Friday Squid Blogging: Squid Eating Maine Shrimp

Squid are eating Maine shrimp, causing a collapse of the ecosystem. This seems to be a result of climate change.

Maine’s shrimp fishery has been closed for nearly a decade since the stock’s collapse in 2013. Scientists are now saying a species of squid that came into the Gulf of Maine during a historic ocean heatwave the year before may have been a “major player” in the shrimp’s downturn.

In 2012, the Gulf of Maine experienced some of its warmest temperatures in decades. Within a couple of years, the cold-water-loving northern shrimp had rapidly declined and the fishery, a small but valued source of income for fishermen in the offseason, closed.

Anne Richards, a biologist at the Northeast Fisheries Science Center in Woods Hole, Massachusetts, and Margaret Hunter, a biologist with the Maine Department of Marine Resources, studied the collapse and found that it coincided with an influx of longfin squid, a major shrimp predator.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.
