Researchers analyze Lagrangian coherent structures in water around swimming fish
Fish may seem to glide effortlessly through the water, but the tiny ripples they leave behind as they wriggle their way along are evidence of a constant give-and-take of energy between the swimmer and its ...
Researchers describe how an approaching object triggers a flight reaction in the fish brain
Humans and animals instinctively evade rapidly approaching objects. By doing so, they avoid collisions or escape attacking predators. For this to happen, the brain must calculate the direction and speed of ...

Battle over proposed Yellowstone River dam ramps up
An escalating legal fight over a $59 million federal dam project on Montana's lower Yellowstone River could decide the fate of an endangered, dinosaur-like fish population that has been blocked from its spawning grounds for ...
Freshwater and ocean acidification stunts growth of developing pink salmon
Pink salmon that begin life in freshwater with high concentrations of carbon dioxide, which causes acidification, are smaller and may be less likely to survive, according to a new study from UBC.
Location isn't everything but timing is for certain spawning fish
The larvae of some species of reef fish appear to survive better depending on the timing of when they were spawned, according to new research from the National Institute for Mathematical and Biological Synthesis.
The nutrition behind good sperm
Males with low sperm quality probably won't get much help from dining down on fish oil supplements and a bag of carrots, recent aquatic-based research suggests.
Researchers go with the flow to help protect endangered European eel
New research led by the University of Southampton is paving the way to protect the endangered European eel as they migrate through rivers to the ocean.
Selective breeding and immunization improve fish farm yields
Fish farming, or aquaculture, began in Malaysia as early as the 1920s, with the 1990s ushering in intensive commercial production. It is a rapidly growing sector that has witnessed a growth rate of ten percent ...
End of the dinosaurs gave rise to the modern 'Age of Fishes,' researchers find
A pair of paleobiologists from Scripps Institution of Oceanography, UC San Diego have determined that the world's most numerous and diverse vertebrates – ray-finned fishes – began their ecological dominance ...
