Abstract
Overexploitation of living resources and climate change are among the most obvious global-scale impacts of human society on marine ecosystems. In an age of such large-scale anthropogenic impacts, marine scientists, resource managers, and policymakers must rethink their approaches to protecting and managing marine populations and ecosystems. Conservation oceanography is an emerging field of science that incorporates the latest advances in ocean science and technology to provide resource managers and policymakers with the information they need to ensure the sustainability of the marine environment and its living resources. Here, we discuss the historical context of conservation oceanography as it applies to marine fisheries management. We then describe two projects, one focused on Atlantic bluefin tuna and the other on Pacific salmon, that illustrate the potential of new tagging and tracking technologies for transforming the science underlying fisheries management.
Highlights
During the past half century, overfishing in many parts of the global ocean has had a substantial impact on predators at or near the top of the marine food chain (Myers and Worm, 2003; Sibert et al, 2006)
Fish Tale s from Two O ce ans To illustrate some of the recent advances in conservation oceanography, we describe two ongoing projects, Tag-AGiant (TAG) in the North Atlantic and Pacific Ocean Shelf Tracking (POST) in the North Pacific
