The county name (Piracicaba, where Oxipira is based) comes from the Tupi language and means "the place where the fish comes" through the junction of the terms 'pirá' ("fish"), 'syk' ("get") and 'aba' ("place"). It is a reference to the Piracicaba River Falls, which block the migration (spawning) fish.
Attached have some further explanation about the concept. (I really hope the client like it!) :)
