It's well reported that oil spills can have a catastrophic biological and environmental impact. But to date, few studies have examined the effect of whole crude oil on senses of a marine vertebrate. A new study is the first to confirm effects on stingrays' sense of smell.

Amazonian lakes and rivers don't always have the clearest of water, so how do biologists know if piranhas are present? They can always try fishing for the things, although according to new research, listening for their "barks" may be a better way to go.

Omega-3 fatty acids have been shown to reduce inflammation, and asthma involves an inflammation of the airways. Would eating omega-3-rich fish therefore help reduce the severity of asthma? A new study indicates that the answer is likely Yes.

When fish are filleted in a seafood-processing plant, or when shrimp and shellfish are boiled, a lot of wastewater is generated. Currently, that water is discarded. An experimental new system, however, is able to draw much of the nutrients from it – and those nutrients could have several uses.

Sharks are in the ocean and piranhas are in freshwater … right? Well, it turns out that 150 million years ago, the sea was also home to a piranha-like fish known as Piranhamesodon pinnatomus. The recently-classified creature is officially the earliest known flesh-eating ray-finned fish.

Although salmon are known to be a good source of healthy omega-3 fatty acids, farmed fish typically contain much less of them than their wild counterparts. Norwegian scientists are working on a solution to that problem, in the form of fish feed made from a genetically-engineered plant.

Most water filters work by a sieve principle, in which particles that are too big to pass through a filtration membrane's pores end up collecting on it. The problem is, such filters get clogged with trapped particles. The manta ray, however, has developed a work-around.

Researchers from the California Academy of Science (CAS) have discovered a new species of fish that looks pretty hard to miss with its neon green, pink and yellow coloring.

Even though tilapia may be raised on farms, the food that they eat still contains ecologically-important fish that are caught in the ocean, depleting wild stocks. That's why Dartmouth College scientists are now looking at replacing the fishmeal in that food with existing algae meal.

Paleontologists have long wondered about the skeletons of a strange, ancient fish family called heterostracan. But now UK scientists say they’ve cracked it, declaring the 400 million-year-old fossils to be the oldest examples of bone ever found.
