Cladophora sp. K├╝tzing



These algae have profusely branched filamentous structure. The branching of Cladophora is lateral and is unique from other branched filamentous algae. The branches are not entangled by hooks but the lower portions are sometimes matted because of the adventitious rhizoids.

General Biology

Large mats of Cladophora may form in marine communities that receive terrestrial nutrient inputs such as sewage effluent or agricultural runoff. When such mats decompose, they may cause anoxia, smothering some invertebrates sharing the habitat.

Human Uses

Cultivated in Southeast Asia as a fertiliser in milkfish culture. Mature milkfish also eats the green filaments. Some species are known to have antibacterial and antiviral properties. In Korea it has been used to make and strengthen paper since the 6th century. The filaments are washed and dried before they are pressed into paper, used mainly for claaigraphy.
