), were raised in a low-cost aquaponics system (Nutrient Film Technique or NFT). The study also examined the microbial load and various water quality parameters. According to the USEPA rules, the water quality attributes of NFT have to be stable. During different culture periods, the growth rate of fish in the NFT system was gradually increased significantly ( < 0.01). The ANOVA analysis revealed that the recorded biochemical-values of NFT-raised fishes were less significant ( < 0.04) (than control fishes). When compared to the NFT-grown mustard plant, the biochemical content of NFT-raised millet plant was significantly lower ( < 0.003). Currently, the phytochemical content has been found to be high in NFT grown plants. Chlorophyll 'a' level was high (8.17 mg) in NFT and low (2.34 mg) in controls. The maximum chlorophyll 'b' level in plants produced using NFT was 8.45 mg, whereas the lowest (0.84 mg) was recorded in control plants. Carotenoid concentration was high (707 mg) in plants cultivated using NFT, but low (239 mg) in control plants. Furthermore, when compared to the control (24 colonies), the NFT produced the greatest number of microbial colonies (57 colonies) at 10dilution. Thus the adoption of NFT techniques shows its usefulness in terms of reduced cost and water usage and the reduction in microbial load (when fish and plants are raised together). Therefore, this research-output supports the potential of NFT-technology as an integrated aquaculture approach for future.

标准化鱼菜共生系统中非生物微生物对生产高价值鱼类和植物生物质的协同效应

鱼菜共生是一种控制水质以使所有生物（鱼类、植物和细菌）都能生存的尝试。在这项研究中，罗非鱼 以及植物芥菜 () 和小米 () 在低成本鱼菜共生系统（营养膜技术或 NFT）中饲养。该研究还检查了微生物负荷和各种水质参数。根据USEPA规定，NFT的水质属性必须稳定。在不同的养殖时期，NFT系统中鱼类的生长率逐渐显着增加（<0.01）。方差分析显示，NFT 饲养的鱼类记录的生化值不太显着 (< 0.04)（与对照鱼相比）。与 NFT 种植的芥菜植物相比，NFT 种植的小米植物的生化含量显着较低（<0.003）。目前，NFT 种植的植物中植物化学物质含量很高。NFT 中的叶绿素“a”水平较高（8.17 毫克），而对照组的叶绿素“a”水平较低（2.34 毫克）。使用 NFT 生产的植物中叶绿素“b”的最高水平为 8.45 毫克，而对照植物中记录的最低叶绿素“b”水平为 0.84 毫克。使用 NFT 培养的植物中类胡萝卜素浓度较高（707 毫克），但对照植物中类胡萝卜素浓度较低（239 毫克）。此外，与对照（24 个菌落）相比，NFT 在 10 倍稀释度下产生了最大数量的微生物菌落（57 个菌落）。因此，NFT 技术的采用显示了其在降低成本和用水量以及减少微生物负荷（当鱼和植物一起饲养时）方面的有用性。因此，这项研究成果支持了 NFT 技术作为未来综合水产养殖方法的潜力。
