Scientists are delving deep into the travels of whales—thanks to high-tech tracking devices—to try to help protect them.
(Phys.org)—Using underwater video cameras to record fish feeding on South Pacific coral reefs, scientists have found that herbivorous fish can be picky eaters – a trait that could spell trouble for endangered reef systems.
Researchers in Iceland are blaming low oxygen levels in a shallow fjord for the deaths of tens of thousands of tons of herring.
A new NOAA research report finds that both fish populations and commercial and recreational anglers have benefited from "no-take" protections in the Tortugas Ecological Reserve in the Florida Keys National Marine Sanctuary.
For social animals such as schooling fish, the loss of their numbers to human activity could eventually threaten entire populations, according to a finding that such animals rely heavily on grouping to effectively navigate ...

Despite modern designs intended to allow migratory fish to pass, hydropower dams on major Northeast U.S. waterways, including the Merrimack and Connecticut rivers, have failed to let economically important species such as ...
Salmon runs are notoriously variable: strong one year, and weak the next. New research shows that the same may be true from one century to the next.
Scientists hope to gain a better understanding of the causes of oxygen depletion among fish populations with an EU-funded project called HYPOX.
