Conservazione: Crenicichla hu è valutata dalle organizzazioni internazionali di salvaguardia delle specie a rischio come (EN) Pericolo (2020). Crenicichla hu is only known from its type locality in Piray Miní stream, an affluent of Paraná river in Misiones province. This basin has no protection and its ecological status requires urgent protection and restoration. There is an evidence of continuous habitat conversion, especially in the upper reach where this species occurs. The type locality represents a single threat based location (from Liotta, 2022).
