“…Thus, these species must efficiently perform both long-distance steady swimming and local unsteady swimming. Diet composition and habitat structural complexity are principal factors shaping fish morphology (most recently Foster et al, 2015;Prado et al, 2016;Restrepo-Escobar et al, 2016;Lazzarotto et al, 2017;Siqueira-Souza et al, 2017). Anatomically, relative trunk and tail lengths are related to the absolute number, size and relative distribution of vertebrae.…”

Common bream Abramis brama, roach Rutilus rutilus and their hybrids were collected in the Dobczyce Reservoir in southern Poland in 2006-2013 to study whether it is better for a hybrid individual to resemble and compete with one of its parents, or to minimize competition by having a distinctive phenotype. All hybrids were F crosses and originated predominantly (93·2%) from matings between female A. brama and male R. rutilus parents. In morphometric analyses, a newly defined coefficient, L = 2·5 (body mass) (L × body depth) , which enables forms with similar length-depth proportions but different length-mass relationships to be distinguished was used. Morphometric and meristic characteristics of the hybrids were intermediate in comparison with the parental species, with small but significant deviation towards R. rutilus in longitudinal body dimensions (trunk and tail length) and towards A. brama in body cross-sectional shape (body depth and L coefficient). This may result in a more R. rutilus like propulsion in hybrids and a more A. brama like ability to manoeuvre.

“…The diet of fish species is strongly driven by both the availability of prey items (Winemiller 1989, Wootton 1990, Luz-Agostinho et al 2008, Correa & Winemiller 2014 and the ability of predator species to capture prey (Schoener 1971, Abrams 2006. This ability is dependent on specific morphological adaptations (Adite & Winemiller 1997, Hugueny & Pouilly 1999, Pouilly et al 2003, Teixeira & Bennemann 2007, Mazzoni et al 2010, Pagotto et al 2011, Siqueira-Souza et al 2016b. The relationships between morphology and feeding behavior are addressed through an examination of ecomorphology (Wikramanayake 1990, Winemiller 1991, Teixeira & Bennemann 2007, Mazzoni et al 2010, Sampaio et al 2013.…”

“…Ecomorphological studies have shown a relationship between feeding items and mouth size or position and the type and size of their prey (Gatz Jr. 1979, Piorski et al 2005, Cochran-Biderman & Winemiller 2010, as well as between size and shape of fins and swimming or maneuverability (Keast & Webb 1966, Gatz Jr. 1979). In the Amazon basin, multiple research groups have already employed an ecomorphological analysis approach on Amazonian fish groups to elucidate the ecological relationships between feeding behavior, swimming ability, and habitat use preferences with morphology (e.g., Pouilly et al 2003, Freitas et al 2005, Siqueira-Souza et al 2016b.…”

Diet and ecomorphology of predator fish species of the Amazonian floodplain lakes

et al. 2019

Amazonian floodplain lakes host a high diversity of predatory fish which coexist and exploit the high diversity of available prey. Morphology could be the characteristic most closely associated with their preferred feeding sources (prey). However, it is unclear whether this association is direct or indirect. If it is indirect, swimming performance or preferential position in the water column could be the most evident characteristic. To examine the degree to which fish morphology of predator fish species is correlated to their dietary inputs, we compared the existence of morphological and feeding dissimilarity among eight predator species with the association between predator morphologies and preferred prey. We collected, measured, and sampled the stomach contents of fish from two lowland floodplain lakes associated with the Solimões River, Brazil, in May, August, and November of 2014. Of 187 collected fish across eight species, five species showed fish to be the most important item in their diets and three preferentially ate shrimp. Principal components analyses of ecomorphological attributes divided the species according to their ability to find the prey, swimming performance of the predator, and prey size. While there was significant distinction between the varying morphologies of predators, we were unable to distinguish between the specific diet of these species and did not find a correlation between morphology and feeding. These results are likely due to the fact that there is great abundance and diversity of available prey in the Amazonian floodplain lakes, so opportunistic feeding may be the primary foraging strategy of predator fish species living in these environments.

“…These habitats provide areas which are used by several fish species for shelter, feeding, growth and reproduction during different phases of their life cycles. The seasonal component (rainy and dry seasons) adds additional complexity to the floodplain habitat by altering the availability of these habitats to fish over the course of the year (Siqueira-Souza et al, 2017).…”

Comparison of the endoparasite fauna of Hoplias malabaricus and Hoplerythrinus unitaeniatus (Erythrinidae), sympatric hosts in the eastern Amazon region (Brazil)

SummaryHoplias malabaricus and Hoplerythrinus unitaeniatus are Erythrinidae family widely distributed in the Amazon River system of great value to both commercial and subsistence fishing for riverine populations. As such, the objective of the present study was to investigate the endoparasite communities of H. malabaricus and H. unitaeniatus of a tributary of the Amazon River in the north of Brazil. The endoparasite communities of H. unitaeniatus and H. malabaricus were taxonomically similar (85%) and consisted of Clinostomum marginatum, Contracaecum sp., Guyanema seriei seriei, Procamallanus (Spirocamallanus) inopinatus, Pseudoproleptus sp. and Gorytocephalus spectabilis, although the dominant endoparasite was C. marginatum, which was the most prevalent and abundant. All the specimens of both H. malabaricus and H. unitaeniatus were parasitized, with a total of 1237 helminths collected in the former host and 1151 helminths collected in the latter. Hoplerythrinus unitaeniatus possessed greater parasite species richness. Both hosts had an aggregate dispersion of parasites, and the abundance of C. marginatum, Contracaecum sp. and G. spectabilis correlated positively with the weight and length of the hosts. The condition factor was not affected by parasitism, but the abundance of C. marginatum and Contracaecum sp. increased when the condition factor of the hosts decreased. This is the first report of G. seriei seriei for H. malabaricus and Pseudoproleptus sp. for H. unitaeniatus.
