Skeleton shrimps
Systematic position: Skeleton shrimps (Caprellidae) are a family of marine crustaceans belonging to the order Amphipoda. Their unique, slender body morphology allows them to inhabit diverse benthic substrates, including macroalgae, hydroids, and various anthropogenic structures placed in marine environments.

Affected cultures: While not agricultural pests in the traditional sense, they are significant pests in the aquaculture industry. They frequently colonize shellfish farms, including mussels, oysters, and scallops, as well as seaweed cultivation lines, causing substantial economic losses through competition and structural damage.
Biology and life cycle: Caprellids exhibit a specialized life cycle characterized by the absence of a planktonic larval stage. The juveniles develop within a brood pouch and emerge as miniature versions of the adults, immediately settling on the surrounding substrate. This direct development facilitates rapid population growth in confined aquaculture environments.
Damage and harmfulness: The damage is primarily attributed to dense biofouling. Large populations compete directly with cultured shellfish for phytoplankton, drastically reduce water circulation within cages, and increase the drag and weight on equipment, which can lead to structural failure during severe sea conditions.
Protection measures: Effective management involves regular mechanical cleaning of nets and ropes to remove accumulation. In industrial mariculture, farm operators often employ depth-rotation strategies, utilize eco-friendly antifouling coatings, and perform rigorous monitoring of water quality parameters to disrupt the optimal reproductive conditions for these crustaceans.
