important part of the diet of the frog, but not recorded in a recent study of its diet. Although not yet detected in T. macrostomus, some of its relatives have strongly declined due to diseases like chytridiomycosis and Ranavirus. Mass deaths have occurred in T. macrostomus, with a particular large one in 1996, but the reason for this is unknown. Much of its range is within reserves, but protection is insufficient. Local and national groups, partially funded internationally, have started monitoring and conservation projects for this species, and education for the people living in its range. In 2008, an experimental captive breeding program was initiated at two centers at Lake Junin and it resulted in a few thousand tadpoles, but this project ceased in 2012. Following progress and success with the captive breeding program for the related Titicaca water frog, it is planned to expand it to the Junin species at Huachipa Zoo in Lima.
