"In an ocean full of clicking shrimp and singing whales, fish are often imagined as the silent actors. Fish use motion, color, and chemicals to communicate, but they lack the iconic mewl of a cat or trill of a bird. Yet in reality, many fish chat constantly to mark their territories or find mates. And all of our noise—from seismic surveys to boat motors—is making it much more difficult for fish to hear one another."

"What do fish sound like? When Gulf Corvina breed, their mating calls could be likened to an immense, underwater roar. Now, a group of researchers have found a way to use the deafening din to save these fish from exploitation. Using underwater microphones, they’ve developed a method for converting sound recordings of the fish’s calls into precise population estimates. Those could inform more accurate catch limits, they say, that would ultimately make corvina fisheries—and others—more sustainable."
