B or supernumerary chromosomes are extra elements to the A chromosomes complement and can be found in a wide diversity of organisms. These elements are not essential to the life cycle of organisms and are known as parasite chromosomes, once they do not benefit their hosts, but uses their cellular machinery for replication. These chromosomes were described in the fish species Prochilodus l…
Eukaryotic genomas are mainly composed of repetitive DNA sequences. Among them, satellide DNAs (satDNAs) constitute unique tandemly repeated sequences. For a long time, satDNAs were considered as junk DNA; however, the transcription of this kind of sequence in distinct organisms points to different possible established functions. Historically, distinct methods were used to characterize sa…
Fish passages and fish stocking of native species are alternatives to mitigate the impacts that Small Hydroelectric Power plant (SHPs) may have on ichthyofauna. However, scientific knowledge about the real effectiveness of these management tools is lacking. The Sapucaí-Mirim River, an important tributary of Rio Grande (SP/MG), currently dammed by a cascade of three SHPs, has fish ladders …
B or supernumerary chromosomes are characterized as extra chromosomes to the chromosomal pattern of a species, known as A chromosomes, and are found in great diversity, morphological and numerical, in neotropical fish. In the species Prochilodus lineatus, three distinct variants of this supernumerary chromosome are already known, which the studies of its repetitive content, aimed at satel…
The selection of individuals with improved performance for immunological responses contributes for a sustainable Aquaculture. However, the development of genetic basis for breeding programs directed to species of fish from Brazil is still scarce. Infection caused by Aeromonas hydrophila has been responsible for about 20 to 30% of the mortality rates for Pacu (Piaractus mesopotamicus), one…
The study of repeat sequences was greatly impacted by the popularization of Next Generation Sequencing, along with developing new scripts and softwares. With these, bioinformatic collections, such as RepeatExplorer and SatMiner, have been reducing the price and the time of analysis, allowing a higher throughput of the analyzes. Satellite DNA (satDNAs) are repeated tandem sequences and the…
Human interference has contributed to a significant increase in the occurrence of hybrid fish through breeding techniques, commonly used in the marketing of these animals. Among the main objectives of artificial hybridization is the search for a production of animals with better genetic performance, but its production can cause potential genetic risks, as fertile lineages, which may ultim…

The development of genomic tools will be useful to the continuing development of native species production in Brazil, maximizing the genetic gain and, consequently, boosting new selective breeding for these species. The aim objective of this study is to develop genomic tolls directed to identify signatures of resistance in pacu (Piaractus mesopotamicus) to Aeromonas hydrophila based in ch…
The fishes are the most diversified group in the vertebrates with more genetic variation. Nevertheless, aquatic environment has been destroyed due of various factors as riparian degradation, overfishing, pollution and environmental alterations due of multiple use of river system. This modified fragment aquatic ecosystem, interrupting migrations and defining the breeding areas of migratory…
