Seaweed is lifted out of the top of an algae scrubber/cultivator, to be discarded or used as food, fertilizer, or skin care. Alginates are used in industrial products such as paper coatings, adhesives, dyes, gels, explosives and in processes such as paper sizing, textile printing, hydro-mulching and drilling.
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
A very large algae bloom in Lake Erie, North America, which can be seen from space. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in fresh water or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. [1]
Meaning "seaweed gathered from the deep" referring to its habitat of growing in deep water. The species Dictyopteris australis and Dictyopteris plagiogramma were gathered as food. Dictyota (Dictyota) Limu alani: Meaning "bitter seaweed" Double-edge sargassum (Sargassum aquifolium) Limu kala: Meaning "forgiving seaweed" employed during ...
C. frigida need a constant supply of algae to feed and lay their eggs. Thus, coastal beaches with stranded seaweed are their preferred environment. The significant factors that determine the population density and spread are the age of algae, the presence or absence of high winds or storms, the rate of decay of algae, and temperature. [5]
The gas seaweed releases when it rots — hydrogen sulfide — can irritate your eyes, nose and throat. Tiny sea creatures living in the seaweed, like jellyfish and sea lice, can also cause skin ...
Asparagopsis taxiformis (red sea plume or limu kohu), formerly A. sanfordiana, [1] is a species of red algae, with cosmopolitan distribution in tropical to warm temperate waters. [2] Researchers have demonstrated that feeding ruminants a diet containing 0.2% A. taxiformis seaweed reduced their methane emissions by nearly 99 percent. [3]
There has been some investigation into the potential of seaweeds as a carbon store, and although more is needed, one study says that seaweed habitats are believed to be the most productive of all ...
