Abstract
Atlantic salmon precocious parr are dwarf mature males able to mate with adult females making profit of their small size. In this work the reproductive success of the dwarf males in the presence of an adult male and female spawning couple has been estimated in three different situations under simulated natural conditions at the Lapitxuri experimental channel (France). Different hypervariable minisatellite loci were used in the paternity assessment of the progeny. In all the situations tested, precocious parr were able to fertilize between 24.7 and 89.3 per cent of the total eggs. The results are discussed in relation to the important role of Atlantic salmon precocious parr in population structure and the evolution of salmon populations.
