triploid

triploid
an abnormal chromosome complement, three times the number in gametes. The usual complement in a species is twice that in gametes, e.g. artificially induced in Ctenopharyhgodon idella for stocking purposes so that escapees cannot reproduce. The process of turning fish into triploid involves either heat, cold, pressure or chemical shocks during the period just after fertilisation. The process only works on female fish; the male fish are only partially affected
