Knowra Seaweed farming Seaweed farming Seaweed farming is the cultivation of marine algae in coastal or offshore waters. It supplies food, ingredients, materials, and potential biofuel feedstocks without using arable land.
Longline aquaculture : A farming method that suspends crops from horizontal ropes anchored in water. Kelp is commonly grown on seeded ropes suspended from longlines.
Nori : Edible sheets made primarily from cultivated red seaweeds in the genus Pyropia. Nori illustrates a high-value food market built around cultivated seaweed.
Blue carbon : Carbon captured and stored by coastal and marine ecosystems. Seaweed growth removes dissolved carbon, but durable storage depends on what happens to harvested biomass.
Wild seaweed harvesting : The collection of naturally growing seaweeds from shorelines or marine habitats. Farming supplies managed crops, while wild harvest depends on natural beds and can pressure them.
Seaweed farming economics : The costs, revenues, markets, and financial risks associated with cultivating seaweed. Farm viability depends on labor, gear, processing, transport, and dependable buyers.
Kelp : Large brown seaweeds in the order Laminariales that form underwater forests and are cultivated for food and materials. Kelp is a major crop in temperate seaweed farms.
Alginate : A family of polysaccharides extracted mainly from brown seaweeds and used as thickeners and gels. Farmed brown seaweeds can supply raw material for alginate production.
Eutrophication : Excess nutrient enrichment of water that can cause algal blooms and oxygen depletion. Seaweed may remove some dissolved nutrients, while farms also require careful siting and monitoring.
Finfish aquaculture : The farming of fish in freshwater or marine systems for food or other products. Unlike finfish farms, seaweed cultivation generally requires no feed inputs.
Seaweed disease : A harmful condition in seaweeds caused by pathogens, parasites, environmental stress, or their interactions. Disease outbreaks can reduce crop yields and become harder to manage as farms expand.
