They produce much of the oxygen we breathe and are the base of the marine food chain. Pursuit predators like sharks, box jellyfish, sunflower sea stars, and many fish like herring, cod, and tuna hunt for their prey. Haliotis iris (or blackfoot pua) is the ubiquitous New Zealand pua, the highly polished nacre of which is extremely popular as souvenirs with its striking blue, green, and purple iridescence.

The Smallest Animals in the Water: Tiny but Mighty Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates. Phytoplankton growth is often limited by the scarcity of iron in the ocean. [24] Since the mid-1990s, there have been many increasingly successful endeavors to commercially farm abalone for the purpose of consumption. These captive-bred abalone will grow and become a part of the remaining wild population, where they will hopefully improve the spawning success and be incorporated into healthy, self-sustaining populations.

Credit: Jen Burney, Aquarium of the Pacific, Celebrating the People and Partnerships Saving White Abalone, The Endangered Species Act: 50 Years of Conserving Species, Atlantic sturgeon swimming. Because they take up carbon dioxide from the atmosphere, when they die they sink they carry this atmospheric carbon to the deep sea, making phytoplankton an important actor in the climate system. For example, if that well-studied population in southern California is left alone, it will likely continue to decrease by about 10 percent per year. In California, they were most abundant at offshore islands (especially San Clemente and Santa Catalina Islands) and submerged banks (primarily Tanner and Cortes Banks).

Since 2002, the Victorian industry has seen a significant decline in catches, with the total allowable catch reduced from 1440 to 787 tonnes for the 2011/12 fishing year, due to dwindling stocks and most notably the abalone virus ganglioneuritis, which is fast-spreading and lethal to abalone stocks. Improve reproductive output and maximize survival of captive-bred animals. Wild abalone have produced few offspring since the late 1960s/early 1970s. [48], An abalone diver is normally equipped with a thick wetsuit, including a hood, bootees, and gloves, and usually also a mask, snorkel, weight belt, abalone iron, and abalone gauge. In a review of the status of white abalone in 2000, scientists estimated that the remaining wild white abalone would disappear without help from humans. Abalone shells were also traded along routes starting in southern California and reaching east of the Mississippi River. Efforts to conserve white abalone include: NOAA Fisheries and its partners have developed a captive breeding program to produce young abalone that can be reintroduced into the wild, in hopes to protect white abalone from extinction. Captive breeding efforts by current and future partners are expected to produce hundreds of thousands of animals that are ready to be reintroduced to the wild over the next 5 to 15 years.
