Abstract

An experiment for 90 days was performed to optimise the stocking density of pangasius(Pangasianodon hypophthalmus) with basil (Ocimum basilicum L.) in a nutrient film technique(NFT) based aquaponics. The experiment had four treatments with different stockingdensities of pangasius as T1 (2.5 kg m-3), T2 (2.75 kg m-3), T3 (3.0 kg m-3) and T4 (3.25 kg m-3)with a constant plant density of 24 plants m-2 and control viz., C (2.5 kg m-3 withoutplants). Significant (p<0.05) difference in final body weight of fish was found among thetreatments and control. The highest fish biomass was recorded in T3 (10.29±4.41 kg m-3)followed by T4, T2, T1 and C. The highest plant yield was found in T4 (510.90±6.25 g);however, no significant difference was found between T4 and T3. No significant (p>0.05)difference in macro and micronutrient content of basil leaves was recorded in T4 and T3.The physiological parameters (hematological, serum biochemical and anti-oxidant stressenzymes) were found to be within the acceptable range. Considering the water qualityparameters, fish growth, total biomass of fish, fish physiological responses, basil yield andnutrient content, the stocking density of 3.00 kg m-3 (pangasius) with 24 plants m-2 of basilcould be recommended for basil-pangasius aquaponics.

基于营养膜技术（NFT）的鱼菜共生中罗勒（Ocimum basilicum L.）对鲮鱼（Pangasianodon hypophthalmus）幼苗的放养密度优化

进行了一项为期 90 天的实验，以优化基于营养膜技术（NFT）的鱼菜共生中罗勒（Pangasianodon hypophthalmus）的放养密度。该试验有四个处理，分别为 T1（2.5 千克/米-3）、T2（2.75 千克/米-3）、T3（3.0 千克/米-3）和 T4（3.25 千克/米-3），鱼芒的放养密度分别为 2.5 千克/米-3、2.75 千克/米-3、3.0 千克/米-3 和 3.25 千克/米-3，植物密度恒定为 24 株/米-2，对照组为 C（2.5 千克/米-3，不含植物）。在 T4 和 T3 中，罗勒叶片的宏量和微量营养素含量存在显著差异（p0.05）。生理参数（血液学、血清生化和抗氧化应激酶）均在可接受范围内。考虑到水质参数、鱼类生长、鱼类总生物量、鱼类生理反应、罗勒产量和营养成分含量，建议罗勒-鲮鱼鱼菜共生的放养密度为 3.00 kg m-3（鲮鱼）加 24 株 m-2 罗勒。关键词：鱼菜共生；养殖废水；罗勒；营养膜技术；鲮鱼
