Alaria is a genus of brown alga (Phaeophyceae) comprising approximately 17 species. Members of the genus are dried and eaten as a food in Western Europe, China, Korea, Japan (called sarumen), and South America 17:56, 1 August 2010 (UTC). Distribution of the genus is a marker for climate change, as it relates to oceanic temperatures.
The most common species, Alaria esculenta is a large brown seaweed common on the shores of the British Isles. It has been studied for its potential for aquaculture.
Alaria is a genus of highly variable brown algae, and a member of the order Laminariales, more commonly known as kelp. It has mature sporophytes as small as 15 centimetres (5.9 in) and as large at 15 metres (49 ft) in length. All species’ sporophytes consist of a ramified holdfast, an unbranched cylindrical stipe, and a blade with a percurrent, cartilaginous midrib,Alaria is frequently found with lacerations running from the margin to the midrib caused by the ravages of the sea.
Alaria the second largest genus of Laminariales, with about 17 currently recognized species. However, due to its highly plastic morphology, the kelp has over 100 specific and subspecific names, which have arisen since it was first described in 1830. These synonyms have been tailored down to the present species through genetic comparisons.
Alaria is most commonly found in far northern waters of the Pacific and Atlantic oceans, with the greatest variety of species concentrated in the north Pacific. More specifically, it has been found on the coasts of England, Ireland, Scotland, Iceland, Greenland, Denmark, Norway, Japan, China, Korea, Canada, and the United States.
