Ringed seal

The ringed seal (Phoca hispida) belongs to the order Carnivora and the family Phocidae. While not a typical agricultural pest that consumes crops, it poses unique challenges for coastal farming operations in Arctic regions where agricultural infrastructure often overlaps with seal habitats and migratory routes.

The biology of the ringed seal is deeply tied to sea ice, which is essential for breeding and molting. Their development cycle is characterized by seasonal migration and high site fidelity. When natural prey populations fluctuate, these seals have been observed moving closer to shore, bringing them into potential conflict with human-managed coastal zones.

The damage caused by these mammals is primarily structural rather than horticultural. They can compromise fishing nets, small-scale aquaculture enclosures, and coastal barriers, which are vital for integrating aquaculture with broader agricultural practices. Their presence on haul-out sites also risks trampling sensitive coastal vegetation used for livestock grazing.

From an agronomic perspective, the harmfulness of the ringed seal is viewed as a disruption of local ecological balance and property integrity. By destroying bank stabilization materials or grazing land, they accelerate soil degradation in sensitive northern environments, indirectly affecting the productivity of local agricultural inputs.

Mitigation strategies focus on non-lethal deterrents to protect infrastructure and property. Recommended measures include:

• Deployment of acoustic deterrent devices (ADDs) to discourage presence.
• Utilization of reinforced perimeter fencing to prevent inland access.
• Strategic placement of visual markers to disrupt resting areas near high-value sites.
• Coordinated monitoring programs to alert farmers of seal migration periods.
