Mantis shrimp

Mantis shrimp (Stomatopoda) are marine crustaceans that can become significant pests in high-tech aquaculture systems and specialized plant cultivation.

They are characterized by complex, mobile eyes and a pair of highly specialized raptorial appendages used for fast and powerful strikes.

Taxonomically, they are part of the Malacostraca class. These creatures are known for their extreme durability and ability to thrive in hidden crevices within water systems.

Their biological cycle includes a planktonic larval stage, which explains how they successfully infiltrate closed-loop systems from external water sources.

While they are fascinating organisms in their natural habitat, their behavior in agricultural settings is highly destructive and requires strict management.

In aquaculture environments, mantis shrimp cause physical damage to infrastructure, including hoses, pumps, and plant support structures.

Their raptorial appendages can pierce through tubing and root systems, leading to system failure and the loss of essential nutrients.

By digging deep tunnels in substrates, they disrupt the root integrity of aquatic plants, causing stunted growth or total plant death.

They also act as aggressive predators, consuming the beneficial micro-fauna that contributes to the nutrient balance in cultivation tanks.

In large-scale operations, their burrowing activity can weaken structural components, leading to leaks and the need for expensive system repairs.

The primary sign of infestation is unexpected mechanical damage, such as puncture marks on flexible hoses or cuts on filtration screens.

Auditory evidence is common, as mantis shrimp frequently produce sharp clicking or snapping sounds by hitting surfaces with their appendages.

The presence of burrow entrances in the substrate or near the tank walls is a clear indicator that a resident population has established itself.

Wilted plants with clearly mangled root systems suggest that the pest is actively feeding or nesting in the immediate root zone.

Shed exoskeletons found within the drainage or filtration systems confirm that the creatures are growing and thriving within the infrastructure.

Installing high-quality, fine-mesh filtration at the water intake is the most effective preventative measure to block larvae from entering.

For existing infestations, using specialized baited traps is the preferred method for removing individuals without disrupting the cultivation environment.

Regular maintenance and deep cleaning of system components can eliminate potential hiding spots and force the pests out of the equipment.

In severe cases, manual inspection during low-light conditions is necessary, as these pests are primarily nocturnal and highly elusive.

• Use 50-micron mesh filters for water intake.
• Deploy commercial crustacean traps with bait.
• Perform routine audits of all hidden pipe zones.
