Blunt-bladed hydro turbine packs fish-friendliness into a small unit

Hydroelectric turbines may indeed be a non-polluting source of electricity, but their spinning blades can nonetheless kill larger fish that are passing through. A new type is designed not to do so, while maintaining a compact form factor.Continue Readi… Continue reading Blunt-bladed hydro turbine packs fish-friendliness into a small unit

Farmer fish become first animal found domesticating another species

Human civilization wouldn’t be where it is today if we hadn’t domesticated animals to be either loyal and cuddly or dumb and tasty. Now, researchers in Australia have discovered what they claim is the very first example of an animal domesticating anoth… Continue reading Farmer fish become first animal found domesticating another species

Study supports theory that fish fins evolved from gill arches

The skeletal structure of a fish’s gill arches and paired fins are quite similar – enough so that it was once believed the fins evolved from the arches. Although that theory has since been discounted, a new study suggests it may have been right on the … Continue reading Study supports theory that fish fins evolved from gill arches

Multi-link catfish skull may hold key to better underwater robots

Even though they don’t have flexible tongues, catfish are still able to rotate captured prey within their mouths. A new understanding of how they’re able to do so could ultimately lead to more dextrous underwater robots, or other technological advances… Continue reading Multi-link catfish skull may hold key to better underwater robots

Suckerfish seen “surfing” blue whales in world-first underwater footage

Famed for their ability to latch onto larger marine animals via powerful suction cups on their heads, remora are small fish that have long fascinated scientists for the ways they seek transport and protection. A new study has delved into this behavior … Continue reading Suckerfish seen “surfing” blue whales in world-first underwater footage

If you don’t want to eat microplastics, sea bass may be the way to go

For some time now, there have been concerns that microplastic particles eaten by fish could be passed along to human seafood consumers. According to a new study, though, such may not be the case with sea bass, and possibly not with many other fish.Cont… Continue reading If you don’t want to eat microplastics, sea bass may be the way to go

Ultra-black fish that absorb 99.5% of light found in the deep ocean

Scientists have discovered ultra-black fish that absorb almost all light that hits them, allowing them to effectively hide in the deepest, darkest parts of the ocean. It appears to be a more efficient method than those used by other animals, and the fi… Continue reading Ultra-black fish that absorb 99.5% of light found in the deep ocean

Offshore wind farms could become stopover points for migrating fish

A study by the University of Maryland indicates that new offshore wind farms being constructed on the Delaware-Maryland-Virginia coastal shelf could become a stopover spot for migrating Atlantic salmon and striped bass.Continue ReadingCategory: Science… Continue reading Offshore wind farms could become stopover points for migrating fish
