who is the carachi-de-tschudi
Tschudi's carachi is a small freshwater killifish of the family Cyprinodontidae, reaching 20 cm. It lives in Lake Titicaca and its basin, in Peru and Bolivia, at high altitude. It stays near the bottom and also in the midwater, without migrating. The species is considered vulnerable, has commercial fishing, and is sold for aquariums, where it is hard to keep. It is not a target of recreational angling, and it is best to avoid catching it where it still occurs.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the carachi-de-tschudi; in the meantime, see the similar species.
identification
Titicaca carachi, without pelvic fins, like the other members of the genus Orestias. It shares the lake with Agassiz's carachi, the yellow carachi and Cuvier's carachi, and size tells them apart: at up to 20 cm, it is larger than Agassiz's (15 cm) and the yellow (17 cm), and smaller than Cuvier's (27 cm).
