Extraction of microalgae, macroalgae and aquatic plants from water with the aim of obtaining biomass and biological remediation of aquatic ecosystems.
Biomass is a term used in several contexts: in the context of ecology it means living organisms, and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g. only from plants, or from plants and algae, or from plants and animals. The vast majority of biomass used for bioenergy does come from plants. Bioenergy is a type of renewable energy with potential to assist with climate change mitigation.To the Wikipedia article about biomass
When aquatic biomass is taken from the wild, it is called extraction. The extraction is in contrast to the production of aquatic biomass, e.g. in aquaculture. The extraction takes place in different sizes and techniques. Brown algae can be harvested by hand with a sickle when the water is low. Large-scale aquatic plants (e.g. waterweed) and mussels are extracted with special boats and threshing on a barrel scale.
