The study evaluates optimum hydraulic loading rate (HLR) based on the fish and plant production performance and nutrient removal percentage in aquaponics. The growth of Gotukola (Centella asiatica (L.))—a leafy vegetable as well as traditional medicinal plant—and koi carp (Cyprinus carpio var. koi.)—a high demand ornamental fish—were evaluated at three different HLRs, viz. 2.6 m day⁻¹ (T1), 7.8 m day⁻¹ (T2), and 13.0 m day⁻¹ (T3). Treated aquaculture wastewater was utilized in a combination of the freshwater in 1:1 ratio with 2.1 kg m⁻³ fish stocking density. The highest fish mean length; weight; feed conversion ratio; specific growth rate; NH₃, NO₂⁻, and NO₃⁻ removal percentage; and plant growth parameters were observed. Considering fish (koi carp) and plants (Gotukola) growth parameters as well as nutrient removal percentages, a HLR of 7.8 m day⁻¹ was found to be the optimum in aquaponics.

该研究根据鱼类和植物的生产性能以及鱼菜共生中的营养去除率来评估最佳水力负荷率（HLR）。Gotukola的增长（积雪草（L）） -多叶蔬菜以及传统的药用植物和锦鲤（鲤鱼变种锦鲤） -高需求的观赏鱼是在三个不同的HLR，即评估。2.6 m天^-1（T1），7.8 m天^-1（T2）和13.0 m天^-1（T3）。处理过的水产养殖废水以1：1比例的淡水与2.1 kg m ^-3的鱼群密度结合使用。鱼的平均长度最高；重量; 饲料转化率 比增长率；NH ₃，NO ₂ ^-和NO ₃ ^-去除百分比; 观察植物生长参数。考虑到鱼类（锦鲤）和植物（Gotukola）的生长参数以及养分去除率，发现7.8 m天^-1的HLR在鱼菜共生中是最佳的。
