Sometimes seaweed farmers cut down mangroves to use as stakes for their ropes. Mwanaisha holds up a healthy clump of seaweed. Two decades ago, seaweed farmers roamed Paje. Among algal fuels' attractive characteristics are that they can be grown with minimal impact on fresh water resources,   can be produced using saline and wastewater , have a high flash point ,  and are biodegradable and relatively harmless to the environment if spilled.
Mwanaisha holds up a healthy clump of seaweed. Despite the multifold promise of kelp, not everyone is on board with seaweed aquaculture. Microscopic flagellated spores are released from sorus tissue collected from adult plants and seeded onto string wrapped around a segment of pvc pipe. There has been considerable attention to how large-scale seaweed cultivation in the open ocean can act as a form of carbon sequestration to mitigate climate change.
The nutrients from the river would help the seaweed to grow. Kappa-carrageenan has one sulfate group per disaccharide, iota-carrageenan has two, and lambda-carrageenan has three. The seeded rope is suspended feet below the surface of the water between two moorings, and the kelp grows naturally throughout the winter.

Mwanaisha Makame and Mashavu Rum, who have been farming seaweed on beautiful Zanzibar island for 20 years, wade through the low tide to their farm. It also packs a protein- and nutrient-rich punch. As of , a number of successful trials have taken place in Hawaii, the Philippines, Puerto Rico and Tasmania. These include essential shoreline protection through the dissipation of wave energy, especially important to mangrove coasts. Nutrient bioextraction also called bioharvesting is the practice of farming and harvesting shellfish and seaweed to remove nitrogen and other nutrients from natural water bodies. As for the farmers, they are happy to have work they can rely on. Notably, Tim Flannery has highlighted how growing seaweeds in the open ocean, facilitated by artificial upwelling and substrate, can enable carbon sequestration if seaweeds are sunk below a depth of one kilometer. The high demand for seaweed production provides plentiful opportunities and work for the local community. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane.
The DMR requires a lease or license for any cultivation activity that takes place in marine coastal waters. This effectively doubled the production. Farming may be beneficial by increasing the production of herbivorous fishes and shellfish in the area.
Our coastal waters are a public resource, and managed by the state through the DMR. IC invests in private equity infrastructure assets globally focused primarily on solar energy, power generation and distribution, internet infrastructure and real estate. Pinterest Baines is among 19 veteran lobstermen along the Maine coast who are applying their hard-earned expertise to kelp farming. A number of academic studies have demonstrated that nearshore seaweed forests constitute a source of blue carbon , as seaweed detritus is carried by wave currents into the middle and deep ocean thereby sequestering carbon.
