Resumen

Caprellids are crustaceans belonging to the family Caprellidae (order Amphi-poda). Worldwide, 447 species have been described. In Peru, the species diversity of these crustaceans remains unknown. Biofouling communities serve as habitats for colonizing caprellids. The objective of this study was to describe the species richness and biomass of caprellids on biofouling communities settle on aquaculture structures of the scallop Argopecten purpuratus at Sechura Bay, northern Peru. On December 08, 2020, 3 culture lanterns, 3 refloating buoys and 3 ropes were sampled. Four species of caprellids were identified: Caprella scaura, C. penantis f. gibbosa, C. equilibra, C. penantis [sensu lato]. High abundance of C. penantis [sensu lato] was recorded in buoys. C. penantis f. gibbosa was abundant in ropes, whereas C. scaura was abundant in lanterns. A high abundance of juveniles, males, mature and im-mature females was recorded in all species, regardless of the habitat. Biofouling community was different among the culture structures. Differences were driven by the contribution to the dissimilarity of the most dominant biofouling species. This study shows that caprellids use of aquaculture structures differentially, and C. pen-antis f. gibbosa and C. penantis [sensu lato] constitute 2 new records for Peru.
