The US fishing and seafood sector years generated more than $200 billion in annual sales and supported 1.7 million jobs in recent years. It experienced broad declines in 2020 as a result of the COVID-19 public health crisis, according to a new NOAA Fisheries analysis released today.
Close to 5,700 lakes in the Northern Hemisphere may permanently lose ice cover this century, 179 of them in the next decade, at current greenhouse gas emissions, despite a possible polar vortex this year, researchers at York University have found. Those lakes include large bays in some of the deepest of the Great Lakes, such as Lake Superior and Lake Michigan, which could permanently become ice free by 2055.
Most of the revenues extracted from use of the world's oceans is concentrated among 100 transnational corporations. Dubbed the "Ocean 100" by researchers at Duke University and Stockholm University, these "blue economy" companies collectively generated $1.1 trillion in revenues in 2018, according to research published Wednesday in the journal Science Advances. If the group were a country, it would have the world's 16th-largest economy, roughly equivalent to the gross domestic product (GDP) of Mexico.
A new study involving the University of Maine assessed immune responses in four economically important marine mollusc species -- the blue mussel, soft-shell clam, Eastern oyster, and Atlantic jackknife clam -- and identified new biomarkers relating to changes in protein function involved in novel regulatory mechanisms of important metabolic and immunological pathways.

Second only to the spiny lobster, the queen conch is a prized delicacy long harvested for food and is revered for its beautiful shell. Conch populations have dwindled so low, creating a dire and urgent situation in ecological and economic terms. To preserve this significant molluscan fishery in the Caribbean, the world's leading expert on queen conch aquaculture has published an 80-page, step-by-step user manual that provides complete illustrations and photos of how to culture and restore the queen conch.
Mussels, oysters and scallops have the highest levels of microplastic contamination among seafood, a new study reveals.
