Brazil is a tropical country with remarkably diverse marine habitats that harbour a rich diversity of fish. Only a small portion of this fish diversity has been investigated for parasites, and thus the diversity of their trematode parasites remains unexplored. Moreover, only 5 out of 184 known digenean trematode species of marine fish in Brazil have been genetically characterised. The Hemiuridae Looss, 1899 is the second most speciose trematode family in marine fishes from Brazil but, in many ways, it remains a neglected group. Forty-three trematode specimens from nine fish species were collected from the coastal zone off Rio de Janeiro, Brazil. Trematodes were found in the stomach of 14 specimens of 9 fish species belonging to 8 families (Carangidae, Clupeidae, Haemulidae, Muraenidae, Percophidae, Pinguipedidae, Trichiuridae, and Triglidae). Trematode specimens were studied using morphological and molecular genetic analyses. A total of eight hemiurid species from four genera, Ectenurus, Lecithochirium, Myosaccium, and Parahemiurus were identified. This paper reports on new host records for four species of hemiurids, adds a new record on the geographical distribution for one species, and provides the first DNA sequence data supplemented with the detailed description of morphology for five species. Phylogenetic analyses supported that the subfamily classifications of the Hemiuridae—based entirely on morphological characters—needs to be reconsidered, taking into account a wider range of information sources.

“…Some authors have reported changes in the growth of otoliths of other species collected in different coastal regions (Buttler et al, 1996;Dehghani, 2016). These variations in otolith growth could be due to differences in habitat, food availability, and physiochemical factors of the environment waters (Aydin et al, 2004;Javor et al, 2011). Furthermore, the difference in otolith growth may be related to the changes in life history between juveniles, subadults, and adults.…”

Some fish species can be used as target species and bioindicators of environmental disturbances. In this context, biological indicators such as the length, weight, and height of lapillus otoliths of the ariid species Cathorops spixii and Genidens genidens were considered bioindicators of contamination of the Cananéia-Iguape estuarinelagoon complex (CIELC) in this study. The CIELC is an estuary with spatial and temporal differences regarding its hydrobiochemical properties and this characteristic has been related to changes in biological predictors such as the otolith morphometrics of estuarine fish. Therefore, this study aimed to verify the responses of otolith dimensions to sexual and temporal changes, throughout the CIELC. In total, 163 wild catfish C. spixii and 55 G. genidens were collected during the winter period of 2009, 2017, and 2018 in the CIELC. In general, the weight and length of lapillus otoliths of C. spixii and G. genidens were good metrics adjusted to fish growth. Females of C. spixii were significantly larger than males and subadults and there were no significant differences regarding the sexual approach of G. genidens. The temporal approach showed significant differences between the years for both catfish. C. spixii sampled in 2009 and 2018 showed greater total length (TL) and total weight (TW) when compared with fish from 2014 and 2017 (p < 0.05). G. genidens collected in 2018 had greater TL and TW than the specimens sampled in the other years (p < 0.05). Otolith dimensions seem to have followed this same pattern, since females of C. spixii had higher values for otolith weight, height, and length than males and subadults (p < 0.05). The data obtained in this study can be a potential tool for application combined with other ecological analyses and conservation studies in the CIELC.

“…Many studies highlight host body size as a predictor of parasite communities (e.g., Costa et al, 2021; Lizama et al, 2005; Poulin, 1997; Poulin et al, 2011), as it is expected that the larger the host species, the greater its ability to support a greater abundance and diversity of parasites (Lehun et al, 2023; Poulin, 1999). Other studies also highlight the role of the host's diet and trophic level (e.g., Cavalcanti et al, 2023; Lehun et al, 2023; Muñoz et al, 2006; Poulin & Leung, 2011), influencing mainly endoparasites, which can be acquired through food ingestion and their transmission occurs along the trophic chain, from one level to another (Benesh et al, 2014; Poulin, 1995), migratory behavior, considering that migratory species, when dispersed in different environments, can acquire parasites from several regions, while sedentary species are more restricted to local parasites (Criscione et al, 2006; Jacobson et al, 2019; Poulin & Angeli Dutra, 2021; Shaw et al, 2018), and habitat use (e.g., Campbell et al, 1980; Cavalcanti et al, 2023).…”

Parasite diversity can be influenced by the interaction of environmental factors and host traits, however, understanding which traits can be decisive for the establishment of the parasite can provide subsidies for a better understanding of the parasite‐host relationship. In this study, we investigated whether functional traits, diet, and host phylogeny can predict the similarity of endoparasite composition of a fish assemblage in a Brazilian floodplain. Of the three evaluated components, the host's diet was the factor that presented the greatest influence on the composition and similarity of endoparasites, demonstrating the highest percentage of explanation. The functional traits and phylogeny, despite presenting significant values (unique effect and global effect), demonstrated low explainability in the composition of endoparasites. When analyzing the joint effects, all components showed significant influences. Hosts that live in the same environment that are phylogenetically related and that have a similar ecology, have a certain degree of homogeneity in their parasite assemblages and, because they are endoparasites (which are acquired trophically along the chain), diet is the main driver of parasite richness and similarity. Overall, host traits can be one of the main determinants of parasite composition, so studies that address the functional traits of the host provide a representation of local diversity and define the possible patterns of these parasite communities.This article is protected by copyright.
