Sea turtle bycatch in commercial fishing operations causes significant mortality and injury, with turtle excluder devices and circle hooks offering proven mitigation tools.
Sea turtles caught in fishing gear may drown if unable to surface, or sustain hook injuries to flippers, throat, and digestive tract that cause prolonged suffering and secondary infection. Entanglement in ghost fishing gear - lost nets and lines - is a slow death by drowning or progressive injury. Turtles that are released alive but have ingested hooks require veterinary intervention to prevent internal damage from hook migration.
