Fish can’t read maps, and their eggs and larvae drift across national boundaries. Recent research shows that local problems in one fishery can affect others across wide areas.
Big storms with lots of flooding, like hurricanes Dorian and Maria, actually restore the Caribbean’s delicate balance between native and nonnative fish species, new research finds.

As the oceans warm, fish are moving to stay in temperature zones where they have evolved to live. This is helping some species, hurting others and causing a net reduction in potential catch.
A new IPCC report has called for radical changes in food production to avoid catastrophic climate change. Rice-fish farming and mixed crops could help.
Many chronic diseases increase our risk of Alzheimer’s disease. This link between our bodies and our brains means certain healthy choices could protect our cognitive function.
Californians love their coast and strongly oppose offshore drilling. Will they support converting old oil rigs to artificial reefs – a policy that benefits both marine life and oil companies?

Tiny calcified formations inside fishes’ ears can be used to trace a fish’s life history – and potentially, how climate change has affected its growth and development.
Some people argue the absence of evidence is not evidence of absence, you just need to keep looking. But there are occasions where finding no evidence is all you can do.
Protecting forests and wetlands, which absorb and store carbon, is one way to slow climate change. Scientists are proposing similar treatment for marine animals that help store carbon in the oceans.
