Abstract

To meet the increasing demand for kappa carrageenan, several strategies have been employed to improve eucheumatoid seaweed productivity, such as nutrient enrichment (NE) and the application of some efficient farming methods (FM). This study aims to investigate the interaction of NE (applied as ammonium phosphate at 3.5 g L⁻¹) and farming method on the performance of the eucheumatoid seaweed Kappaphycus alvarezii. Three farming methods, that is, Sway (SW), Spring (SP), and modified fixed-off bottom (MFOB), were employed for nutrient-enriched (NE) and non-enriched control fronds for a period of 45 days. NE significantly improved the growth and carrageenan yield of the seaweed and afforded protection against the incidence of ice-ice disease; meanwhile, the effect of FM and NE-FM interaction was non-significant. NE increased the gel strength of the extracted carrageenan; meanwhile, SP farm led to the highest gel strength, followed by MFOB.

营养物质富集和养殖方法对红海藻 Kappaphycus alvarezii 性能的交互作用

为了满足对卡帕卡拉胶日益增长的需求，人们采用了多种策略来提高杜仲海藻的生产力，如营养富集（NE）和应用一些高效养殖方法（FM）。本研究旨在探讨营养富集（以磷酸铵的形式施用，浓度为 3.5 g L-1）和养殖方法对杜氏海藻（Kappaphycus alvarezii）生长性能的影响。对富含营养物质（NE）和未富含营养物质的对照叶片采用了三种养殖方法，即摇摆（SW）、春播（SP）和改良固定脱水（MFOB），为期 45 天。结果表明，NE能明显改善海藻的生长和卡拉胶产量，并能防止冰冻病的发生；而FM和NE-FM交互作用的影响不明显。NE 提高了提取卡拉胶的凝胶强度；同时，Spring Farm 的凝胶强度最高，其次是 MFOB。

期刊介绍： Aquatic Botany offers a platform for papers relevant to a broad international readership on fundamental and applied aspects of marine and freshwater macroscopic plants in a context of ecology or environmental biology. This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences of disturbance and stressors (e.g. environmental fluctuations and climate change, pollution, grazing and pathogens), use and management of aquatic plants (plant production and decomposition, commercial harvest, plant control) and the conservation of aquatic plant communities (breeding, transplantation and restoration). Specialized publications on certain rare taxa or papers on aquatic macroscopic plants from under-represented regions in the world can also find their place, subject to editor evaluation. Studies on fungi or microalgae will remain outside the scope of Aquatic Botany.
