Giant kelp is common along the coast of the eastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, Australia, and New Zealand. Growth occurs with lengthening of the stipe (central stalk), and splitting of the blades. Macrocystis pyrifera Despite its appearance, it is not a plant; it is a heterokont .

Macrocystis pyrifera, commonly known as giant kelp or giant bladder kelp, is a species of kelp (large brown algae), and one of four species in the genus Macrocystis. Macrocystis integrifolia and M. pyrifera) are very similar and are differentiated by the shape of their holdfasts. (2012). The in situ nitrogen (ammonium and nitrate) uptake kinetics of Macrocystis pyrifera and the potential for M. pyrifera to be used in an integrated multi-trophic aquaculture (IMTA) approach with salmon (Oncorhynchus tshawytscha) and mussels (Perna canaliculus) was investigated in Paterson Inlet, Stewart Island, New Zealand. 313-336. Most of the study was done at two sites within Akaroa Harbour (Banks Peninsula) but ancillary sites at Tory Channel (Marlborough Sounds) were used for parts of the study.

Both the large size of the kelp and the large number of individuals significantly alter the availability of light, the flow of ocean currents, and the chemistry of the ocean water in the area where they grow. This study evaluated the effects of seawater pH on the ontogenic development of meiospores of the native kelp Macrocystis pyrifera and the invasive kelp Undaria pinnatifida, in south-eastern New Zealand. California’s central and south coasts have also seen declines in their native giant kelp (Macrocystis pyrifera). [12] Most translocation occurs to move carbon-rich photosynthate, and typically transfers material from mature regions to actively growing regions where the machinery of photosynthesis is not yet fully in place.

The primary commercial product obtained from giant kelp is alginate, but humans also harvest this species on a limited basis for use directly as food, as it is rich in iodine, potassium, and other minerals. [20][26] There is current research going into utilizing M. pyrifera as feed for other aquaculture species such as shrimps. [32], Scientists and conservationists are continuously looking into ways to restore the once heavily populated M. pyrifera to its original state. In recent years, the kelp forests have decreased dramatically throughout Japan, Chile, Korea, Australia and North America. Retrieved from, Mondragon, Jennifer & Jeff Mondragon. The kelp often grows even longer than the distance from the bottom to the surface as it will grow in a diagonal direction due to the ocean current pushing against the kelp. It is easily recognised by the gas-filled floats at the base of each frond which help to hold the kelp upright and so maximise the amount of sunlight the blades receive. Sargassum sinclairii 4. Background Method 1,2,3. Individual algae may grow to more than 45 metres (150 feet) long at a rate of as much as 60 cm (2 ft) per day.
