Abstract
Laysan albatrosses (Diomedea immutabilis) are among the most prominent bird species which interact with commercial fisheries in the North Pacific. They are attracted to fishing nets and vessels and feed extensively on animals caught in nets, waste fish, offal, and refuse discarded from vessels. Approximately 17,500 individuals were killed in the five major high seas driftnet fisheries in 1990. Laysan albatross numbers are still increasing after being decimated in the early 1900's. Mortality in the high seas driftnet fisheries is reducing the recover rate by an estimated 0.4 to 1.6% per year depending on the intrinsic growth rate of the population. The impact of the fisheries is thought to be more severe on the less abundant black-footed albatross (Diomedea nigripes) which is also increasing but at a lower rate. No driftnet mortalities have been reported for the short-tailed albatross (Diomedea albatrus).
