Mediterranean monk seal

The Mediterranean monk seal (lat. Monachus monachus) is a mammal belonging to the order Carnivora and the family Phocidae. While not a conventional agricultural pest, in the context of coastal farming and aquaculture, it is recognized as a significant factor affecting the structural integrity and operational efficiency of farms.

The species primarily impacts aquaculture operations by interacting with infrastructure located in coastal waters. These interactions often involve the accidental or deliberate damage of fish nets, cages, and floating enclosures, which are essential components of modern marine farming operations.

The biology of the species revolves around a strict reliance on coastal habitats and caves. Their foraging behavior and curiosity often bring them into direct contact with aquaculture facilities, where the density of fish populations acts as an attractant, leading to potential entanglement or equipment destruction.

The harmful impact is manifested through the mechanical destruction of containment systems. This damage leads to the loss of stocked resources and necessitates frequent, costly maintenance of agricultural equipment, which disrupts the normal cycle of production in coastal farms.

Protection strategies are centered on non-lethal deterrents to ensure the conservation of the species while protecting agricultural assets. Key methods include:

• Deployment of high-tensile, shark-proof netting and reinforced cage materials.
• Implementation of acoustic deterrent devices that discourage presence without harming the animals.
• Proactive monitoring systems to detect the approach of seals towards farm sites.
• Strict management of organic waste to minimize the lure of farmed fish at aquaculture installations.
