Summary
Poecilia reticulata is a small benthopelagic fish native to Brazil, Guyana, Venezuela and the Caribbean Islands. It is a popular aquarium species and is also commonly used in genetics research. In the past Poecilia reticulata was widely introduced for mosquito control but there have been rare to non-existing measurable effects on mosquito populations. It can occupy a wide range of aquatic habitats and is a threat to native cyprinids and killifishes. It is a carrier of exotic parasites and is believed to play a role in the decline of several threatened and endangered species.
Species Description
Poecilia reticulata is a very small opportunistic benthopelagic (feeding on bottom, midwaters, or near the surface) non-migratory fish that can inhabit both fresh and brackish water.P. reticulata males are smaller, reaching an average length of 3.5cm compared 5cm in females. Besides being half the size of females, males have a colourful tail and caudal fin. This species has 7-8 dorsal soft rays and 8-10 anal soft rays (FishBase, 2006).
Uses
Poecilia reticulata is a popular aquarium species and is also commonly used in genetics research. In the past P. reticulata was widely introduced in hopes of gaining mosquito control, but there have been rare to non-existing measurable effects on mosquitoes populations (FishBase, 2006).
Habitat Description
Occurs in warm springs and their effluents, weedy ditches and canals. Found in various habitats, ranging from highly turbid water in ponds, canals and ditches at low elevations to pristine mountain streams at high elevations. Has a wide salinity range but requires fairly warm temperatures (23-24 °C) and quiet vegetated water for survival (FishBase, 2006).
Reproduction
Male Poecilia reticulata anal fins are transformed into a gonopodium for internal fertilization. Males are continuously chasing and mating females. Females can store sperms for later fertilization and may produce young every four weeks. Pregnant females are recognizable by black triangle between anal and pelvic fins. After a gestation period of four to six weeks females give birth to 20-40 live young. No parental care is exercised and parents may even prey on their young (FishBase, 2006).
Nutrition
Feeds on zooplankton, small insects and detritus. Feeds mainly on insects and has been observed consuming: ceratopogonids, chironomids, culicids, dipterans, hemipterans, and hymenopterans (FishBase, 2006).
Pathway
P. reticulata is a popular aquarium species (FishBase, 2006). Guppies are also popular ornamental fish in Australia, and introductions may have resulted from escapes or releases from aquaria or outdoor breeding ponds (Linholm et al., 2005 i

General Impacts
Poecilia reticulata is considered a hazard to native cyprinids and killifishes in the United States. It has been implicated in the decline of native fishes in Nevada and Wyoming, and of native damselflies in Hawaii. It is a known carrier of trematode parasites, which may affect native fish populations (Nico, 2001). It eats the eggs of native fish species and acts as a host for the parasitic nematode Camallanus cotti, and the Asian tapeworm Bothriocephalus acheilognathi in Hawaii (Eldredge, 2000).

Hybrids between P. reticulata and P. mexicana and between P. reticulata and Xiphophorus helleri are shown to threaten species of native fish in the western USA (Courtenay and Meffe, 1989 in Eldredge, 2000).

Summary: In 1993, Canada, Mexico and the United States signed the North American Agreement on Environmental Cooperation (NAAEC) as a side agreement to the North American Free Trade Agreement (NAFTA). The NAAEC established the Commission for Environmental Cooperation (CEC) to help the Parties ensure that improved economic efficiency occurred simultaneously with trinational environmental cooperation. The NAAEC highlighted biodiversity as a key area for trinational cooperation. In 2001, the CEC adopted a resolution (Council Resolution 01-03), which created the Biodiversity Conservation Working Group (BCWG), a working group of high-level policy makers from Canada, Mexico and the United States. In 2003, the BCWG produced the �Strategic Plan for North American Cooperation in the Conservation of Biodiversity.� This strategy identified responding to threats, such as invasive species, as a priority action area. In 2004, the BCWG, recognizing the importance of prevention in addressing invasive species, agreed to work together to develop the draft CEC Risk Assessment Guidelines for Aquatic Alien Invasive Species (hereafter referred to as the Guidelines). These Guidelines will serve as a tool to North American resource managers who are evaluating whether or not to introduce a non-native species into a new ecosystem. Through this collaborative process, the BCWG has begun to implement its strategy as well as address an important trade and environment issue. With increased trade comes an increase in the potential for economic growth as well as biological invasion, by working to minimize the potential adverse impacts from trade, the CEC Parties are working to maximize the gains from trade while minimizing the environmental costs.
