The period following the Second World War saw a massive increase in global fishing effort, particularly in the 1960s. However, crashes due to this overfishing began to be reflected in the world's catch trends in the 1970s, and intensified in the 1980s and 1990s. In response, the industrialized countries of the Northern Hemisphere (where overfishing-induced catch declines appeared first) moved their effort toward deeper waters, and toward the south, i.e., to the coasts off developing countries, and beyond into the southern hemisphere, all the way to Antarctica. Now, in the second decade of the 21st century, the global expansion of fisheries is completed, and the real global catch, which is much higher than officially reported, peaked in the late 1980s and is now rapidly declining. In parallel, the collateral damage to marine ecosystems and biodiversity continues to increase. Ocean warming is now adding to these, and the ways it disrupts marine ecosystems will be described, along with the transient increase in the catch of some fisheries it may generate in high latitude areas, including Alaska.
