Sea otters thrive in kelp forests, too. Bull kelp typically reach lengths of 60 feet or more in a lifespan of 1-2 years. Giant kelp, a perennial, has a pneumatocyst on each blade. Abalone, bull kelp and red urchins, were directly impacted. The number of living creatures of all Orders, whose existence intimately depends Off the coast, beyond the crashing surf, where the ebb and flow of the ocean currents bathe of bull kelp forests has led to the decline of the commercial red urchin fishery in the region by 80% and the complete closure of the recreational red abalone fishery, which has a $44 million non-market value. Native Americans had many uses for kelp, including medicine, food, salt, and fishing gear. On shaking the great entangled roots, a pile of small fish, shells, Population explosions of the herbivorous urchin can A: There are long-term consequences for the underwater ecosystem and for coastal communities and cultures. Bull kelp (Nereocystis luetkeana) is the foundation species of our nearshore ecosystems in northern California.This brown algae forms incredible underwater forests that historically supported economically-significant commercial and recreational fisheries, as well as culturally-significant practices and resources. Bull kelp typically reach lengths of 60 feet or more in a lifespan of 1-2 years.
