Smelling danger in the water: Schreckstoff mystery solved after 86 years
Researchers led by Yoshihiro Yoshihara at the RIKEN Center for Brain Science in Japan have solved a fishy mystery dating back to 1938: What is the schreckstoff—or alarm substance—that fish smell when their shoal-mates are injured?.....»»
Adagio in sea: Coral larvae "settle near sounds of healthy reefs"
Audio recordings of healthy reefs—an underwater chorus of fish songs and crackles from snapping shrimp—may help efforts to restore coral ecosystems harmed by climate and human impacts, scientists said Wednesday......»»
Darwin"s Galapagos island species, protected yet still at risk
Industrial fishing boats hover menacingly on the edges of Ecuador's Galapagos Marine Reserve, where schools of multicolored fish and hammerhead sharks frolic in the protected Pacific waters......»»
Diverse habitats help salmon weather unpredictable climate changes, says study
Restored salmon habitat should resemble financial portfolios, offering fish diverse options for feeding and survival so that they can weather various conditions as the climate changes, a new study shows......»»
Insights into water flow and fish passage through dams offer options for meeting energy, environmental needs
Hydropower dams provide reliable renewable energy, but they also have a direct impact on the environment, especially fish. Adjusting the amount of water spilling over a dam can help fish successfully navigate dams. But spilling more water means less.....»»
Removing Washington salmon barriers surges to $1M a day, but results are murky

Bald eagles eat prairie dogs? Researchers underscore relationship between raptors and rodents in the Great Plains
We all know that bald eagles like fish. Few of us, however, picture them soaring over grasslands seeking out prairie dog snacks. In a paper published in the Journal of Raptor Research, lead author Courtney Duchardt and co-authors make the case that p.....»»
Research reveals traits that make fish prey tasty to tuna
A cross-border science collaboration has yielded a global database that will help researchers understand how climate change is affecting ocean predators like the albacore tuna—which also happens to be an important food source for people around the.....»»
Fewer fish and more algae? Scientists seek to understand impacts of historic lack of Great Lakes ice
Michigan Tech University biologists have been observing a remote Lake Superior island's fragile wolf population every winter since 1958, but they had to cut this season's planned seven-week survey short after just two weeks......»»
Perturbations in redox status, biochemical indices, genes in the liver following fish exposure to Mancozeb
Due to the increased demand for food for the growing population, pesticides are widely used to control diseases and boost productivity. A study published in the journal Gene Expression was designed to evaluate the toxic effects of the fungicide Manco.....»»
Fewer fish, worse health: The climate effect
Over the next 25 years, reduced intake of marine food resources due to climate change will likely have a negative impact on the cardiovascular health of First Nations on Canada's Pacific coast, a new study suggests......»»
A lightweight fish pen to move farms to deeper seas
The University of Queensland has co-led a project to design a cost effective yet robust pen to expand fish farming into deeper ocean areas to help feed the growing global population. The research is published in the Journal of Marine Science and Engi.....»»
How nitrogen has been underestimated in lake ecosystems
An ecological imbalance in a lake can usually be attributed to increased nutrient inputs. This results in increased phytoplankton growth, oxygen deficiency, toxic cyanobacterial blooms and fish deaths. Until now, controls in lake management have focu.....»»
Extinctions could result as fish change foraging behavior in response to rising temperatures
Fish are changing how they search for and consume prey in warmer waters, with models suggesting that extinctions will become more likely due to this behavior change, according to a new study published in Nature Climate Change......»»
Climate change found to be reducing fish weight
Fish weight in the western North Pacific Ocean dipped in the 2010s due to warmer water limiting food supplies, according to a new study at the University of Tokyo. The work appears in Fish and Fisheries......»»
A 12 mm fish produces 140-decibel sound to communicate in turbid waters
An international research team, along with Senckenberg scientist Dr. Ralf Britz, has studied Danionella cerebrum, a small species of fish with a length of no more than 12 millimeters. Despite its diminutive size, the fish can produce sounds close to.....»»
Global dataset shows protecting fish doesn"t have to mean neglecting people
With fish stocks declining globally, more than 190 countries recently made a commitment to protect about a third of the world's oceans within "Marine Protected Areas," or MPAs by the year 2030. But these designated areas of the ocean where fishing is.....»»
Predatory fish use rapid color changes to coordinate attacks, scientists discover
Striped marlin are some of the fastest animals on the planet and one of the ocean's top predators. When hunting in groups, individual marlin will take turns attacking schools of prey fish one at a time. Now a new study reported in the journal Current.....»»
