The glowing algae is suffocating sea life.
DFO documents reveal treatment failures and inability to protect migrating salmon.
Environmentalists often decry the loss of species diversity in rivers that have been dammed. But while some species lose when we meddle with rivers, others win, sometimes in dramatic and ways.
From African waters to China and back again, over half the fish on Nigerian tables is imported
Two summers ago, federal scientists discovered something shocking: The Northern Bering Sea was teeming with cod and pollock. Those two commercially valuable species had never been found in such large huge numbers that far north.
King salmon fishing in Alaska is political — but for those who can’t do it this summer, it’s also personal.
Scientists have identified a spike in ‘vagrant’ species of fish including damselfish, wrasse and triggerfish
The Ranavirus virus has been found in a turtle in Hamilton's Cootes Paradise wetland. It generally leads to organ failure and death within four weeks.
March becomes the hundredth month in a row with temperatures above normal. "It is unique and shows how fast climate change is happening in the Arctic," says climate scientist Ketil Isaksen at the Meteorological Institute (MET).
Recent storms have destroyed the progress made in ice formation endangering coastal habitats and fishing practices.
Warmer seas have led the fishery to move 300 kilometers further northeast - towards the North Pole. At the same time, cruising traffic in the outlying sea areas is increasing.
Fish provide a vital source of protein for over half the world's population, with over 56 million people employed by or subsisting on fisheries. But climate change is beginning to disrupt the complex, interconnected systems that underpin this major source of food.
Fish populations are declining as oceans warm, putting a key source of food and income at risk for millions of people, according to new research.
The survey started in 1971 as a review of commercially important fish like cod and halibut, but has grown into an annual scientific assessment of all sea life hauled up from the deep.
Chalky meat is not dangerous to humans but is not desirable and thus costs the fishermen at the dock.
After years of hearing concerns from fishermen about the prevalence of “chalky” halibut, the International Pacific Halibut Commission is planning an investigation.
A new study has documented unexpected consequences following the decline of great white sharks from an area off South Africa. The study found that the disappearance of great whites has led to the emergence of sevengill sharks, a top predator from a different habitat. A living fossil, sevengill sharks closely resemble relatives from the Jurassic period, unique for having seven gills instead of the typical five in most other sharks.
If the trend of reduced ice on the world's lakes continues at its current pace, the Canadian tradition of shinny could become a thing of the past, according to new research.
Greenhouse gas emissions provide extreme warming on Svalbard.
The fishing communities of Saugeen First Nation and Chippewas of Nawash are finding higher winds and warmer temperatures are affecting populations of lake whitefish in Lake Huron and Georgian Bay, which many rely on for their livelihoods.
