Researchers developed a number of aquacultural techniques for Macrocystis cultivation in order to reverse trends of deterioration
Site Selection Criteria:
A site was selected with historical kelp beds that have declined.
Cause Of Decline:
Giant kelp (Macrocystis spp.) occurs as extensive beds along the coasts of Baja California and California, where it forms desirable habitat for fishes and invertebrates. The kelp plants are harvested and processed to produce food additives and chemicals. Many Californian kelp beds have dwindled or disappeared since 1940. About 90% of the Macrocystis population of southern California disappeared during a period of abnormally high sea surface temperatures from 1957 to 1959. Many of the former kelp areas were colonised by populations of sea urchins, preventing reestablishment.
