AI Article Synopsis
- The study focused on Branchiura parasites in fish from the Araguari River, examining their distribution, interactions, and preferences based on the fish's habitat and surface type.
- Novel findings highlighted how the attachment structures of these parasites related to the fish's scaliness and body morphology.
- Out of 558 fish, 109 exhibited parasitism, showing that parasites with suction discs preferred fish with smaller or no scales, while hook-based parasites favored larger-scaled hosts.
Article Abstract
This study investigated the spatial distribution, parasite interactions, and affinities of Branchiura parasites according to macrohabitat and surface type on fish from the Araguari River, Amapá State, in the Brazilian Amazon. This study presents novel information on the interactions of branchiuran species with host fish, and how the morphology of their attachment structures is associated with different host surface morphologies, with and without scales. A total of 558 fish specimens of 26 species were collected, of which 109 fish (10 species) were parasitized by at least one branchiuran parasite; these were selected for further study. The parasites were collected from the buccal cavity, gills, fins, and integument of the host fish. Parasites with suction discs (Argulus) were mainly associated to hosts with small scales and no scales, while parasites with hooks (Dolops) were mainly associated to hosts with large scales. Overall, parasites with suction discs were more specialized per site than those with hooks.
