The potential of Indonesian bays as alginate producers was assessed by determining the stock of wild brown algae and exploring their biomass as alginophytes at the scale of entire bay, using a combination of field observations, remote sensing high resolution data and GIS tools. Ekas Bay in Lombok Island presented a stock of brown macroalgae which varied with season and species: for Padina the biomass reached 97.85±12.63 and 79.54±2.53tons in May/June and November respectively; for Sargassaceae species, it reached 669.70±109.64 and 147.70±77.97tons in May/June and November respectively. The best alginate yields occurred during the May/June period: Padina could produce 9.10±0.06tons DW of alginates. Interestingly, Sargassum/Turbinaria together allow 207.61±0.42tons DW of alginates. This study suggests that wild Sargassaceae represent an interesting stock in terms of biomass, alginate yield and M/G ratio.
本研究通过野外观测、高分辨率遥感数据和 GIS 工具相结合，评估了印度尼西亚各海湾作为褐藻酸钠生产地的潜力，测定了野生褐藻的蕴藏量，并对整个海湾的褐藻生物量进行了探索，评估其作为产褐藻胶植物的潜力。龙目岛的埃卡湾有不同季节和种类的褐藻：在 5/6 月和 11 月，叶状马尾藻的生物量分别达到 97.85±12.63 和 79.54±2.53 吨；在 5/6 月和 11 月，马尾藻科的生物量分别达到 669.70±109.64 和 147.70±77.97 吨。褐藻酸钠产量最高的时期是在 5/6 月：叶状马尾藻可以生产 9.10±0.06 吨 DW 的褐藻酸钠。有趣的是，马尾藻/鹿角菜总共可以生产 207.61±0.42 吨 DW 的褐藻酸钠。本研究表明，野生马尾藻科在生物量、褐藻酸钠产量和 M/G 比方面都具有很大的潜力。
