Nematode parasites of the characid fish Brycon hilarii from the River Juba, Mato Grosso, Brazil [PDF]

Helminthologia, 2006
Abstract Specimens of the characid fish Brycon hilarii collected in dry and wet seasons in the River Juba, Tangará da Serra, State of Mato Grosso, Brazil, were surveyed for nematode parasites. Contracaecum sp. Type 1 and Type 2 larvae of Moravec, Kohn et Fernandes, 1993 were detected in the mesentery and liver, and Neocucullanus ...

Heterochromatin patterns and karyotype relationships within and between the genera Brycon and Salminus (Pisces, Characidae)

Genetics and Molecular Biology, 1999
Chromosomes of two Brycon species (B. lundii and B. microlepis) and Salminus hilarii were analyzed. Based on constitutive heterochromatin distribution patterns, karyotypic relationships within and between Bryconinae and Salmininae were examined.

Population genetic structure revealed by a school of the freshwater migratory fish, Brycon hilarii

Latin American Journal of Aquatic Research, 2012
It is believed that different genetic populations of migratory fishes can co-exist in a single hydrographic system. Although different populations may occupy and explore the river together, they segregate during the spawning season and consequently the population genetic structuring is maintained.

Ocimum gratissimum essential oil in the transport water of Brycon hilarii: implications at water quality, blood parameters and residues in tissue and plasma [PDF]

Brazilian Journal of Biology
Transporting live fish is a common practice in fish farming, and is certainly one of the main problems that affect fish homeostasis. In this scenario, the use of natural additives has shown promise in improving fish resistance to adverse situations. This

Ichthyofauna used in traditional medicine in Brazil. [PDF]

Evid Based Complement Alternat Med, 2012
Fish represent the group of vertebrates with the largest number of species and the largest geographic distribution; they are also used in different ways by modern civilizations. The goal of this study was to compile the current knowledge on the use of ichthyofauna in zootherapeutic practices in Brazil, including ecological and conservational commentary

Dynamics of fish larvae recruitment in the hydrographic basin of the Paraguay River in western Brazil [PDF]

Neotropical Ichthyology, 2023
The conservation of fish assemblages depends on the longitudinal and lateral connectivity between riverine habitats, in particular during the breeding season and the initial development.
