SUMMARY:

This study describes the morphology and histology of endoparasitic helminths from marine fish of the families Sciaenidae and Trichiuridae collected at CEASA-RJ, focusing on ecological, sanitary, and taxonomic aspects. Two species of digenean trematodes (Lecithochirium monticelli, L. microstomum) and two nematodes (Anisakis spp., Dichelyne sciaenidicola) were identified. Histological analyses using hematoxylin-eosin, orcein, and Gomori’s trichrome staining revealed structural details of tegument, suckers, musculature, and reproductive organs, showing functional adaptations for attachment and survival in the host’s intestine. Anisakis larvae displayed features consistent with zoonotic L3 stages, while D. sciaenidicola showed traits of chronic infections. The findings highlight the diagnostic value of histology for parasite taxonomy and its relevance to understanding host–parasite coevolution, environmental health monitoring, and the prevention of zoonotic risks related to fish consumption
