A legal fight is ramping up over who should manage Alaska's dwindling salmon populations — and who gets access to them.

Landslides of wildfire ash have poisoned tens of thousands of fish in the already-imperilled Klamath Basin.

Tim Kulchyski says salmon used to be so plentiful off Vancouver Island that they would shake his Cowichan ancestors’ dugout canoes as they collided in the waters of the Salish Sea.

Residue from vehicle tires contains a chemical highly toxic to several important species of fish when it washes into streams, says new Canadian research.

Squeezing out fish stomachs and poking through intestines may be distasteful, but it’s part of a collaborative effort by researchers and recreational fishermen to save endangered salmon and divine shifts to the marine food web as climate change advances.
