MUSCAT: A research study conducted by Sultan Qaboos University has identified over 400 species of seaweed in Oman’s seas, with 18 species being unique to the country, most of which are found in the Dhofar Governorate. The study emphasizes the commercial potential of these marine plants, noting that they can be cultivated without the need for fresh water or arable land, making them a sustainable and valuable natural resource. Researchers documented the composition and growth characteristics of these species, comparing findings with previous studies in other regions, particularly in cases where data on certain plant families was limited.
Dr. Ahmed Ali Al Alawi, Associate Professor at the College of Agricultural and Marine Sciences, explained that seaweeds are classified by color into brown, green, and red algae, and are also known as sea plants or sea vegetables. The study provides essential data to assess and manage Omani seaweed resources effectively, highlighting their potential economic value. Detailed monitoring of growth stages and species characteristics will aid in future utilization strategies, ensuring sustainable exploitation while protecting the marine ecosystem.
The research revealed significant opportunities for the use of Omani seaweed in diverse fields, including protein and colloid production, pharmaceutical applications, and carbon dioxide absorption. While seaweed is not traditionally part of Omani culture, the study positions it as a high-value resource for both industrial and medicinal purposes. East Asian countries such as Japan, China, Korea, and the Philippines have long incorporated seaweed into their cuisine, whereas globally its applications have mainly focused on industrial uses like gelling and thickening agents, contributing to a global market projected to reach $44 billion by 2034.
In addition to traditional and industrial applications, seaweed is rich in micronutrients, macronutrients, and bioactive compounds with medicinal properties. The study underscores its potential in food, medicine, cosmetics, and agriculture, offering a sustainable economic resource for Oman. By providing comprehensive data on species distribution, growth patterns, and chemical composition, the research lays the groundwork for future exploitation and commercialization, contributing to the national economy and supporting sustainable development goals in the marine and agricultural sectors.
