Wastewater-borne DNA reveals endangered species in fish markets

Despite protective measures being in place, endangered fish species are regularly caught then sold in open markets. And while visually searching them out can be difficult, a new technology could more easily allow authorities to know which species are b… Continue reading Wastewater-borne DNA reveals endangered species in fish markets

Study suggests eating salmon-feed fish, instead of farmed salmon

One of the great ironies of salmon farming lies in the fact that even though the salmon themselves aren’t wild-caught, their feed is partially made up of smaller fish that are. According to new research, it would be ecologically better if we just ate t… Continue reading Study suggests eating salmon-feed fish, instead of farmed salmon

Biohybrid fish powered by beating human heart cells swims for 100 days

Researchers at Harvard and Emory University have created a biohybrid fish out of human heart muscle cells that can swim autonomously for months at a time as the cells beat. The project is a quirky sidestep on the way to eventually growing new functioni… Continue reading Biohybrid fish powered by beating human heart cells swims for 100 days

Study suggests that most fishes communicate with sound

We generally don’t think of fish as being a vocal bunch – after all, anglers don’t typically use “fish calls” to lure them in. According to a new study, however, approximately two-thirds of all fish species probably use sound to communicate.Continue Re… Continue reading Study suggests that most fishes communicate with sound

“Largest-ever” fish breeding colony may contain up to 60 million nests

Based on the nesting density of the surveyed area, and the nature of the surrounding seafloor, it is estimated that the colony is made up of approximately 60 million active nests

German scientists have announced the discovery of what is claimed to be the world’s largest fish breeding area known to date. Described as a globally unique ecosystem, it consists of tens of millions of icefish nests on the Antarctic sea floor.

Live fish brain study reveals surprises about where and how memories form

Scientists at the University of Southern California (USC) have managed to image the formation of memories inside the brains of live fish in real time. And the results were intriguing – synapses were seen forming in one part of the brain while disappear… Continue reading Live fish brain study reveals surprises about where and how memories form
