This species is known from Lake Pátzcuaro, Lake Cuitzeo and the surrounding streams in Río de Morelia, central Michoacán, Mexico.
Habitat and Ecology
It is an aquatic species that lives in deep water with abundant nutrients; eggs are laid in the streams.
It used to be common but over harvesting has greatly reduced the population.
This species is locally exploited for human consumption, particularly around the Lake Pátzcuaro area where it is considered a delicious dish. However, no data are available regarding the number of individuals in the local trade.
It is not known from any protected areas. The effect of the local trade on the population status of the species in the Lake Pátzcuaro area needs to be evaluated, and there is a need to manage the offtake of this species for human consumption in a sustainable manner. This species is protected by Mexican law under the "Special Protection" category (Pr).
Red List Status
Listed as Endangered because of an observed population decline, estimated to be more than 50% over the last ten years, due to over-harvesting and other threats; and because its Extent of Occurrence is less than 5,000km2, its Area of Occupancy is less than 500km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its habitat, and in the number of mature individuals, in central Michoacán, Mexico.
This species is a member of the Lithobates pipiens complex.
