Scientists recently unveiled a unique new method for counting stocks of threatened fish — eavesdropping on their love calls when the fish gather in massive mating throngs. Using underwater microphones and mathematical models, researchers from the US and Mexico were able to estimate population numbers for the Gulf corvina, a popular eating fish from Mexico’s Gulf of California. About two million corvina gather every spring for a frenzied breeding session in a shallow estuary of the Colorado River Delta — bringing the entire adult population to an area less than 1% of its usual home range.
