Cladophora

"Mermaid's Hair" redirects here. For Mermaid's tresses, see Chorda filum.

Cladophora is a genus of reticulated filamentous Ulvophyceae (green algae). The genus Cladophora contains many species that are very hard to tell apart and classify, mainly because of the great variation in their appearances, which is affected by habitat, age and environmental conditions.[1] Unlike Spirogyra the filaments of Cladophora branch and it doesn't undergo conjugation. There are two multicellular stages in its life cycle - a haploid gametophyte and a diploid sporophyte - which look highly similar. The only way to tell the two stages apart is to either count their chromosomes, or examine their offspring. The haploid gametophyte produces haploid gametes by mitosis and the diploid sporophyte produces haploid spores by meiosis. The only visible difference between the gametes and spores of Cladophora is that the gametes have two flagella and the spores have four. The Cladophora species can be a major nuisance causing major alteration to benthic conditions linked particularly with increased phosphorus loading.

Laotian Mekong weed[edit]

Main article: Kaipen
Kháy phen served as an appetizer dish.

In Laos, Cladophora spp. (ໄຄ [kʰáj] "river weed" or more precisely ໄຄຫີນ [kʰáj hǐːn] "rock river weed") are commonly eaten as a delicacy and usually known in English under the name "Mekong weed". The algae grow on underwater rocks and thrive in clear spots of water in the Mekong river basin. They are harvested 1 to 5 months a year and most often eaten in dry sheets (ໄຄແຜ່ນ [kʰáj pʰɛ̄ːn] kaipen -kháy sheets-), much like Japanese nori, though much cruder in their format. Luang Prabang's speciality is dry khai with sesame, while Vang Vieng is famous for its roasted kháy sheets. They can be eaten in strips as an appetizer or with a meal. Luang Prabang kháy sheets are the most readily available form of Mekong Weed and are famous throughout the country and in the neighbouring Isaan, though difficult to find beyond Vientiane. Mekong weed can also be eaten raw, in soups, or cooked - as in a Lao amok preparation called ຫມົກໄຄ [mók kʰáj].

Invasive species[edit]

Cladophora is accused of damaging the fishing industry and shoreline property values along the Great Lakes in the United States. Quagga mussel populations have also increased tremendously in the same time frame.[2]
