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 material produced by the growth of microorganisms, plants or animals. Beyond this general definition, there are differences in how the term is used and applied depending on industry or subject-matter norms. For example, it may be more narrowly defined as just plant matter, or as a combination of plant and animal matter.
