Longlining, particularly pelagic longlining, has a significant impact on shark populations. Here's how: By-catch: Sharks are often unintentionally caught during longlining for other species. Overfishing: Some operations target sharks for their fins and meat, risking overfishing. Mortality Rate: Captured sharks can die even after release due to stress and trauma. Population Decline: Sharks' unique life cycle makes them vulnerable to rapid population drops. Trophic Cascades: As apex predators, shark decline can disrupt marine ecosystems. Regulations: Many regions now enforce rules to protect sharks from overfishing and harmful practices.
