Sentences with phrase «affecting marine food»

The pollution produced by carbon dioxide increases the acidity of the oceans and affects the marine food chain.

This ocean acidification makes water more corrosive, reducing the capacity of marine organisms with shells or skeletons made of calcium carbonate (such as corals, krill, oysters, clams, and crabs) to survive, grow, and reproduce, which in turn will affect the marine food chain.7

There is substantial new information that ocean acidification, rising ocean temperatures, declining sea ice, and other environmental changes are affecting the location and abundance of marine fish, including those that are commercially important, those used as food by other species, and those used for subsistence.16, 17,18,19,20,21 However, the relative importance of these potential causes of change is highly uncertain.

Ocean acidification, rising ocean temperatures, declining sea ice, and other environmental changes interact to affect the location and abundance of marine fish, including those that are commercially important, those used as food by other species, and those used for subsistence.16, 17,18,122,19,20,21 These changes have allowed some near - surface fish species such as salmon to expand their ranges northward along the Alaskan coast.124, 125,126 In addition, non-native species are invading Alaskan waters more rapidly, primarily through ships releasing ballast waters and bringing southerly species to Alaska.5, 127 These species introductions could affect marine ecosystems, including the feeding relationships of fish important to commercial and subsistence fisheries.
