Murex snails
Murex snails (Muricidae) are a diverse family of predatory sea snails classified under the order Neogastropoda. In the context of aquaculture, these organisms are recognized as significant pests that jeopardize the production of bivalve mollusks.

Murex snails
They primarily attack commercially valuable species such as mussels, oysters, and scallops. While they do not affect traditional terrestrial agriculture, their role in marine farming is highly detrimental, often causing high mortality rates in juvenile stocks.
The biology of Muricidae involves a complex life cycle, starting from planktonic larvae to sessile benthic adults. They possess specialized anatomical structures, including a powerful radula, which they use to bore through the shells of their prey to access the soft tissue inside.
The damage caused by these snails is characterized by precision drill holes in the shells of prey. Their destructiveness is substantial, as they can decimate entire populations of farmed shellfish if left unmonitored, leading to direct economic losses for farmers.
Management and control strategies involve:
- Regular inspection and cleaning of aquaculture collection lines.
- Manual removal of predatory snails from farm structures.
- Deployment of physical barriers such as fine-mesh netting to exclude snails.
- Strategic timing of harvesting to minimize exposure to peak predator activity.
