Abstract
This study evaluated the parasite fauna on the gills of spotted goatfish Pseudupeneus maculatus captured in the dry and rainy seasons in the coast of the State of Pernambuco, Brazil. Eight parasite species were identified belonging to the following taxa: Monogenea (Haliotrema caraïbensis, Haliotrema caballeroi and Haliotrema golvani); Crustacea (Rocinela signata, Hamaticolax scutigerulus and Caligidae gen. sp.) and Cestoda (Nybelinia indica and Pseudolacistorhynchus noodti). The most prevalent parasites were: Monogenea (100%), H. scutigerulus (35%), N. indica (11.7%), R. signata (8.3%), Caligidae gen. sp. (3.33%) and P. noodti (0.83%). Values of infestation are compared to other studies, and the uncommon occurrence of Trypanorhyncha on the gills suggests that the spotted goatfish could be an intermediate host for the parasite.
Highlights
The spotted goatfish Pseudupeneus maculatus (Bloch, 1793) is a marine demersal fish found in coral reefs, foraging mixed substrates of sand, gravel and rock (Krajewski et al, 2006; Sazima et al, 2006)
A total of 120 specimens of P. maculatus (10 fish per month), with 140.2±45.2 (47.5 to 262.1) g and 21.5±2.1 (16 to 27) cm total length were analyzed for parasites
Haliotrema caballeroi presented the highest values of mean intensity and mean abundance
Summary
The spotted goatfish Pseudupeneus maculatus (Bloch, 1793) is a marine demersal fish found in coral reefs, foraging mixed substrates of sand, gravel and rock (Krajewski et al, 2006; Sazima et al, 2006). It occurs in the West Atlantic, from Bermudas through New Jersey to the State of Santa Catarina, South Brazil (Hostim-Silva et al, 2006). It is common along the Brazilian littoral and extremely important for fishery in the State of Pernambuco (Santana et al, 2006; Lima et al, 2008).
