Solenocerids

In aquaculture environments, Solenoceridae can negatively impact the yield of other farmed crustaceans and mollusks. Their presence is particularly detrimental during the early growth stages of the primary crop, where competition for food and space is most intense. They are also known to scavenge and predate upon larvae and juveniles, leading to significant losses in hatchery operations.

The biology of these organisms is defined by a complex life cycle, involving several planktonic larval stages such as zoea and mysis, followed by a benthic adult phase. Their ability to bury themselves in the substrate makes them highly resilient to traditional harvesting or cleaning methods. During the night, they emerge from the substrate to forage, which is when they cause the most significant biological and structural damage.

Damage assessment reveals that Solenoceridae are not only active competitors but also opportunistic predators. Their physical activity in confined basins disturbs the bottom sediment, which can lead to changes in water chemistry and the release of harmful substances. This secondary effect is often as damaging as the direct predation, as it stresses the primary crop and leaves it vulnerable to opportunistic diseases.

Effective management and protection strategies include:

• Strict filtration systems to prevent the entry of larvae into the facility.
• Regular cleaning and sterilization of the substrate between production cycles.
• Use of nocturnal monitoring tools to detect population spikes early.
• Implementation of biological barriers and localized trapping to isolate the pest.
