The Australian lungfish is a river fish native to southeastern Queensland. According to fossil records, the ancestors of this ancient fish appeared about 380 million years ago. As their name suggests, lungfish don’t just breathe with their gills, but also have a lung to supplement oxygen intake during unusual circumstances, such as when there is […]

Sometimes all it takes is a single photograph to change someone’s mind or inspire them to take action. For Catherine Collins and her husband Douglas Frantz, that was a photo of a yardstick plunged 32 inches into filth below a salmon farm near Port Mouton, Nova Scotia.
Sea lions that encountered a salmon farm near Tofino — a town on Vancouver Island, British Columbia — have been helping themselves to a fish feast for weeks. The Rant Point farm is owned by Cermaq, a company based in Oslo, Norway, that operates fish farms in Canada, Norway and Chile.
A new study has found that fish in the oceans communicate through a variety of sounds made in extraordinary ways, from moving or grinding their jaws to vibrating their bodies to snapping their tendons. Although researchers already knew fish communicated through sound, it was believed to be a rare phenomenon. The study, published in the […]
Saltwater pollution of the world’s freshwater ecosystems caused by agriculture fertilizers, road de-icing salts, mining operations and climate change is on the rise, and the current water quality guidelines in North America and Europe aren’t stringent enough to prevent it. An international study conducted by scientists from Europe and North America found that freshwater lakes […]
Pharmaceutical drugs have polluted the world’s rivers and pose “a global threat to environmental and human health,” according to a new study by the University of York. The most extensive global study to date found that among the most polluted rivers were those in Bolivia, Pakistan and Ethiopia, while rivers in the Amazon rainforest, Iceland […]
What’s around five inches, olive yellow with dark blotches and apparently no longer extinct in the state of Ohio? The answer is the longhead darter, a small-to-medium size fish which was spotted in the state for the first time since 1939, as the Ohio Division of Wildlife announced on Facebook January 6.
As climate change causes the temperatures of the world’s oceans to increase, the fish calling those warmer oceans home could become smaller, scientists say. This is due to warmer oceans having less oxygen, and bigger fish requiring more of it. This could lead to issues for the fishing industry, and to food insecurity.
