“…Thus, propagation of this ‘primary farmed type’ (Mair & Lucente 188 ) has been established to produce fingerlings for local tambaqui farming. The genetic diversity of captive populations maintained in public and private hatcheries was assessed using multiple molecular markers, including random amplified polymorphic DNA (RAPD), 192,205,206 mitochondrial DNA, 207‐209 inter‐simple sequence repeat (ISSR), 210 microsatellite 208,211‐215 and SNP 216 markers. Altogether, it was shown that the genetic resources of farmed tambaqui broodstock in the Amazon region and across other South American regions underwent loss of genetic diversity, which can be attributed to the lack of effective breeding management and founder effects resulting from the species’ high fecundity and small number of broodstock utilized.…”
