Data of de novo assembly from liver transcriptome of pirapitinga Piaractus brachypomus. Samples for transcriptome sequencing To perform the transcriptome sequencing, samples of liver tissue were taken from 10 individual fish from three different Brazilian fish farms and one wild population: Chattarje and Mazumdar, ; Dabrowski, et al. Estimating F-statistics for the analysis of population structure. Table 3 Values of genetic diversity of eight microsatellite loci of Piaractus brachypomus.

Piaractus brachypomus – Wikipedia

No sequence showed homology with known pirapitinga protein sequences deposited in NCBI database, because the available sequences database is still limited to mostly mitochondrial sequences. Eggs generally hatch between 12 and 20 hours after fertilization.

ADW doesn’t cover all species in the world, nor does it include all the latest scientific information about organisms we describe. A high-resolution map of the Nile tilapia genome: In the aquarium offer it a varied diet consisting of quality dried pellets or floating sticks, along with plenty of fruit and vegetables.

brachypomjs The inbreeding coefficient F IS was performed using Genepop 4. A study of the contents of pacu stomachs recorded seeds from 27 tree and 26 non-woody plant species. North fish farms; 3: Primers flanking the microsatellite loci were designed with Primer3plus software Rozen and Skaletsky, The use, distribution or reproduction in other forums is permitted, provided the piarcatus author s and the copyright owner are credited and that the original publication in this journal is cited, in accordance with accepted academic practice.

In relation to the protein Piaracts of zebrafish and fuguwe found similar numbers of annotated genes, which were of 2, In the present study, genes assigned to the immune system, growth and reproduction were found, and therefore these data will serve as support for future studies on the aquaculture of pirapitinga.

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

Although males produce sperm year-round, one study found that females were sensitive to seasonal cycles and sometimes would piarcatus ovulate even after artificial induction.

However, these markers are not available for pirapitinga, one of most important species for the aquaculture in South America.

The ADW Team gratefully acknowledges their support. Due to their large size and food requirements, it may easy for pacu to outcompete native species. Mastrochirico-Filho1 Milene E.

Information regarding the home range size of this and other pacu species is currently lacking. Microsatellites were identified in the contigs using msatcommander software Faircloth, Its natural diet of fruit and nuts is said to enhance the flavour of the flesh. Evolution 43— The pirapitinga is often kept in aquaculture.

Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. It tends to prefer shallow, slow-moving areas with overhanging or floating vegetation. After LD analysis, level of admixture among population samples was inferred by estimating the optimum number of clusters Kas suggested by Evanno et al.
