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.
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 ...
Single gene controls fish brain size and intelligence
A single gene called Angiopoietin-1 (Ang-1) drives brain size and intelligence in fish according to a new study by researchers at UCL, Stockholm University and University of Helsinki.
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 ...
Bass use body's swimming muscles to suck in food
