Which specific types of fishing gear are frequently implicated in incidental mortality of salmon sharks?
Answer
Gillnets and longlines
The primary source of anthropogenic pressure leading to salmon shark mortality involves commercial fishing operations utilizing specific gear types where entanglement or hooking occurs frequently. The text explicitly names gillnets and longlines as the types of gear that often result in the unintentional capture of salmon sharks while targeting commercially valuable species like salmon or pollock. The high incidence of these incidental catches is a major factor driving the species toward the Near Threatened classification.
