CHICAGO— Every year, thousands of spills release crude oil into the ocean. Some spills are tiny. Others can be huge. A new study now finds that wherever it occurs, that oil pollution may harm fish.

Researchers already knew that oil pollution harms heart health in hatchlings and in embryonic fish (those still in eggs). What they didn’t ...
