“…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).…”

SummaryA study of seasonal variation of metazoan parasite community of Pagrus pagrus was conducted between January and December 2012. Two hundred forty specimens of Pagrus pagrus were collected in four seasons (autumn and winter in dry season and spring and summer in rainy season) from off the state of Rio de Janeiro, Brazil. Twenty one species of metazoan parasites were found, with larvae of Hysterothylacium sp. being the dominant species. The highest values of prevalence and abundance was during the rainy season with peak prevalence of monogeneans and nematodes, period of action of the South Atlantic Central Waters (SACW) and reproductive activity of the host, suggesting that the sasonal variation in the parasites community was infl uenced for these phenomena.

“…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.…”

Marine parasite communities can exhibit temporal and spatial changes in response to seasonal and local variations in several biotic and abiotic environmental factors. Limited attention has been given to the influence of abiotic factors, so their effects on parasite community structure remain unclear. A total of 496 specimens of Euthynnus lineatus were collected over a 7-year period (2012-2018) from Acapulco Bay, Mexico. Their parasite communities were analyzed to determine if they experience interannual variations due to local biotic and abiotic factors. Thirty-three metazoan parasite species were recovered and identified: four species of Monogenea (adults); 16 of Digenea (one larvae and 15 adults); two of Acanthocephala (adults); two of Cestoda (larvae); three of Nematoda (two larvae and one adult); and six of Crustacea (three Copepoda, and three Isopoda). Species richness was greatest among the digeneans, which represented 48% of the total species recovered, followed by the crustaceans (19% of total species). Species richness at the component community level (14-24 species) was similar to reported richness in other small tuna species. The component communities and infracommunities of E. lineatus exhibited a similar pattern: high species richness and diversity, and numerical dominance by a single species, mainly by one of the didymozoids Allopseudocolocyntotrema claviforme or Pseudocolocyntotrema yaito. Parasite community structure and species composition varied among sampling years. Variations were possibly caused by a combination of abiotic and biotic factors which generated notable changes in the infection levels of several component species during the study period. These communities may therefore be unpredictable in terms of structure and species composition, as has been suggested for other communities of marine parasites.

Materials and MethodsThe list of parasitic crustaceans of fishes in Brazil was based on extensive search of published records. This bibliographic review of the crustacean species reported from fishes in Brazilian waters was complemented with information from the Zoological Record, Biological Abstracts, Web of Knowledge, Google Scholar, Aquatic Sciences and Fisheries Abstracts, Biological and Agricultural Index Plus and the Scopus. Data were compiled until March, 2013. In the case of parasitic copepods, only information not presented in the checklist of Copepoda parasites of fishes from Brazil by Luque and Tavares (2007) was included. The number of parasitic associations was calculated from the sum of the richness of species of parasites on each host species.The checklist follows the classification and systematic arrangement proposed by Boxshall and Halsey (2004) for Copepoda, and Young (1998) and Martin and Davis (2001) for other crustacean groups.The species of crustaceans are arranged according to taxonomic categories, within which the species are presented in alphabetical order, followed by hosts (specific name), site of infection, habitat, localities and references (between parentheses, in chronological order). In addition, the checklist also includes crustacean species identified only at the genus level and undetermined species. Crustacean names presented in the checklist follow the most recent taxonomic literature, but validity of individual taxa or reliability of their records was not critically examined by the present authors. Host species were arranged in taxonomic and then alphabetical order.The key to identification of the genera of parasitic crustaceans from fishes in Brazil has been produced on the basis of those by Delaney
