Commercial Seaweed Market Dynamics

Increasing demand for commercial seaweed in animal feed industry drives the market growth

Animals like sheep, cattle, and horses that live in coastal areas eat seaweed, especially in European countries where brown seaweed is available in a large amount. The availability of seaweed for animals increases with the production of seaweed meals. Dried seaweed is milled to a fine powder and used as animal feed. Norway is the early producer of seaweed meal, using Ascophyllum nodosum variety. In France, seaweed feed is made from the Laminaria Digitata variety. In Iceland, both Ascophyllum and Laminaria species are used for making animal feed, and in the United Kingdom, the Ascophyllum variety of seaweed is used for preparing seaweed. The dried form of seaweed can be stored for one year without deterioration. Seaweed is a rich source of minerals like potassium, phosphorus, magnesium, calcium, sodium, chlorine and sulphur, trace elements and vitamins. Trace elements are essential for mammals in small quantities for the proper functioning of enzymes and proteins, which are involved in many physiological, biochemical and metabolic processes that contribute to growth and production. For poultry, Ascophyllum meal is essential to increasing the iodine content of the eggs. For pigs, seaweed consumption is beneficial for increasing the meat yield. Consumption of seaweed is good for cattle and sheep to increase milk production. Some studies showed that regular consumption of seaweed is beneficial to increasing milk production, which helps increase farmers' income. Norway alone produces about 15 000 tons of seaweed meal annually. Companies in Australia, Canada, Ireland, Norway, the United Kingdom and the United States of America were advocating the use of seaweed meal as a feed additive for sheep, cattle, horses, poultry, goats, dogs, cats, and other animals. The immunity system of some animals is boosted by the regular consumption of Canadian seaweed meals. These factors drive the market growth in the forecast period.

They perform a good role in skin nourishment and help to boost immunity. It also helps to regulate blood sugar levels. It is consumed by various organisms such as crustaceans, fish, worms and even humans. Red algae are a rich calcium source and also a vitamin supplement. The high nutritional value of the red algae increases the consumption of various organisms’ which drives market growth.

Commercial Seaweed Market Geographical Share

Asia Pacific is the dominating region during the forecast period

Asia Pacific dominated the market growth due to increasing demand for natural, healthy and nutritious food like commercial seaweed. India is the largest producer of seaweed. According to the Central Marine Fisheries Research Institute, Kerala, India, has the potential to produce around 9.7 million tons of seaweed per year. India has 342 potential sites for cultivating marine plants and algae. The government of India supports the cultivation of commercial seaweed. As cattle feed, an increase in seaweed consumption in India helped grow the region's market. Seaweed is used to minimize cow fewer. It also helps in improving resistance to diseases as well as aids in maintaining the balance of micronutrients. It is also used to improve fat and Iodine level in cattle milk. The growing use of commercial seaweed in the feed industry helps grow the Asia Pacific market.
