2. Extraction of algae and aquatic plants

Extraction of microalgae, macroalgae and aquatic plants from water with the aim of obtaining biomass and biological remediation of aquatic ecosystems.

Biomass is plant or animal material used as fuel to produce electricity or heat. Examples are wood, energy crops, and waste from forests, yards, or farms. Since biomass technically can be used as a fuel directly (e.g. wood logs), some people use the terms biomass and biofuel interchangeably. More often than not, the word biomass simply denotes the biological raw material the fuel is made of. The word biofuel is usually reserved for liquid or gaseous fuels, used for transportation. The U.S. Energy Information Administration (EIA) follows this naming practice.The IPCC (Intergovernmental Panel on Climate Change) defines bioenergy as a renewable form of energy. In 2017 the IEA (International Energy Agency) described bioenergy as the most important source of renewable energy. IEA also argues that the current rate of bioenergy deployment is well below the levels required in low carbon scenarios, and that accelerated deployment is urgently needed. Researchers have disputed that the use of forest biomass for energy is carbon neutral.

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.
