Paiche (Arapaima gigas) (Cuvier, 1829) (Osteoglossiformes: Arapaimidae): una revisión sistemática de la diversidad genética para la conservación del pez gigante del Amazonas
The paiche (Arapaima gigas) (Cuvier, 1829) (Osteoglossiformes: Arapaimidae) lives mainly in the countries of Peru, Brazil, Ecuador and Guyana. An exhaustive review study was carried out on genetic diversity for the conservation of A. gigas in the Amazon, using as search engines Scielo, academic Google, Google, Researchgate, Scopus, Reabic, PloS One, Springer, PubMed, BMC Genetics and Geneticsmr.com. The following search filter was used: publication date: 2015 to February 2021; type of publications: original articles, scientific notes and books; language: Spanish, English and Portuguese; Search keywords in three languages: “Aparaima gigas”, “paiche”, “genetic conservation of the paiche” and “genetics of conservation”. In the 14 scientific publications compiled, it is observed that genetic variability is affected by the distancing of A. gigas populations in the Amazon basins, and different populations (metapopulations) of A. gigas reproduce with nearby populations, being able to subsequently generate inbreeding. There is greater genetic differentiation between populations of A. gigas at greater distances of separation. A smaller number of studies emphasized the use of genetic biomarkers in A. gigas for population characterization. Recently, molecular genetic techniques and technologies with environmental DNA are being used in species such as the paiche. Insufficient data on this species for population management could lead to a reduction in its genetic diversity or its extinction.
