Saccharina latissima is a brown alga (class Phaeophyceae), of the family Laminariaceae. It is known by the common names sugar kelp, [2] sea belt, [3] and Devil's apron, [4] and is one of the species known to Japanese cuisine as kombu . [5] It is found in the north Atlantic Ocean, Arctic Ocean and north Pacific Ocean. It is common along the coast of Northern Europe as far south as Galicia Spain. In North America, it is found on the East Coast down to Long Island, although historically extended down to New Jersey [6] and on the West Coast down to the state of Washington. On the coast of Asia, it is found south to Korea and Japan. [7]

Description

Saccharina latissima is a yellowish brown colour with a long narrow, undivided blade that can grow to 5 metres (16 ft) long and 20 centimetres (7.9 in) wide. The central band is dimpled while the margins are smoother with a wavy edge, this is to cause greater water movement around the blades to aid in gas exchange. The frond is attached to the rock by stout rhizoids about 5 mm in diameter [3] in the intertidal and sublittoral zones by a claw-like holdfast and a short, pliable, cylindrical stipe. [8]

Ecology

Saccharina latissima is an ecologically important system. It is a primary producer, delivering plant material to the coastal food web. The three-dimensional forests also serve as a habitat for animals, resulting in a high biodiversity. Fish, shellfish and other animals find food and hiding places within these forests. [9]

It can be infected by the pathogenic fungus (to kelp) Phycomelaina laminariae . [10]

Human use

Sugar kelp is used as a food in many places where it grows, one of many species often called kombu. Sugar kelp can be used as a vegetable in salads but is most frequently used in soups and stocks where it provides savory flavors and is especially highly valued in vegetarian cooking. [11] Kombu is a key component of miso soup. The savory flavor of sugar kelp comes from free amino acids like glutamate. Monosodium glutamate was first isolated from Saccharina. [12] Sugar kelp gets its name due to it containing the sugar alcohol mannitol which is extracted from it to be used as a sugar substitute, especially for chewing gum. [13]

Threats

In 2004, scientists reported a loss in sugar kelp of up to 80% at Skagerrak and 40% at the West coast of Norway. [2] [14] [15] The reasons for this loss are not fully understood, but the increase in ocean temperature, high levels of nutrients and the reduction in animal species feeding off the filamentous algae are suggested as the most likely reasons. [16]

Wakame(Undaria pinnatifida) is a species of kelp native to cold, temperate coasts of the northwest Pacific Ocean. As an edible seaweed, it has a subtly sweet, but distinctive and strong flavour and satiny texture. It is most often served in soups and salads.

<i>Alaria esculenta</i> Edible seaweed

Alaria esculenta is an edible seaweed, also known as dabberlocks or badderlocks, or winged kelp, and occasionally as Atlantic Wakame. It is a traditional food along the coasts of the far north Atlantic Ocean. It may be eaten fresh or cooked in Greenland, Iceland, Scotland and Ireland. It is the only one of twelve species of Alaria to occur in both Ireland and in Great Britain.

<i>Laminaria</i> Genus of algae

Laminaria is a genus of brown seaweed in the order Laminariales (kelp), comprising 31 species native to the north Atlantic and northern Pacific Oceans. This economically important genus is characterized by long, leathery laminae and relatively large size. Some species are called Devil's apron, due to their shape, or sea colander, due to the perforations present on the lamina. Others are referred to as tangle. Laminaria form a habitat for many fish and invertebrates.

<i>Macrocystis</i> Genus of large brown algae

Macrocystis is a monospecific genus of kelp with all species now synonymous with Macrocystis pyrifera. It is commonly known as giant kelp or bladder kelp. This genus contains the largest of all the Phaeophyceae or brown algae. Macrocystis has pneumatocysts at the base of its blades. Sporophytes are perennial and the individual may live for up to three years; stipes/fronds within a whole individual undergo senescence, where each frond may persist for approximately 100 days. The genus is found widely in subtropical, temperate, and sub-Antarctic oceans of the Southern Hemisphere and in the northeast Pacific from Baja California to Sitka, Alaska. Macrocystis is often a major component of temperate kelp forests.

Fucoidan is a long chain sulfated polysaccharide found in various species of brown algae. Commercially available fucoidan is commonly extracted from the seaweed species Fucus vesiculosus (wracks), Cladosiphon okamuranus, Laminaria japonica and Undaria pinnatifida (wakame). Variant forms of fucoidan have also been found in animal species, including the sea cucumber.

<span class="mw-page-title-main">Pacific herring</span> Species of fish

The Pacific herring is a species of the herring family associated with the Pacific Ocean environment of North America and northeast Asia. It is a silvery fish with unspined fins and a deeply forked caudal fin. The distribution is widely along the California coast from Baja California north to Alaska and the Bering Sea; in Asia the distribution is south to Japan, Korea, and China. Clupea pallasii is considered a keystone species because of its very high productivity and interactions with many predators and prey. Pacific herring spawn in variable seasons, but often in the early part of the year in intertidal and sub-tidal environments, commonly on eelgrass, seaweed or other submerged vegetation; however, they do not die after spawning, but can breed in successive years. According to government sources, the Pacific herring fishery collapsed in the year 1993, and is slowly recovering to commercial viability in several North American stock areas. The species is named for Peter Simon Pallas, a noted German naturalist and explorer.

Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of Rhodophyta (red), Phaeophyta (brown) and Chlorophyta (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon and producing at least 50% of Earth's oxygen.

Saccharina japonica is a marine species of the Phaeophyceae class, a type of kelp or seaweed, which is extensively cultivated on ropes between the seas of China, Japan and Korea. It has the common name sweet kelp. It is widely eaten in East Asia. A commercially important species, S. japonica is also called ma-konbu (真昆布) in Japanese, dasima (다시마) in Korean and hǎidài (海带) in Chinese. Large harvests are produced by rope cultivation which is a simple method of growing seaweeds by attaching them to floating ropes in the ocean.
