Kelp have had to adapt dispersal methods that can make successful use of ocean currents. Buoyancy of certain kelp structures allows for species to disperse with the flow of water. [21] Certain kelp form kelp rafts, which can travel great distances away from the source population and colonize other areas.
It can reach 60 m (200 ft) in length and grow as rapidly as 50 cm (20 in) a day. [54] According to one study, covering 9% of the world's oceans with kelp forests could produce "sufficient biomethane to replace all of today's needs in fossil fuel energy, while removing 53 billion tons of CO 2 per year from the atmosphere, restoring pre ...
In ideal conditions, giant kelp (Macrocystis spp.) can grow as much as 30–60 cm vertically per day. Some species, such as Nereocystis , are annuals , while others such as Eisenia are perennials , living for more than 20 years. [ 19 ]
An alternative offset would be to cultivate kelp forests. Kelp can grow at 2 feet per day, 30 times faster than terrestrial plants. Planting kelp across 10% of the oceans (4.5 x the area of Australia) could provide the same offset. Additionally, the kelp would support a fish harvest of 2 megatons per year and reduce ocean acidification. Large ...

Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions and can be contrasted with commercial fishing, which is the harvesting of wild fish. [2] Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems.
Durvillaea bull kelp grow within intertidal and shallow subtidal areas, typically on rocky wave-exposed coastal sites. [13] D. antarctica and D. poha are intertidal, whereas D. willana is subtidal (to 6 m depths). [16] Intertidal species can grow at the uppermost limit of the intertidal zone if there is sufficient wave wash. [17]
Each blade can grow up to 10 m (33 ft) long, and blade growth can reach 15 cm (5.9 in) per day. Nereocystis grows in areas where Pterygophora californica also inhabits. Bull kelp will often grow on the stipe of Pterygophora , with up anywhere from 10 to 20 individuals of Nereocystis attaching to a single Pterygophora stipe.
