Reproduction impairment following paternal genotoxin exposure in brown trout (Salmo trutta) and Arctic charr (Salvelinus alpinus)
International audience This work describes some consequences of paternal germ cell DNA damage on the reproduction success in two fish species. Male brown trout (n = 31) and male Arctic charr (n = 28) were exposed to the model genotoxicant MMS at the end of spermatogenesis to generate a significant D...
