Nutritious value of seaweeds
Seaweed is a particularly nutritious food, which absorbs and concentrates traces of a wide variety of minerals necessary to the body’s health. Many elements may occur in seaweed – aluminium, barium, calcium, chlorine, copper, iodine, and iron, to name but a few – traces normally produced by erosion and carried to the seaweed beds by the river and sea currents. Seaweeds are also rich in vitamins: indeed, Eskimos obtain a high proportion of their bodily requirements of vitamin C from the seaweeds they eat.
The nutritive value of seaweed has long been recognized. For instance, there is a remarkably low incidence of goiter amongst the Japanese, and for that matter, amongst our Maori people, who have always eaten seaweeds, and this may well be attributed to the high iodine content of this food. Research into old Maori eating customs shows that jellies were made using seaweeds, fresh fruit and nuts, fuchsia and tutu berries, cape gooseberries, and many other fruits which either grew here naturally or were sown from seeds brought by settlers and explorers.

Various products of seaweeds
New Zealand lays claim to approximately 700 species of seaweed, some of which have no representation outside this country. Of several species grown worldwide, New Zealand also has a particularly large share. For example, it is estimated that New Zealand has some 30 species of Gigartina, a close relative of carrageen or Irish moss. These are often referred to as the New Zealand carrageenan.
The gel-forming substance called agar which can be extracted from this species gives them great commercial application in peameal, from which seameal custard is made, and in cough mixture, confectionery, cosmetics, the canning, paint, and leather industries, the manufacture of duplicating pads, and in toothpaste. In fact, during World War II, New Zealand Gigartina were sent to Australia to be used in toothpaste.

Underuse of native species
Yet although New Zealand has so many of the commercially profitable red seaweeds, several of which are a source of agar (Pterocladia, Gelidium, Chondrus, Gigartina), before 1940 relatively little use was made of them. New Zealand used to import the Northern Hemisphere Irish moss (Chondrus crispus) from England and ready-made agar from Japan.
Although the distribution of the Gigartina is confined to certain areas according to species, it is only on the east coast of the North Island that its occurrence is rare. And even then, the east coast, and the area around Hokiangna, have a considerable supply of the two species of Pterocladia from which agar is also available. Happily, New Zealand-made agar is now obtainable in health food shops.

भाग चार
Locations and features of different seaweeds
Seaweeds are divided into three classes determined by color – red, brown, and green – and each tends to live in a specific location. However, except for the unmistakable sea lettuce (Ulva), few are one color; and especially when dry, some species can change colour quite significantly – a brown one may turn quite black, or a red one appear black, brown, pink, or purple.
Identification is nevertheless facilitated by the fact that the factors which determine where a seaweed will grow are quite precise, and they, therefore, tend to occur in very well-defined zones. Although there are exceptions, the green seaweeds are mainly shallow-water algae; the browns belong to medium depths, and the reds are plants of deeper water. Flat rock surfaces near mid-level tides are the most usual habitat of sea bombs, Venus’ necklace, and most brown seaweeds.
This is also the location of the purple laver or Maori karengo, which looks rather like reddish-purple lettuce. Deep-water rocks on open coasts, exposed only at very low tide, are usually the site of bull kelp, strap weeds, and similar tough specimens.
Those species able to resist long periods of exposure to the sun and air are usually found on the upper shore, while those less able to stand such exposure occur nearer to or below the low-water mark. Radiation from the sun, the temperature level, and the length of time immersed all play a part in the zoning of seaweeds.
भाग पांच
How do seaweeds reproduce and grow?
Propagation of seaweeds occurs by spores, or by fertilization of egg cells. None have roots in the usual sense; few have left, and none have flowers, fruits, or seeds. The plants absorb their nourishment through their fronds when they are surrounded by water: the base or “holdfast” of seaweeds is purely an attaching organ, not an absorbing one.
भाग छह
Why doesn’t it dry or sink?
Some of the large seaweeds maintain buoyancy with air-filled floats; others, such as bull kelp, have large cells filled with air. Some, which spend a good part of their time exposed to the air, often reduce dehydration either by having swollen stems that contain water, or they may (like Venus’ necklace) have | swollen nodules, or they may have a distinctive shape like a sea bomb.
Others, like the sea cactus, are filled with slimy fluid or have a coating of mucilage on % the surface. In some of the larger kelps, this coating is not only to keep the plant moist but also to protect it from the violent action of waves.
