Declines in yield and poleward stock redistributions  are expected to continue under climate change and increase in magnitude with atmospheric carbon  . For example, without adaptation, end-of-century losses of Bering Sea pollock yield  is likely to reach 50% under moderate  and 80% under low  mitigation scenarios, respectively . Expanding HABs, pathogens and altered ocean chemistry  will reduce yields and increase closures of fisheries along all North American coasts  . For fisheries that represent 56% of current US fishing revenue, projected annual net losses under high-emission scenarios  may reach double that of low-emission scenarios  .
