Persistent Threats Remain Amid Promising Mitigation Innovations

Despite expanding ranges and increased visibility, many shark populations face ongoing threats from localized declines, illegal fishing, and bycatch:

• South Australia’s Port Jackson shark populations have significantly declined in regions affected by toxic algal blooms linked to warming seas, with tagging studies revealing stark absences in impacted zones.

• Illegal fishing remains a pressing issue; for example, New Zealand authorities confiscated 23 illegally killed sharks in Porirua Harbour, highlighting enforcement gaps that jeopardize shark conservation.

• Bycatch continues to endanger sharks worldwide, stimulating rescue efforts off Manly Beach, Australia, and intensifying interactions along Florida’s coastline.

• A breakthrough from Florida researchers involves zinc-graphite shields designed to repel sharks from fishing hooks. This low-cost, simple innovation shows strong potential to reduce bycatch mortality and could be scaled globally.

Together, these realities emphasize urgent imperatives for strengthened enforcement, community engagement, and technology-driven solutions to curb shark population declines.
