Carbohydrate tolerance in the fruit-eating fish Piaractus mesopotamicus (Holmberg, 1887)
(2018-03-01)
Some fish species have a limited ability to metabolize dietary carbohydrates. An important tool for understanding carbohydrate metabolism is the application of the glucose tolerance test, which can be performed orally or ...
Morphological and histochemical characterisation of the mucosa of the digestive tract in matrinxã Brycon amazonicus (Teleostei: Characiformes)
(2020-01-01)
This study describes anatomical, histological and histochemical features of the digestive tract mucosal layer of the matrinxã Brycon amazonicus, an omnivorous freshwater fish endemic from the Amazon basin. This species ...
Ichthyofauna diet changes in response to urbanization: the case of upper Paranapanema River basin (Brazil)
(2018-08-01)
Alterations in stream environments can alter fish food availability, but there is little research data related to the impacts of urbanization on fish diets in tropical streams. Thus, we sought to compare the diet of ten ...
Metals contents in two fishes of different feeding behaviour in the Lower Paraná River and Río de la Plata Estuary
(Springer, 2001-08)
Cd, Cr, Cu and Pb concentrations were measured in the water and these plus Zn were measured in the diet, muscle and liver of the detritivorous fish Prochilodus lineatus and the omnivorous fish Pterodoras granulosus at two ...
The role of riverine forests for food supply for the omnivorous fish Brycon opalinus Cuvier, 1819 (Characidae) in the Serra do Mar, Southeast Brazil
(Instituto Internacional de Ecologia, 2008-05-01)
O objetivo foi caracterizar a dieta do peixe Brycon opalinus (Characidae) sazonalmente e localmente, sendo possível determinar os itens alimentares e as relações tróficas com os ambientes aquáticos e terrestres. A área de ...

Why predation is not a controlling factor of phytoplankton in a Neotropical shallow lake: a morpho-functional perspective
(Springer, 2017-03)
This work explores the reasons why predation plays a minor role in structuring phytoplankton composition in a Neotropical shallow lake. Phytoplankton, zooplankton, and fish were sampled from a shallow lake over the course ...
Bovine plasma protein as an alternative protein source in extruded aquafeeds for Piaractus mesopotamicus (pacú) at two fattening stages
(Wiley Blackwell Publishing, Inc, 2019-11-20)
An 84‐day feeding trial was conducted to evaluate the addition of bovine plasma protein concentrate (BPP) as a full replacement of fish meal (FM) in extruded aquafeeds for the fish Piaractus mesopotamicus at two fattening ...
