Aquaculture69— These values confirm the low genetic variability when compared with related species, such as pacu P. In general, lack of knowledge on genetic variability of stocks can result in inbreeding and fixation of deleterious genes, reduced growth rates, disease resistance problems and reduced ability to adapt to new environments Arkush et al.


This relationship has been negatively impacted by climate change, ranching, irresponsible farming practices and logging. Habitat associations of exploited fish species in lower Amazon-floodplain system. It can take a lot of time for them to get accustomed to the aquarium, and may try to jump out frequently.

Pacu have developed amazing dentition to allow them to crush fruit, nuts and seeds. Starvation alters the liver transcriptome of the innate immune response in Atlantic salmon Salmo salar.

Of the 2, contigs with correspondence in the nr database, 2, As pacu get older brachupomus surpass the size of an average piranha, the spots disappear. By the time that they hatch, pacu fry have a fully developed nervous system with a heightened number of neurons in the fore- and hindbrain. The overall size to which it can grow remains a matter of considerable debate and no small amount of confusion. Information regarding the home range size brachypomsu this and other pacu species is currently lacking.

Froese and Pauly, ; Innes, Mating System polygynandrous promiscuous Breeding occurs in annual cycles with the onset of the wet season. For microsatellite validation and genetic variability analysis, fin fragments were collected from each fish under benzocaine anesthesia and all efforts were made to minimize suffering.


The objectives of this study were: However, these genetic patterns should be also evaluated using neutral markers microsatellites in noncoding regions and through techniques of higher genome coverage SNP, single-nucleotide polymorphism. Microsatellite validation was performed in 30 loci, selected according to the motif and functional annotation of the contigs.
