| loss of genetic diversity in farmed populations of colossoma macropomum estimated by microsatellites. | the genetic variability of four colossoma macropomum broodstocks, three from fish farms in different regions and one from the natural environment in brazil, was analyzed using microsatellite markers. the wild progeny (n = 30) were caught in the solimões-amazonas river, at the varzea lakes; this location is used to mature the fish from larvae to juveniles. the three fish farms were selected according to the age of their lineages and broodstock availability: dnocs (n = 21) is located in the ceará ... | 2016 | 26970241 |
