Tiger puffer

The tiger puffer (Takifugu rubripes) belongs to the order Tetraodontiformes and the family Tetraodontidae. While primarily known for its biological features and culinary preparation, in the context of coastal industry, it acts as a significant pest that interferes with the production of marine crops.

This species causes damage mainly to maritime infrastructure rather than traditional agricultural crops. It poses a direct threat to aquaculture farms, including seaweed plantations and shellfish hatcheries, by physically destroying the enclosures that hold the products in place.

The biology of the species involves seasonal migration and a high metabolic rate, which drives their search for food. They possess strong, beak-like teeth designed to crush hard shells and structures, making them particularly destructive to the nylon meshes used in modern marine aquaculture systems.

The extent of the damage includes severed netting, broken equipment, and consumption of farmed biomass. Economic losses occur not only from the direct predation of the cultivated species but also from the high costs associated with repairing the damaged containment infrastructure.

Effective management strategies to mitigate damage involve:

• Deployment of high-tensile stainless steel mesh cages.
• Integration of ultrasonic deterrent systems to keep fish away.
• Periodic structural integrity audits of offshore farm enclosures.
• Environmental monitoring to predict peak movement periods of the species.
