A groundbreaking study explores how attaching plastic bottles to fishing nets could help prevent dolphins from being caught.Researchers found that the air inside the bottles reflects sound waves, aiding dolphins' echolocation to detect nets.Trials in Brazil showed an 88% reduction in dolphin bycatch without affecting fish catches.While results were mixed in other regions like Peru and Zanzibar, the method offers a low-cost solution for fisheries.The initiative repurposes plastic waste, turning it into a tool for marine conservation.Scientists emphasize that this innovation could be widely adopted to protect coastal dolphin populations while addressing ocean pollution.Further testing is underway in Cambodia and Congo to validate its effectiveness across different environments.
