Warming waters in Casco Bay are driving herring farther from shore 

The Gulf of Maine is warming three times faster than the average global ocean, driving some cold-water species like Atlantic herring, the preferred lobster bait — farther away from its shoreline spawning habitat earlier than usual and attracting species from warmer southern waters, including blue crab and black sea bass, a new survey found. The warmth is stressing some of Maine’s keystone fisheries, according to the Gulf of Maine Research Institute’s report on the Casco Bay ecosystem released recently. The report is the first time the institute took a longer, 10-year look at the pace of environmental changes and their effects on ecosystems close to shore. It found that warming waters related to climate change, along with human activities, ocean acidification and harmful algal blooms, are causing different behaviors in species that could hinder their ability to reproduce and thrive. more, >>CLICK TO READ<< 09:52
