Title: Ecosystem-Based Management of Deep-Sea Fishes and Their Ecosystems
Author: Ellen Pikitch

Within session: The World's Last Wildlife Hunt: Deep-Sea Fisheries
Session Start/End Time: Sunday, Feb 18, 2007, 1:45 PM - 4:45 PM

The world’s largest wildlife hunt is undergoing a profound shift. Having largely eliminated most commercially desirable nearshore fish populations, commercial fishing is now seeking white-fleshed fish in ever-remoter and deeper waters. There are at least six reasons why fishing in the deep sea threatens these ecosystems: (1)they target little-studied species in Earth’s least-known ecosystem; (2) many target and nontarget species are long-lived, late-maturing, and have very low potential population recovery rate; (3) some deep-sea ecosystems, particularly seamounts, have high endemism, so even minimal fishing pressure can cause extinctions; (4) methods used to catch some deep-sea species, particularly bottom trawling, are extremely destructive; (5) under current fishery conditions it is economically rational to sequentially liquidate populations of long-lived, slow-reproducing species and move on; and (6) most deep-sea ecosystems are in international waters, which are the largest and least protected ecosystems on Earth. As marine biodiversity declines and fisheries collapse worldwide, a swelling chorus of scientists, government officials, policy experts, and conservation advocates are calling for more sustainable fishing approaches. This symposium brings together experts who will examine the impacts of deep-sea fisheries and the prospects for their sustainability.
