Abstract
Isópodes da família Cymothoidae são ectoparasitos de peixes, com baixa especificidade de hospedeiros, comumente encontrados fixados nas brânquias, boca, cavidade opercular, narinas e tegumento de ampla variedade de hospedeiros. Os danos causados são variáveis em função do grau de parasitismo e do sítio de infestação e podem provocar desconforto respiratório nos hospedeiros. O objetivo deste estudo foi relatar a ocorrência do isópode Nerocila sp. Leach, 1818 parasitando Mugil liza Valenciennes, 1836, capturada na Baía da Babitonga, estado de Santa Catarina, Brasil. Uma fêmea de 24 mm de comprimento e 11 mm de largura, contendo ovos de 1.18 ± 0.08 x 1.03 ± 0.06 mm, foi encontrada na nadadeira peitoral de M. liza.
Highlights
The Isopoda are dorsoventrally flattened crustaceans inhabiting both marine and freshwater environments (RAMESHKUMAR et al, 2016)
Other species may act as ectoparasites of fish, usually parasitizing the gills, mouth, opercular cavity, nostrils and body surface of hosts (BOWMAN; TAREEN, 1983; CHARFICHEIKHROUHA et al, 2000; RAMDANE et al, 2007)
One of the main problems associated with parasitism is the repugnant appearance of infested fish, because parasites can be seen by the naked eye; this can cause significant economic losses to fisheries (EIRAS, 2004; LIMA et al, 2013; EIRAS; CASTRO, 2016)
Summary
The Isopoda are dorsoventrally flattened crustaceans inhabiting both marine and freshwater environments (RAMESHKUMAR et al, 2016). Other species may act as ectoparasites of fish, usually parasitizing the gills, mouth, opercular cavity, nostrils and body surface of hosts (BOWMAN; TAREEN, 1983; CHARFICHEIKHROUHA et al, 2000; RAMDANE et al, 2007). Nerocila spp. can be highlighted as one of the species from Cymothoidae (Leach, 1818) and is among the parasitic isopods (BRUSCA et al, 2001).
