Abstract: Morphological correlates of diet were sought among 18 species of distantly related freshwater fishes from Guinea (West Africa). With regard to the percentage occurrence of six food items, the studied species could be classified into four broad trophic categories reflecting what was eaten and where: detritivores, piscivores, surface feeders and benthic invertivores. Detrivory was associated with a high relative gut length and eyes in a dorsal position; piscivory with large body and mouth size; surface feeding w… Show more

“…In general, species with greater mouth gape tend to consume larger prey (Piet 1998). Thus, as proposed by Hugueny and Pouilly (1999) mouth gape could be a good indicator of piscivory in fishes, as well as an indicator of ontogenetic shift in the feeding habits of a given species. Establishing general relations between mouth characteristics and trophic levels (and body length) for a large number of species differing in size, shape and habitat will allow us to estimate trophic level of species for which no information on their diet is available.…”

“…This becomes particularly important where ranges of environmental factors, particularly those related to temperature such as dissolved oxygen differ widely as in tropical and temperate waterways. Within a watershed, species that overlap in environmental tolerances and preferences may coexist through other differences such as morphology and behavior (Gatz 1979;Labropoulou and Eleftheriou 1997;Hugueny and Pouilly 1999;Ward-Campbell and Beamish 2005).…”

“…Several studies had established the importance of body size, shape and specific morphological measures on swimming ability (Breda et al, 2005;Cunico and Agostinho, 2006), habitat use (Motta et al, 1995;Freitas et al, 2005) and feeding behavior (Motta et al, 1995;Hugueny and Pouilly, 1999;Pouilly et al, 2003;Freitas et al, 2005;Mazzoni et al, 2010;Neves et al, 2015). In this study, we measured the ecomorphological correlates of twenty dominant fish species of Amazonian floodplain lakes (Saint-Paul et al, 2000;Siqueira-Souza and Freitas, 2004;Santos et al, 2006;Soares et al, 2007) in order to identify groups of species with specific morphological features and relate them to ecological aspects of feeding behavior and habitat preference.…”
