A research team tracked the diets and exposures to air pollution of kids inside Baltimore homes. Children with diets high in omega-3 fatty acids seemed less vulnerable to pollution's effect on asthma.
They initially thought it was a type of fish known to swim near Santa Barbara. But by collaborating with Australian scientists, they found it was a species never before documented in North America.
Harbor seals use sensors in their whiskers to help discern predator from prey. It's all about the way the water whirls, say scientists who are now training computers to be better trackers, too.
Plus-sized mama fish have a size advantage over their petite counterparts: They can produce more eggs, and those eggs produce larger fish. It's a reminder that protecting big fish matters.
Many consumers don't yet understand the label, but grocery stores are now buying from "salmon-safe" farms, which help protect fish by banning pesticides and keeping manure out of the land's waterways.
Using historical data and estimates from deep-sea trawls that drag nets along the ocean floor, researchers estimate that millions of tons of catch have gone unreported in the last 50 years.
Historical photos show fishermen with chinooks almost as tall as they are. A century's worth of dam-building, overfishing, habitat loss and hatcheries has cut the size of the average fish in half.
The red handfish, named for hand-shaped fins on the sides of its body, doesn't really swim — it walks slowly along the seafloor. A new population of the striking creature has been found off Tasmania.
Industry trailblazers are trying to reduce the energy and resource costs of aquaculture. Possible solutions include using brewery waste, algae, insects or even carbon dioxide to feed the fish we eat.
The tribe has fished in the Pacific Northwest's Klamath River for centuries, but the Chinook have been devastated by drought, disease, dams, and a long history of habitat destruction.
New England fishers say it's been decades since they've hauled in so many tuna, and some in the industry are urging higher quotas. But some environmental groups fear the population is still imperiled.
The lack of clean water, sanctions and ISIS have all contributed to depleting the supply of fish that is salted, fire-roasted and shared by Iraqis of all sects and political persuasions.
At a ceremony at Tokyo's Akasaka palace, the president appears to grow weary of a traditional koi feeding — so he simply dumps the contents of his box of fish food. But video tells the whole tale.
The armored catfish erodes shorelines and devastates marine plants — and its numbers have exploded. So researchers, chefs and fishermen are trying to rebrand it by promoting its flavor and nutrition.
Commercial fisherman are putting off their own livelihoods to catch the farmed Atlantic salmon that broke out of their net pen in Washington state. One fisherman describes the "carnival atmosphere."
Earlier this month, thousands of Atlantic salmon escaped a net pen in Washington state, raising concerns from environmentalists and questions about farming non-native species. Here are some answers.
The invasive species have been caught mere miles from Lake Michigan. Scientists fear if they invade the lake, they could spread throughout the Great Lakes.
Because demand for seafood is rising and wild stocks are not, a hatchery owner in Canada is hoping his model of "responsible agriculture" can keep the prized fish both on the menu and in the water.
In order to investigate how eating fish affects our health as well as the oceans, author and fisherman Paul Greenberg spent a year eating fish every day.
Native cutthroat trout, an iconic part of the mountain West, thrive in cold streams. But warmer weather has allowed invaders to move in — and it's killing off the cutthroats.
New research shows the 2-inch fangblenny bites bigger fish and releases an opioid-based venom. The larger fish becomes disoriented, and the little guy gets away.
Every winter people flock to the frigid lakes of Canada and the northern U.S.A. to ice fish. According to a new study, thislow and seemingly harmless sport has some risks of injuries.
Currently, one-fourth of all fish caught globally goes to produce fishmeal and fish oil for farmed seafood, pigs and chickens. A lot of it is "food grade" and could be feeding the world's hungry.
