1. Production of aquatic biomass

Production, harvest and processing of microalgae, macroalgae, halophytes and aquatic plants in land- and water-based systems with the aim of extracting valuable aquatic biomass.

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.
