A deadly fish disease known as VHSv has plagued hundreds of freshwater fish in Lake Winnebago, in Wisconsin. While some older individuals have developed a resistance toward the disease, they could spread the disease to younger fish and cause another mass die-off in the future.
Beaver dams are helping restore natural ecosystems throughout the U.S. Essentially, a beaver dam blocks off water in one section of the stream, which then creates a pond or lake. Using this, researchers may have found a way to remove excess nitrogen from local estuaries.
Using a new, specialized net, a team of researchers recently collected polar cod (Boreogadus saida) from their icy homes in order to better understand the fishes' large-scale distribution and origin as well as the predators that feed on them.
Toxic stormwater has been linked to the death of coho salmon along the U.S. West Coast. Now, using a simply filtration system, researchers may be able to save them from extinction.
After making the most comprehensive study of fish species in the Salish Sea (the body of water that includes Puget Sound and the Strait of Georgia, University of Washington researchers have reported that species diversity there has increased 14 percent.
Fish extend their jaws to decrease the distance between them and their prey. This evolutionary feeding advantage is known as jaw protrusion.
Over the past five years, more than 200 new species have been found in the Eastern Himalayas and noted in scientific studies.
A recent NOAA dive in the Northwestern Hawaii Islands revealed many new and unique species living deep in the Papahanaumokuakea Marine National Monument.
Researchers from Linnaeus University closely examined migrating patterns of pike in the Baltic Sea and found that timing is the key to survival.
An alarming number of Guadalupe fur seals have died after stranding themselves along California's coast. As a result, the National Oceanic and Atmospheric Administration (NOAA) has declared an "Unusual Mortality Event" and is investigating why the marine animals are traveling so far from their natural habitats.
Aquaponic garden systems use fish feces as natural fertilizers. In return, the plants grow faster and naturally filter the water before returning it to the fish. This system ensures environmental sustainability.
Rabbitfish have exceeded researchers expectations in terms of their ability to cooperate. A new study shows that theythey use a cooperative feeding strategy where one stands guard for protection while another is feeding.
People are advised to eat increased amounts of seafood, bur almost half of it is wasted each year. Since overfishing, pollution and climate change are already impacting fish populations, scientists are examining ways to reduce waste in order to sustain future demands.
New research shows that blind cave fish (Astyanax mexicanus) evolved to conserve energy. They gave up sight and circadian rhythm to survive solely on their sense of smell and taste.
