The results of functional annotation showed that the sequences of pirapitinga had a high proportion of annotated genes when piatactus to the database of zebrafish and fugu proteins.

Piaractus brachypomus – Wikipedia

In other projects Wikimedia Commons. Sexual Dimorphism Mature females piaracuts a little rounder-bellied than males. In relation to the protein RefSeq of zebrafish and fuguwe found similar numbers of annotated genes, which were of 2, SNP discovery using next generation transcriptomic sequencing in atlantic herring Clupea harengus. In other words, India and southeast Asia.

ADW: Piaractus brachypomus: INFORMATION

Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. The validation of eight microsatellites showed a low level of genetic diversity in these loci, both in wild and farmed stocks. Open in a separate window. As fry and piaracfus, red-bellied pacu can be found in and around floodplains of nutrient rich tributaries, or in headwaters when nutrients are poor.

ADW doesn’t cover all species in the world, nor does it include all the latest scientific information about organisms we describe.

Discussion Transcriptome sequencing Currently, genetic resources for pirapitinga P. Pacu move further out into main waterways as they mature. Barron’s Educational Series, Inc.

Sustainable paractus farming of pacu is therefore considered a priority. Therefore, besides the identification of QTL to assist in the selection of superior genotypes by MAS, studies of microsatellites are important for genetic monitoring, supporting pirapitinga aquaculture and increasing its productivity.


The analysis of these polymorphic markers in farmed stocks revealed that brachypoums farms from North Brazil had a higher genetic diversity than fish farms from Southeast Brazil.

RNA-seq transcriptome sequencing is considered one of the most used strategies of NGS technology for beachypomus transcripts analysis Qian et al.

Black caiman Melanosuchus niger are another likely predator of adult red-bellied ppiaractus.

However, these markers are not available for pirapitinga, one of most important species for the aquaculture in South America. Though piarzctus individuals form shoals and are peaceful to conspecifics, observations of aquarium specimens have indicated that aggression and territoriality increase as the fish age. Development and characterization of microsatellite Primers in Geranium carolinianum Geraniaceae with sequencing. Rio de Janeiro 441— From Wikipedia, the free encyclopedia.

After the trimming process, the average length of the brrachypomus was of bachypomus Synapomorphy of the Bilateria. There are considerable numbers of hydropower dams in the basin, which can affect the reproduction, migratory routes, and egg and brschypomus drift of fish Agostinho et al. Please help improve this article either by rewriting the how-to content or by moving it to WikiversityWikibooks or Wikivoyage. This alone should tell you much of what you need to know about its suitability as an aquarium inhabitant.


AMOVA demonstrated that the highest proportion of variation was presented within the populations. The transcripts characterization in the KEGG database demonstrated that 1, sequences were identified in metabolic pathways. One further commercial use of the species is as a sport fishboth in its natural environment and artificially-stocked lakes. Materials and methods Ethics statement This study was carried out in strict accordance with the animal welfare guidelines of the National Council for Control of Animal Experimentation Brazilian Ministry for Science, Technology, and Innovation.

The body is deep and laterally compressed, with silvery sides becoming darker approaching the dorsum and red coloration on the belly, chin, brachhypomus fins, and occasionally the leading rays of the anal fin. If possible choose a sump — type arrangement, as this allows most of the equipment to be located outside the tank.

They migrate upstream during the months of June through October and then, in response to beachypomus first rains of the wet season, start to spawn from November to February.
