Parasites of the Mutton Snapper Lutjanus analis (Perciformes: Lutjanidae) in Alagoas, Brazil

Abstract

A parasitological survey was carried out on a sample of sixty mutton snappers (Lutjanus analis) that were caught on the coast of Alagoas, northeastern Brazil. The parasite diversity and infection levels were low. The ectoparasite Rocinela signata Schioedte & Meinert, 1879 (Isopoda: Aegidae), and larvae of two endoparasites, Trypanorhyncha gen. sp. and Hysterothylacium sp. (Nematoda: Anisakidae), were detected. The significance of these parasites is discussed in the context of their transmission pathways and potential impact.

Gill metazoan parasites of the spotted goatfish Pseudupeneus maculatus (Ostheichthyes: Mullidae) from the Coast of Pernambuco, northeastern Brazil

“…This behavior associated with the monoxenic life cycle of monogenean parasites in which release eggs provided by filamentous structures (Whittington and Kearn, 1988;Grano-Maldonado et al, 2011), might have improved their transmission explaining the high prevalence rate (100%) found in this study. The species of Haliotrema herein reported were also Hermida et al, 2014). This study showed similar values of infestation when compared to other fish species.…”

“…This study showed similar values of infestation when compared to other fish species. Slightly higher prevalence in the spotted goatfish herein studied was observed in comparison to M. argentinae , lane snapper Lutjanus synagris (Cavalcanti et al, 2013), mutton snapper Lutjanus analis (Hermida et al, 2014), blue runner Caranx crysos, castin leatherjacket Oligoplites saliens and largehead hairtail Trichiurus lepturus (Carvalho-Souza et al, 2009), and the former have reported by the first time its occurrence in the Baía de Cotegipe, Bahia, Northeast Brazil. Contrarily to that observed in this study, high prevalence rates were found in Spanish mackerel Scomberomorus brasiliensis and in parrotfish Sparisoma frondosum from the Rio Grande do Norte (Lima et al, 2005;Cavalcanti et al, 2012).…”

Rocinela signata (Isopoda: Aegidae) parasitizing the gills of the spotted goatfish Pseudupeneus maculatus (Actinopterygii: Mullidae) in Northeastern Brazil

“…Isopods of the family Aegidae are temporary or facultative parasites with low host specificity (Brusca 1983). They feed on blood and are generally found associated with the gill chamber of marine fish of economic importance (Hermida et al 2014, Bunkley-Williams et al 2006. In aquaculture, for example, fish parasitized by these isopods exihibit respiratory problems, low growth rate and are more susceptible to secondary infections due to opened wounds (Bunkley- Williams and Williams Jr 1998).…”

Anisakidae Skrjabin & Karokhin, 1945 and Raphidascarididae Hartwich, 1954 nematodes in lutjanidae (pisces: perciformes) from the Brazilian Northeast Coast

“…However, several authors have reported the presence of these parasites in marine fish, generally in greater prevalences in comparison with other helminths (São Clemente et al, 1994;Luque, 2004;Knoff et al, 2007Knoff et al, , 2013Barros, 2012). Anisakid larvae have been reported by several authors in species of fish of economic importance such as: Anchoa tricolor, Netuma barba, Brevoortia aurea, Pagrus pagrus, Prionotus punctatus, Genypterus brasiliensis, Aluterus monoceros, Paralichthysis isoceles, Rhamdia quellen, Lophius gastrophysus, Lutjanus analis, Sardinella brasiliensis, and Selene setapinnis (Palm, 1997;São Clemente et al, 1994;Cordeiro and Luque, 2004;Bicudo et al, 2005;Knoff et al, 2007;Saad and Luque, 2009;Dias et al, 2010;Felizardo et al, 2009;La Rue et al, 2010;Saad et al, 2012;Knoff et al, 2013;Hermida et al, 2014;Moreira et al, 2015;Fontenelle et al, 2015).…”
