With Australia’s beaches and oceans covered in rubbish, Tangaroa Blue volunteers spend days trying to clean things up.
The myth of the three-second memory in fish never made sense. Some species may be able to retain specific memories for months.
Canadian supermarkets have become the first in the world to stock genetically modified fish.
Noise from boats is a 'global pollutant', distracting fish and making them unable to properly protect their young from predators.
New studies show that alarming numbers of tiny fibers from synthetic fabrics are making their way from your washing machine into aquatic animals.
As ice seasons are getting shorter around the world, we are losing ice without a deep understanding of what we are losing.
Male three-spined stickleback fish are unusual in that they build nests and provide all the parental care for the eggs, which are spawned by females, and for the developing baby fish.
Similar to factory farming, aquaculture is becoming an industrialized food system that is unsustainable and unnecessarily cruel.
Researchers have discovered a strange new species of fish which has no eyes or scales, and its skin has no pigments whatsoever. The fish lives in inaccessible subterranean streams.
Nutrient pollution emptying into seas from cities, towns and agricultural land is changing the sounds made by marine life -- and potentially upsetting navigational cues for fish and other sea creatures.
The washing of clothes is a major source of microscopic fibres within the aquatic environment.
The silvery skin of fish like herring, sardines, mackerel and tuna act like mirrors, reflecting their watery surroundings to better blend in. The effect serves as a kind of underwater invisibility cloak that helps them hide in plain sight.
Ominous background music could hinder shark conservation efforts.
Working with the fishing industry to modify what types of gear are used and when and where different species are allowed to be caught can make more of a difference than establishing new marine protected areas. Closing one area to fishing will just shift the pressure to a different area, or cause people to seek other, more environmentally harmful sources of food.
Even small and transient oil spills affect haddock larvae to such a degree that they struggle to reach adulthood.
A fish out of water might seem an extraordinary thing, but in fact it is quite a common phenomenon. The emergence of fish onto land more than 350 million years ago was a critical step in the history of life on Earth, leading to the evolution of all land vertebrates, including humans.
Toxic chemicals are accumulating in marine creatures in Earth’s deepest oceanic trenches. Crustaceans at depths of 10,000 metres contain higher concentrations of man-made chemicals than do some animals in coastal waters.
A tropical fish can tell one human face from another despite lacking a brain section that homo sapiens and other “smart” animals use for this task.
Today there is increasing concern that the accumulation of microplastic waste particles could affect the functioning of marine ecosystems, but our knowledge of the impacts of microplastic fragments on marine animals is limited. For the first time, scientists have now been able to show that development of fish is threatened by microplastic pollution.
Where fish are concerned, acidification can make low oxygen even more deadly. In coastal waters, nutrient pollution fuels the growth of algae and other organisms. As microbes, plants and animals take up oxygen through respiration, oxygen levels plummet to low levels or even zero. At the same time, acidity spikes as those same organisms release carbon dioxide.
