Histamine in Brazilian Foods: A Comprehensive Review of Occurrence and Risk Assessment for Intoxication and Intolerance. [PDF]

open access: yesFood Sci Nutr
Even though histamine plays an important role in human health, it has been associated with food intoxication and intolerance episodes. The most relevant, current state of knowledge regarding histamine's biochemical and health aspects is provided. Histamine levels are provided for 17 food groups, including 335 food types and 11,437 samples, allowing ...

A typical enzyme activity for glutathione conjugation indicates exposure of pacu to pollutants

open access: yesNeotropical Ichthyology, 2022
Functional enzyme assays to detect sublethal poisoning of Neotropical fish are paramount. Accordingly, we assayed a glutathione S-transferase (GST) activity in liver and kidney cytosols from Piaractus mesopotamicus injected with methyl parathion or benzo[

Redescription and Geographical Distribution of the Endangered Fish Ossubtus xinguense Jégu 1992 (Characiformes, Serrasalmidae) with Comments on Conservation of the Rheophilic Fauna of the Xingu River. [PDF]

open access: yesPLoS ONE, 2016
The monotypic species Ossubtus xinguense was originally described based on scarce material putatively divided into juveniles and adults. Ossubtus xinguense has a restricted distribution and was previously known only from a few rapids downstream of the ...

Performance of tambacu hybrid (♂Piaractus mesopotamicus x ♀Colossoma macropomum) and its parental pacu (Piaractus mesopotamicus) evaluated in cages under different feeding programmes

open access: yesAquaculture Reports, 2020
We evaluated the growth and body traits of pacu and tambacu hybrid reared in cages and fed through different feeding programmes. Six treatments in a factorial scheme, with two genetic groups (pacu and tambacu) and three feeding programmes, were tested in

Small fish, large variation: Morphological diversity of Weberian apparatus in Noturus catfishes and ecological implications. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract The Weberian apparatus is a hearing specialization unique to the otophysan fishes, and an unexpected degree of morphological variation exists in species of the Noturus catfishes. Our aim in this study is to investigate relationships between morphological variations and ecology that may drive this variation.

Mega-Bites: Extreme jaw forces of living and extinct piranhas (Serrasalmidae) [PDF]

open access: yesScientific Reports, 2012
Here, we document in-vivo bite forces recorded from wild piranhas. Integrating this empirical data with allometry, bite simulations, and FEA, we have reconstructed the bite capabilities and potential feeding ecology of the extinct giant Miocene piranha, Megapiranha paranensis. An anterior bite force of 320 N from the black piranha, Serrasalmus rhombeus,

Hearing capacities and morphology of the auditory system in Serrasalmidae (Teleostei: Otophysi) [PDF]

open access: yesScientific Reports, 2018
AbstractLike all otophysan fishes, serrasalmids (piranhas and relatives) possess a Weberian apparatus that improves their hearing capacities. We compared the hearing abilities among eight species of serrasalmids having different life-history traits: herbivorous vs. carnivorous and vocal vs. mute species.
