Abstract

Nutrient enrichment is one of the main reasons causing water quality deterioration and eutrophication in aquaculture systems, such as tanks, ponds, and natural water bodies where cage aquaculture is located. The integration of aquatic plants and substrates synergistically utilises nutrients for the development of biofilm and plant growth, thus improving the water quality in tanks. The experiment was performed in three trials to assess the use of commercial plants integrated with substrates in enhancing nutrient removal in nutrient-enriched mesocosms. Among the plants, the combination of water spinach and lemon basil exhibited significantly higher (P < 0.05) nutrient removal without causing adverse effects on plant growth when compared to the other treatments. For the substrates, the lava rock and bamboo showed the highest (P < 0.05) periphyton development and productivity. The integration of water spinach and lava rock resulted in the highest (P < 0.05) nutrient removal and plant relative growth rates indicating the positive effects of synergistic interaction between plants and microbial-periphyton colonised substrates. A total of 27 bacterial phyla (mainly non-pathogenic) were identified in the integrated water spinach and lava rock substrate treatment. Microbial community structure analysis showed that Proteobacteria, Planctomycetota, Verrucomicrobiota and Bacteroidota were the main groups found in water, roots of water spinach, and substrates. The highest (P < 0.05) bacterial diversity was observed in the substrates, followed by plant roots and water. This study illustrated that the water quality could be significantly improved by integrating suitable plants and microbial-periphyton colonised substrates in tanks.

植物与富含微生物的基质的协同组合改善了植物-基质综合系统的水质

养分富集是造成水产养殖系统（如水箱、池塘和网箱养殖所在的天然水体）水质恶化和富营养化的主要原因之一。水生植物与底质的结合可协同利用养分，促进生物膜和植物的生长，从而改善水箱中的水质。实验分三次进行，以评估商业植物与底质的结合在提高营养富集中置池中营养物质去除率方面的作用。在这些植物中，与其他处理相比，蕹菜和柠檬罗勒组合的养分去除率明显更高（P < 0.05），且不会对植物生长造成不利影响。在基质方面，熔岩和竹子显示出最高的（P < 0.05）浮游生物发育和生产力。将蕹菜和熔岩整合在一起，养分去除率和植物相对生长率最高（P < 0.05），这表明植物和微生物-浮游生物定殖基质之间的协同作用产生了积极影响。在蕹菜和熔岩基质综合处理中，共鉴定出 27 个细菌门（主要是非致病菌）。微生物群落结构分析表明，在水、蕹菜根部和基质中发现的主要群落是变形菌群（Proteobacteria）、平面菌群（Planctomycetota）、蛭石菌群（Verrucomicrobiota）和类杆菌群（Bacteroidota）。基质中的细菌多样性最高（P < 0.05），其次是植物根部和水。这项研究表明，通过在水箱中添加合适的植物和微生物-浮游生物定殖基质，可显著改善水质。

期刊介绍： The Asian Fisheries Science (AFS) was first published in 1987. It is an open access SCOPUS indexed publication of the Asian Fisheries Society. Four regular issues are published annually in March, June, September and December. In addition, special issues are published on specific topics. Full texts of the articles are available for free download and there is no publication fee. The journal promotes fisheries science which has an international appeal with special focus on Asian interests.
