Officials concerned about Asian carp invading Lake Michigan tributaries are breathing a sigh of relief this week, after no new evidence of invasion was uncovered. Experts are now saying that initial DNA evidence discovered earlier this month was likely just a false alarm.
It may sound inconsequential, but sand and fine sediment from activates like sea-floor dredging and natural flood plumes can have a destructive impact on aquatic life. Now researchers are saying that silty deposits can even have a stunning impact on fish, extending the time required for the development of their larvae.
Researchers have long known that fish can used their fins for more than just locomotion. Display is a common use for elaborate fins and coloring, used to attract mates or even ward off or hide from predators. Now a new study of male bluefin killifish shows that their display fins are also used to communicate specific things.
You may be familiar with the idea that the young are the legacy and backbone of any community, leaving the old to grow fat and retire without a care in the world. It would be nice to think that this romantic concept applies to animal populations too. However, researchers are arguing that this is just not the case. Fisheries are extremely dependent on their old, slow, but still fertile females to keep populations up.
Past research has said that up to 42 percent of all treated cases of depression do not respond to antidepressants, although it has remained largely unclear why. Now researchers have found that diet can impact how a patient responds to their medication, where fish consumption can help.
Fish just want to have fun, according to a University of Tennessee, Knoxville, study that finds even fish "play."
About 385 million years ago, a pair of ancient Scottish fish did a jig that was somewhat like square dancing, and now scientists are saying this was actually the awkward origin of sex.
Rock gobies are masters of camouflage, able to change both their color and brightness within a minute, new research shows.
A potentially deadly fungus is sweeping through a river in Montana, trashing the immune systems of local trout and making them increasingly susceptible to other illnesses. Local experts are worried that this could disrupt future populations in the area, as the fungus is disrupting spawning season.
You've likely been hearing how our oceans' biodiversity is dwindling. Now a recent study shows that that this can impact local fisheries as well. That's a nightmare for not only fishermen and ecologists, but health experts too, who have been saying for years that the average person needs to consume more fish in their regular diet.
A recent study of fish and their reflections has revealed that they are not as gullible as researchers have long thought, potentially undermining the results of many past studies of aggression.
One of the most intense daily migrations occurs not across land or sea, but vertical to it. Countless small animals travel between the ocean's surface to the lightless depths of the deep sea each day. However, researchers have never investigated how this unusual migration impacts our oceans, until now.
As climate change causes oceans to warm, tropical waters are getting far too hot for fish to handle, forcing hoards of marine fish and invertebrates to take to the poles, according to a new study.
Going up? For now, endangered salmon populations on the White River can't go anywhere, but officials from the NOAA are telling the Army Corps of Engineers that river dam operations in the Washington state region must be improved to accommodate for the struggling fish.
Researchers recently put their ears to the sea, and were surprised at what they heard. In the first instance of this officially recorded and studied, scientists have found that fish larvae produce specific sounds that could help them maintain group cohesion even while in the dark.
