Phylogenomics of the Neotropical fish family Serrasalmidae with a novel intrafamilial classification (Teleostei: Characiformes)

Molecular Phylogenetics and Evolution, 2020
The Neotropical fish family Serrasalmidae comprises 16 extant genera and 101 species widespread through major Neotropical rivers with relevant importance for regional fisheries and aquaculture. The monophyly of Serrasalmidae and the recognition of three main clades are recurrent between morphological and molecular phylogenies.

Tooth structure, mechanical properties, and diet specialization of Piranha and Pacu (Serrasalmidae): A comparative study

Acta Biomaterialia, 2021
The relationship between diet, bite performance, and tooth structure is a topic of common interest for ecologists, biologists, materials scientists, and engineers. The highly specialized group of biters found in Serrasalmidae offers a unique opportunity to explore their functional diversity.

The complete mitochondrial genome sequence of Colossoma macropomum (Characiformes: Serrasalmidae)

Mitochondrial DNA Part A, 2015
Colossoma macropomum (Cuvier, 1816) is the largest characin of South America. This species and its congeners mainly feed on zooplankton, insects, snails and decaying plants. In this paper, we sequenced and annotated the complete mitogenome of C. macropomum. The total length is 16,703 bp, and it typically consist of 37 genes, including 13 protein-coding

Antioxidant processes of the wild tambaqui, Colossoma macropomum (Osteichthyes, Serrasalmidae) from the Amazon

Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1999
Colossoma macropomum, locally called tambaqui, is a freshwater migratory teleost that shows good tolerance to oxygen and pH changes in water, and both chemical-physical parameters change markedly during the day time and seasonal water level oscillations in the Amazon Basin.

Microstructural and compositional variation in pacu and piranha teeth related to diet specialization (Teleostei: Serrasalmidae)

Journal of Structural Biology, 2020
In any vertebrate group, tooth shape is known to fit with a biological function related to diet. However, little is known about the relationships between diet and tooth microstructure and composition in teleost fishes. In this work, we describe the external morphology, internal microstructure and elemental composition of the oral teeth of three ...

Communities of parasite metazoans in Piaractus brachypomus (Pisces, Serrasalmidae) in the lower Amazon River (Brazil) [PDF]

Brazilian Journal of Veterinary Parasitology, 2016
Abstract The aim of this study was to investigate the component community of parasite metazoans of Piaractus brachypomus in the lower Amazon River, northern Brazil. From 34 necropsied fish, 27,384 metazoan parasites were collected, such as Anacanthorus spathulatus, Mymarothecium viatorum and Notozothecium janauachensis (Monogenoidea); Spectatus ...

How was a Pirapitinga, Piaractus brachypomus (Serrasalmidae) introduced in Croatian freshwaters?

2011
In the last week of July 2010, were caught accidentally two adult individuals of pirapitinga Piaractus brachypomus (Cuvier, 1818) in the Croatian waters. The first individual was caught in the main river channel of the Drava River (45°37’24”N; 18°33’15”E), 12 km upstream of the City of Osijek. The second individual was caught in the main channel of the

Toxicological, hematological and immunological effects of levamisole and ivermectin diet supplementation on Colossoma macropomum (Serrasalmidae)

Diseases of Aquatic Organisms, 2019
This study investigated the toxicological, hematological and immunological effects of diets supplemented with levamisole and ivermectin on Colossoma macropomum. Fish were fed for 24, 96 and 240 h with diets containing 300, 600, 900 and 1200 mg of levamisole kg-1 of feed.

Physiological adaptation to hypoxia of a neotropical characoid fish Colossoma macropomum, Serrasalmidae

Environmental Biology of Fishes, 1984
Investigations of seasonal changes in the hematological parameters of Colossoma macropomum revealed that during times of the year when they are exposed to low oxygen concentrations (< 0.5 mg 1−1), there is an increase in the hemoglobin content of the blood and the erythrocyte count.

Aspects of acoustic communication in Serrasalmidae

2018
In Teleostei, the evolution of the ability to produce sounds has provided a great diversity of sonic mechanisms, even at the intrafamilial level. However, the constraints modulating the evolution of sound-producing mechanisms and hearing structures are very little supported by comparative anatomy studies and it is not determined in fish if the ...
