A 60-day experiment was carried out to optimize the mica dosage for the best growth of the plant (holy basil) and fish (Nile tilapia) in aquaponics. Mica is a potassium-bearing phyllosilicate mineral rock used as a fertilizer in agriculture. Four mica dose treatments of C (0 g l⁻¹), T1 (2 g l⁻¹), T2 (4 g l⁻¹), and T3 (6 g l⁻¹) were taken with equal bacterial (Bacillus megaterium) dosages of 5 × 10⁸ CFU ml⁻¹ in all the treatments. The experiment was performed in aquaponics units with Nile tilapia (Oreochromis niloticus) and holy basil (Ocimum tenuiflorum) stocked at 1.14 kg m⁻³ and 28 plants m⁻², respectively. The results showed that the yield of basil was highest in T2 (365.66 ± 34.27 g), followed by T3 (362.10 ± 19.99 g), T1 (337.70 ± 15.15 g), and C (324.26 ± 16.88 g). Tilapia growth was highest in C (10.79 ± 0.35 g) followed by T1 (10.45 ± 0.12 g), T2 (10.31 ± 0.09 g), and T3 (10.18 ± 0.08 g). However, there was no significant difference in fish growth corresponding to different treatments. Thus, the treatment which showed the best compromised overall growth was T2 (4 g l⁻¹ mica). Thus, 4 g l⁻¹ mica can be suggested as optimum mica dose for Nile tilapia and holy basil in an aquaponic system.

进行了为期60天的实验，以优化云母剂量，以使水培法中的植物（圣罗勒）和鱼类（尼罗罗非鱼）达到最佳生长。云母是一种含钾的页硅酸盐矿物岩，在农业中用作肥料。分别以5×的相等细菌剂量（巨型芽孢杆菌）进行四次云母剂量的C（0 g l ^-1），T1（2 g l ^-1），T2（4 g l ^-1）和T3（6 g l ^-1）剂量处理。在所有处理中为10 ⁸  CFU ml ^-1。该实验是在鱼菜共生单位中进行的，其中尼罗罗非鱼（Oreochromis niloticus）和圣罗勒（Ocimum tenuiflorum）的放养量为1.14 kg m ^-3和28株m ^-2的植物。结果表明，罗勒的产量最高的是T2（365.66±34.27 g），其次是T3（362.10±19.99 g），T1（337.70±15.15 g）和C（324.26±16.88 g）。罗非鱼生长最高的是C（10.79±0.35 g），其次是T1（10.45±0.12 g），T2（10.31±0.09 g）和T3（10.18±0.08 g）。但是，在不同的处理方式下，鱼类的生长没有显着差异。因此，显示出最不利的总体生长的处理是T2（4 g l ^-1云母）。因此，对于水培系统中的尼罗罗非鱼和圣罗勒，建议使用4 g l ^-1云母作为最佳云母剂量。
