Anyone who has looked into the soupy river and canal waters flowing through Chicago knows that even with a diver's mask and halogen light you'd be lucky to spot a sunken barge, let alone a fish that ...

Scientists report that sponges, which can filter 10,000 liters of water daily, catch DNA in their tissues as they filter-feed. This proof-of-concept study identified fish, seal, and penguin DNA in ...

SEATTLE — A new study by researchers at the University of Washington used "environmental DNA" to assess where culvert replacements helped increase fish passage. Researchers utilized a technique they ...

In 1975, scientists tried spaying a few hundred female betta fish. We all know what happens to spayed cats and dogs: They become sterile. Betta fish are different. A third of the surviving bettas ...
