The guppies were expected to eat the mosquito larvae and help slow the spread of malaria, but in many cases, these guppies have had a negative impact on native fish populations. [10] Field studies reveal that guppies have colonized almost every freshwater body accessible to them in their natural ranges, especially in the streams located near ...
Among aquarium fish, livebearers are nearly all members of the family Poeciliidae and include: guppies, mollies, platies and swordtails. [ 1 ] The advantages of livebearing to the aquarist are that the newborn juvenile fish are larger than newly-hatched fry, have a lower chance of mortality and are easier to care for.
Furthermore, children with the highest counts of blood flukes also had the most malaria attacks. [25] Based on this study, Hartgers et al. drew a "cautious conclusion" that helminths make humans more susceptible to contracting malaria and experiencing some of its lighter symptoms, while actually protecting them from the worst symptoms.

The most commonly kept species are guppies (P. reticulata), mollies (P. sphenops or P. latipinna), and Endler's livebearers . Members of the genus readily hybridize with each other and so most commercially offered fish are hybrids (with guppies having some Endler, and mollies being a mix of common and sailfin mollies). [9]
However, from the 1920s to the 1950s, mosquitofish were considered by some to be a significant factor in eradicating malaria in South America, southern Russia, and Ukraine. Mosquitofish bred by Joice Loch were distributed through Greece, Serbia and the Middle east. [ 29 ]

Parasite load is a measure of the number and virulence of the parasites that a host organism harbours. Quantitative parasitology deals with measures to quantify parasite loads in samples of hosts and to make statistical comparisons of parasitism across host samples.
