Marlin populations face several threats that impact their numbers and sustainability. Overfishing is one of the primary threats, as marlin are often targeted for sport fishing and commercial purposes. Bycatch in fisheries targeting other species is also a significant threat, leading to unintentional capture and mortality of marlin. Habitat degradation, including the destruction of spawning grounds and feeding areas due to coastal development and pollution, poses another risk to marlin populations. Climate change is causing shifts in ocean temperatures and currents, affecting the distribution and abundance of marlin. Additionally, the illegal trade of marlin products further endangers these majestic fish.
