Seasonal variation in metazoan parasites of Trichiurus lepturus (Perciformes: Trichiuridae) of Rio de Janeiro, Brazil

Abstract: This work aimed to study the temporal variation of metazoan parasites of Trichiurus lepturus from the coastal zone of Rio de Janeiro, Brazil. Between July 2006 and June 2007, there were four seasonal quarterly samples of 30 specimens of T. lepturus. In addition to a group composed of anisakid larvae, we collected a total of 14 species of metazoan parasites: five digenean; five monogenean, two cestode larvae, one acanthocephalan larvae; and one copepod. With the exception of Lecithochirium microstomum and Lecit… Show more

“…Thus, temporal variations in the availability of food items may have repercussions on the parasite fauna of P. pagrus, whereas the abundance and prevalence of parasites with complex life cycles depends directly on the free-living fauna (Campbell et al, 1980;Campbell, 1983). Similar results about seasonality was reported by Carvalho and Luque (2011), composition and structure of parasite communities of Trichiurus lepturus as consequence of environmental changes and upwelling, as well as behavioral and physiological changes in host (increase in feeding and reproduction) led to immediate changes. In rainy season (spring, summer), concentrates the upwelling phenomena, breeding and spawning of P. pagrus possible responsibles for differences at parasite community in these periods.…”

“…Studies related with the population and community ecology of fi sh parasites are carry out in order to determine their natural modifi cations, including both biotic and abiotic factors of the host-parasite system that affect its dynamics (Díaz & George-Nascimento, 2002). Processes such as variations in temperature and other abiotic factors, the abundance of intermediate hosts, changes in abundance, reproductive behaviour and diet of defi nitive hosts and factors related to host immunity have been suggested to infl uence the seasonal variation in communities of parasites of marine fi sh in tropical regions (Carvalho & Luque, 2011;Soares et al, 2014).…”

“…Several biotic and abiotic factors are important determinants of parasite community species richness and diversity (Carvalho & Luque, ; Henriquez & Gonzalez, ; Luque et al, ; Poulin, ; Timi & Poulin, ). The present PCA results (Figure ) strongly suggest that interannual variations in local environmental factors (i.e., temperature, salinity, climate season, and ENSO index) had a substantial effect on parasite infracommunity structure.…”
