Abstract：
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.
摘要：
通过确定野生褐藻的存量并在整个海湾的规模上探索其作为藻类植物的生物量，评估了印尼海湾作为藻酸盐生产者的潜力。结合现场观测，遥感高分辨率数据和GIS工具。龙目岛的Ekas湾呈现出褐藻种群，随季节和种类而异：对于帕迪纳，5月/6月和11月的生物量分别达到97.85±12.63和79.54±2.53吨；对于Sargassaceae物种，5月/6月和11月分别达到669.70±109.64和147.70±77.97吨。最佳的藻酸盐产量发生在5月/6月期间：Padina可以生产9.10±0.06吨DW的藻酸盐。有趣的是,马尾藻/Turbinaria一起允许207.61±0.42吨DW藻酸盐。这项研究表明，野生马尾科在生物量方面代表了一个有趣的种群，藻酸盐产量和M/G比。
