Bioconcentration of trichlorfon insecticide in pacu (Piaractus mesopotamicus)
Chemosphere, 2006Pacu (Piaractus mesopotamicus) is one of the most representative fish species of Brazilian fish culture, produced in most Brazilian States due to its importance for food diet and sport fishery. This research work investigated the bioconcentration of trichlorfon [phosphonic acid, (2,2,2-trichloro-1-hydroxyethyl)-dimethyl ester] insecticide in pacu under

Temperature and hypoxia on oxidative stress responses in pacu Piaractus mesopotamicus
Journal of Thermal Biology, 2020The aim of this study was to verify the effects of the interaction between different temperatures and levels of dissolved oxygen in the oxidative stress parameters of pacu juveniles. A total of 81 pacu juveniles (61.7 ± 9.1 g) were exposed to three temperatures (18, 23, and 28 °C), acclimated for a period of 30 days, and then submitted to three levels ...

Low Temperature Tolerance of Pacu, Piaractus mesopotamicus
Environmental Biology of Fishes, 2000Pacu, Piaractus mesopotamicus (=Colossoma mitrei), is a South American warm water fish species found in the temperature range of 15–35°C. The culture of a warm water species in temperate regions demands knowledge on its temperature requirements. Pacu introduction into the Israeli fish culture system is being considered.

Effects of cold stress on juvenile Piaractus mesopotamicus and the mitigation by β-carotene
Journal of Thermal Biology, 2020This study investigated the effects of cold stress on morphometrical and hematological biomarkers, energy metabolism, and oxidative stress in different tissues of P. mesopotamicus, and the protective role of β-carotene. Fish were fed with a control diet (CD) and the same diet supplemented with 105 mg/kg β-carotene (BD) for 60 days.

Effectiveness of therapeutic agents in disease treatment in Piaractus mesopotamicus
Aquaculture, 2014The use of drugs in aquaculture is necessary to combat pathogens responsible for causing the high rate of mortality in fish farming, such as infection by ectoparasites. The aim of this research was to evaluate the efficacy: (A) of toltrazuril (TOL) treatment against Ichthyophthirius multifiliis, Trichodina heterodentata and Anacanthorus penilabiatus ...

Complete mitochondrial genome sequence of Piaractus mesopotamicus (Holmberg, 1887)
Mitochondrial DNA Part A, 2014The migratory species Piaractus Mesopotamicus, popularly known as the pacu, was determined to have a complete mitochondrial genome of 16,722 bp with 45% GC content. The genome contained 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, and a 1048 bp Control Region (D-loop).

Veterinary Parasitology
Biosecurity in aquaculture is essential to reduce disease burden and ensure sustainability. Piaractus mesopotamicus (pacu) is a key species in South American aquaculture, yet parasitic threats to its health remain understudied. We analyzed intestinal helminth and assessed their effects on the health of 34 farmed pacu reared in intensive and semi ...

Environmental Science and Pollution Research
Microplastics, considered emerging environmental contaminants resulting from plastic degradation, are discovered in diverse aquatic ecosystems and can be unintentionally ingested by fish. Therefore, it is essential to characterize their interaction with other contaminants, such as agrochemicals, in aquatic environments.
