Parasitic infections of Piaractus mesopotamicus and hybrid (P. mesopotamicus xPiaractus brachypomus) cultured in Brazil [PDF]
This study evaluated the occurrence of parasitic infections in the “pacu” fish Piaractus mesopotamicus and the “patinga” hybrid (P. mesopotamicus x Piaractus brachypomus) in the northwest of São Paulo State, Brazil. Fish from the following three fish farms were evaluated every two months: A, a hatchery and larviculture farm (n = 16 pacu / n = 19 ...

Molecular Characterization of Neurogranin (NRGN) Gene from Red‑Bellied Pacu (Piaractus brachypomus). [PDF]
AbstractNeurogranin (NRGN) is a small brain protein expressed in various telencephalic areas and plays an essential role in synaptic plasticity by regulating the availability of calmodulin (CaM). The study aims to characterize the neurogranin gene in Colombian native fish, red-bellied pacu, Piaractus brachypomus, its basal tissue expression and ...

Air exposure test in Colossoma macropomum juveniles maintained in water at suboptimal temperature: Physiological, metabolic and oxidative stress responses. [PDF]
Abstract This study evaluated the physiological, metabolic and oxidative responses of Colossoma macropomum subjected to air exposure when maintained in water at suboptimal temperature (23°C). A total of 54 fish (81.33 ± 11.90 g) were distributed into nine tanks (6 fish per tank). For the air exposure test, 24 animals were exposed for 30 min and another

Contribution of Amino Acids in Cereal Grain Products to Precision Feed Formulation for Tambaqui (Colossoma macropomum) Using a Digestibility Approach. [PDF]
ABSTRACT Although cereal grain products have low protein content, they can contribute up to 25% of total protein in low‐trophic level/omnivorous fish diets. Thus, understanding the amino acid contribution of these ingredients becomes crucial for meeting the dietary requirements of omnivorous fish.

Weight-Length Ratio of Piranhas <i>Serrasalmus</i> (Characiformes, Serrasalmidae) in Bolivia: Relationships to Molecular Divergence and Maximum Size? [PDF]
This study presents WLRs of nine piranha or palometa fish species of genus Serrasalmus present in the Amazon and La Plata basins of Bolivia and compares differences with genetic divergence (mtDNA COI locus) and the observed maximum size. All species showed an exponential (power type) growth pattern, and all WLRs were significantly different among all ...

The objective of the work was to formulate, characterize and evaluate the stability of a product based on white cachama (Piaractus brachypomus). From four lipid sources (pork back fat, canola oil, olive oil or sacha inchi oil), the one with the highest acceptance rate was selected based on the acceptance index and sensory characteristics.

Cooling of pirapitinga (Piaractus brachypomus) embryos stored at −10ºC
SummaryCryopreservation has not been used successfully to preserve fish embryos, although chilling techniques have been used with good results. The aim of this study was to chill Piaractus brachypomus embryos at – 10°C for various storage times. Embryos at the following ontogenetic stages were used: blastoderm – 1.2 hours post-fertilization (hpf ...
