Tubenosed Seabirds: Procellariiformes
Conservation Status
Twenty-three of the 108 species are threatened with extinction. One species, the Guadalupe storm-petrel, has become extinct since 1600. The primary threat is the introduction of predators to the breeding islands.
Prior to 1991, drift-net fishing was allowed. This is a type of fishing in which large nets were cast onto the waters and then hauled in. Although drift-nets efficiently caught large numbers of fish with little effort, they also caught other wildlife, including dolphins and seabirds. Drift-net fisheries were believed to be responsible for the deaths of 500,000 seabirds every year. Despite the ban on drift-net fishing, thousands of procellariiforms are still killed by long-line fisheries, a method in which long, thick hooks are baited and cast out to sea; the hooks often get caught in the necks of albatrosses, and this method catches a lot of "trash" sea life, similar to drift-netting fisheries, and trawl, a bag-like net is carried along by a boat, catching everything in its wake. A 1991 study estimated that 44,000 albatrosses are killed in Japan each year by these methods.
