These fish are routinely stocked by the District to control mosquito populations in sources such as artificial lakes, irrigation ditches, and industrial ponds.
It is against California Department of Fish and Game regulations for private citizens to plant mosquitofish in waters of the state without a permit.
To avoid competition with sensitive native amphibians and fish species, we do not stock mosquitofish in habitats where such species are known to be present.
