Tubulose and compressed

Intertidal rocks, floating structures in the sea

Upper littoral and mid littoral zone of relatively calm waters

Throughout the year

Dense

Plants yellowish green in colour, up to 11 cm long; fronds profusely branched from the stalk-like base, narrow, tubular at the base and gradually expanded and compressed above with obtuse or round apices (Figs. a, b); cells in surface view squarish or elongated and thin walled (Fig. c); plants growing at greater depths or in calm waters relatively longer. E. compressa is synonym of Ulva compressa. Enteromorpha species are cultivated in Japan for edible application. The dry powder of Enteromorpha is mixed with fast food preparations and eaten in Japan and other countries

Upper mid littoral zone

November-April

Dense in selective habitats

Plants yellowish green in colour, up to 30 cm long, attached by a small, round basal disk, fronds simple or branched, tubular with cylindrical stalks below and expanding blades above, becoming flexuous, ending in an obtuse apex (Figs. a, b), some times constricted at intervals; cells polygonal in surface view. E. flexuosa is a synonym of Ulva flexuosa.

The dry powder is used in instant cup noodles in Japan. Recently its use as garnishing agent in snack foods is gaining world wide importance mainly due to availability of nourishing agents such as poly unsaturated fatty acids, minerals, vitamins, antioxidants and proteins in them

Description

Tubular and contorted

Rocks, mudflats in mangrove environment and pebbles Mid littoral zone in brackish water habitats (river estuaries) August-April

Moderate in selective habitats especially in estuarine waters Plants simple or branched, light to yellow green in colour and up to 15 cm long (Fig. a), attached by basal rhizoidal portion and later become free-floating, mature specimens often inflated at intervals giving an intestine-like appearance, contorted and irregularly constricted (Fig. b). The name of this alga is currently regarded as synonym of Ulva intestinalis.

The seaweed meal of this alga along with other green algae used as poultry feed in some countries. Annual production of this alga is about 1,400 t (dry wt) in Japan
