Guppies in the US: likely the result of aquarium or fish farm releases

Guppies, also known as millionfish or rainbow fish, are native to northeast South America, specifically the countries of Antigua and Barbuda, Barbados, Brazil, Guyana, Trinidad and Tobago, and Venezuela. They are highly adaptable and can survive in a wide range of environmental and ecological conditions. As a result, they have been introduced to many different countries and are now found all over the world, including the United States.

In the US, the presence of guppies is likely due to their release from aquariums or fish farms. Guppies are extremely popular for home aquariums due to their small size, colourful appearance, and ease of care. They are also used in genetic research because of their large populations.

Guppies have been found in many US states, including Hawaii, Idaho, New Mexico, Nevada, Texas, and Wyoming, where they are considered established species. They have been implicated in the decline of native fish subspecies and insects, such as the White River springfish in Nevada and damselflies in Oahu, Hawai'i.

Guppies are considered invasive in the US due to their ability to adapt and thrive in new environments. They can tolerate a wide range of water temperatures, salinity levels, and pH levels. Additionally, they are carriers of various parasites and diseases that can further damage local populations.

Guppies in Hawaii, Idaho, New Mexico, Nevada, Texas, and Wyoming

Guppies (Poecilia reticulata) are a species of small tropical freshwater fish that are popular in home aquariums. They are native to South America and are an invasive species on nearly every other continent. In the US, guppies have been found in many states, most likely due to their release from aquariums or fish farms. Guppies are now established in Hawaii, Idaho, New Mexico, Nevada, Texas, and Wyoming.

Guppies were first observed and considered established in Hawaii in 1922, likely introduced through fish farms or the release of aquarium fish. They are implicated in the decline of native damselflies in Oʻahu, probably due to predation. Guppies eat the eggs of native fish, resulting in population decline, and act as hosts for certain parasites.

In Idaho, guppies have likely been introduced through similar means as in Hawaii. While their specific impact on the state's ecology is unclear, their presence in other states has led to the decline of native fish populations.

Guppies have also become established in New Mexico, likely due to releases from aquariums or fish farms. As an invasive species, they can cause significant harm to local ecologies by preying on native insects and the eggs of native fish species.

Nevada is another state where guppies have been implicated in the decline of native fish populations, specifically the White River springfish. As an invasive species, they can outcompete and prey on native species, leading to population declines.

In Texas, guppies have likely been introduced through aquarium or fish farm releases. While their specific impact on the state's ecology is unknown, their presence as an invasive species can lead to the decline of native fish populations, as seen in other states.

Wyoming is another state where guppies are now established, and they have been implicated in the decline of the Utah Sucker fish. As an invasive species, guppies can carry diseases and parasites that can further damage local populations.

Guppies as an invasive species: their impact on native fish populations

Guppies (Poecilia reticulata) are a highly invasive species, having been introduced to every continent except Antarctica. In the US, guppies have been found in many states, most likely due to their release from home aquariums or fish farms. They are considered established in Hawaii, Idaho, New Mexico, Nevada, Texas, and Wyoming, and have been implicated in the decline of native fish populations in these states. Guppies are also considered invasive in Guam, Puerto Rico, and the Virgin Islands.

Guppies are native to certain countries and islands in South America, including Antigua and Barbuda, Barbados, Brazil, Guyana, Suriname, Trinidad and Tobago, and Venezuela. They are highly adaptable and can live in a wide range of habitats, from freshwater streams to brackish water environments. This adaptability, combined with their popularity in the aquarium trade, has contributed to their spread as an invasive species.

The impact of guppies on native fish populations is significant. Guppies are known to eat the eggs and larvae of native fish species, leading to population declines. They are also carriers of various parasites and diseases that can harm local fish populations. In Hawaii, guppies have been implicated in the decline of native damselflies in Oʻahu.

The introduction of guppies to new habitats poses a major threat to native fish populations. Their ability to adapt to a wide range of environmental conditions, their high reproductive rate, and their tolerance for a wide range of water temperatures and salinities all contribute to their success as an invasive species.

In some cases, guppies were intentionally released into water bodies to control mosquito populations. However, they have often had a negative impact on native fish populations instead of the intended effect. The introduction of guppies can disrupt the natural balance of an ecosystem, leading to a decline in biodiversity and the loss of genetically distinct populations.

The invasive success of guppies can be attributed to a combination of behavioural and biological factors. Guppies exhibit shoaling behaviour, which provides protection against predation. This behaviour also facilitates contact and mating between invading and native individuals, leading to population mixing and genetic homogenisation. Male guppies do not discriminate between native and non-native females, further promoting population mixing.

The impact of guppies as an invasive species is a growing concern, and understanding their ecological and behavioural adaptations is crucial for effective management and control.
