  2. Kelp - Wikipedia

    en.wikipedia.org/wiki/Kelp

    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 ...

  4. Kelp forest - Wikipedia

    en.wikipedia.org/wiki/Kelp_forest

    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 ]

  5. Aquaculture of giant kelp - Wikipedia

    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 ...

    Includes freshwater coral reefs: 2,000 [21] 0.28 [22] 0.56 algal beds: 2,000 ... giant kelp (Macrocystis spp.) can grow as much as 30-60 centimetres vertically per day.

  7. Aquaculture - Wikipedia

    en.wikipedia.org/wiki/Aquaculture

    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.

  8. Durvillaea - Wikipedia

    en.wikipedia.org/wiki/Durvillaea

    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]

  9. Nereocystis - Wikipedia

    en.wikipedia.org/wiki/Nereocystis

    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.
