NEW BEDFORD — NOAA scientists have found more evidence that not only are fish migrating toward colder waters, the specific zooplankton on which they feed has moved along with them.
Kevin Friedman and his colleagues at the Northeast Fisheries Science Center said that changing water temperatures and current patterns "have profoundly affected key Northeast U.S. Continental shelf zooplankton species in recent decades, and may be influencing the recovery of Atlantic cod and other fish stocks in the region."
Zooplankton species critical for the survival of Atlantic cod larvae have thinned out in the same areas where Atlantic cod have struggled to rebuild, the study found.
"Temperature is a governing factor in the growth, reproduction and distribution of marine organisms. Shifting temperature distributions, whether triggered by natural or human factors, can cause the redistribution of plankton communities on regional and basin-wide scales," said Friedland.

NMFS recently released a draft action plan for fish discard and release mortality science, creating a list of actions that they hope can better inform fisheries.
We know that fishermen have to deal with bycatch by discarding or releasing unwanted catch overboard, but there is a data gap regarding how those fish survive.Read more...
A new study has identified a set of features common to all ocean ecosystems that provide a visual diagnosis of the health of the underwater environment coastal communities rely on.
Together, the features detail cumulative effects of threats -- such as overfishing, pollution, and invasive species, allowing responders to act faster to increase ocean resiliency and sustainability.Read more...
