         一般影響

    在美國,孔雀花鱂(Poecilia reticulata)被認為會威脅到本地鯉科魚類和鱂魚。它造成了內華達州和懷俄明州的原生魚類,和夏威夷的原生豆娘魚族群下降。它是寄生吸蟲的載體,可能會影響本地魚類族群(Nico, 2001)。在夏威夷,它吃原生魚類的卵,也是寄生線蟲和亞洲絛蟲的宿主(Eldredge, 2000)。
    孔雀花鱂(P. reticulata) 會和 P. mexicana雜交,也會和 Xiphophorus helleri雜交,會威脅美國西部的本土魚類物種(Courtenay and Meffe, 1989 in Eldredge, 2000)。



         地點特有的影響:
    Oahu Is. (United States (USA)) English 
    病原: P. reticulata also presents a threat because it is a known carrier of certain exotic trematode parasites. P. reticulata, among other introduced poeciliids, have been implicated in the decline of native damselflies on Oahu, Hawaii. Often the distributions of the damselflies and introduced fishes were found to be mutually exclusive, probably resulting from predation of the fish on the insects (Nico, 2006).

    Nevada (United States (USA)) English 
    威脅瀕危物種: P. reticulata has adversely affected the White River springfish Crenichthys baileyi in a Nevada spring. Two subspecies of this springfish are now listed as federally endangered, and three others are proposed for listing (Nico, 2006).
    Wyoming (United States (USA)) English 
    威脅瀕危物種: P. reticulata has also been implicated in the decline of the Utah sucker Catostomus ardens in a thermal spring in Wyoming. The guppy has become the dominant species in some warm water springs in the west (Nico, 2006).
