Turritella

Turritella is a genus of sea snails belonging to the family Turritellidae. Although most species of this genus inhabit deep marine environments, they are considered in an agronomic context as potential invasive objects capable of affecting coastal agricultural ecosystems if they infiltrate irrigation canals or appear in water sources used for crop cultivation.

Taxonomically, these organisms belong to the order Littorinimorpha and the family Turritellidae. They are recognized by their elongated, tower-like spiral shells, which serve as a primary identifying feature. Their biological role involves filtering suspended organic matter from the water column and the sediment layer.

These molluscs can pose a threat to coastal crops if they enter irrigation systems or storage ponds. The primary damage occurs through the mechanical clogging of pump filtration systems and the alteration of water chemistry, which can lead to negative impacts on the root systems of crops sensitive to changes in water quality and mineral content.

The biology of Turritella is centered on their high reproductive potential in favorable aquatic conditions. The larval stage develops within the water column, followed by settlement on the substrate. Their lifecycle is highly dependent on water salinity and temperature; therefore, in stagnant or shallow water bodies, population densities can reach levels that disrupt irrigation infrastructure.

Protection strategies focus on the rigorous monitoring of irrigation water quality. Effective management involves the installation of filtration units at the water intake points and routine mechanical cleaning of irrigation channels. The use of molluscicides in open water bodies is strictly regulated due to environmental safety concerns, making preventative infrastructure maintenance the preferred method of control.
