Muscat: A research study carried out by Sultan Qaboos University has discovered over 400 species of seaweed in the waters of Oman, with 18 of these species being exclusive to the nation. The majority of these species are located in the Dhofar Governorate.
The research emphasized the considerable potential for commercial use of Omani seaweed, especially since it does not necessitate fresh water or arable land.
Additionally, it documented the composition and traits of these marine plants by observing their various growth stages. Species were chosen based on comparisons with earlier studies conducted in different regions and under varying conditions, particularly in instances where research on specific plant families was limited.
Dr. Ahmed Ali Al Alawi, an Associate Professor at the College of Agricultural and Marine Sciences at Sultan Qaboos University, clarified that seaweeds are generally categorized by color (pigmentation) into three primary groups: brown algae, green algae, and red algae. Seaweeds are large aquatic algae, also referred to as sea plants or sea vegetables. The study has offered essential information for improved assessment and management of this natural resource and its economic potential in Oman.
He further mentioned that the study uncovered significant opportunities for the application of Omani seaweed across various sectors. For example, certain species have been recognized as appropriate for protein and colloid production, while others exhibit potential for highly effective pharmaceutical uses and have a notable ability to absorb carbon dioxide.
Dr. Al Alawi pointed out that seaweed is not commonly utilized in Omani culture, and published information on locally occurring species has been scarce.
He highlighted that countries in East Asia, including Japan, China, Korea, and the Philippines, have historically integrated seaweed into their culinary practices. Conversely, in other regions of the globe, its application has primarily been limited to industrial uses, serving as sources for gelling and thickening agents such as agar, alginate, and carrageenan. The movement of Asian populations to Western nations, along with recent advancements in industry, has resulted in a significant increase in the use of seaweed, propelling global demand to an estimated $18 billion by 2024. This amount is anticipated to grow to $44 billion by 2034.
Beyond its traditional applications, seaweed is abundant in micronutrients, macronutrients, and a variety of bioactive compounds that possess medicinal benefits. Consequently, products derived from seaweed are now utilized in a diverse array of sectors, including food, healthcare, cosmetics, and agriculture. This research will undoubtedly enhance the use of this vital economic resource within the national economy.
