Conservazione: Crenicichla yaha non inserita dalle organizzazioni internazionali di salvaguardia delle specie a rischio nella lista rossa. Crenicichla yaha was thought to be lost when a dam was constructed on the Urugua-í stream (Piálek et al., 2015:6) because the snail Potamolithus on which C. yaha feeds is absent from the artificial lake, but it was subsequently rediscovered in December 2016 at two localities outside the influence of the artificial lake. Crenicichla yaha should be considered a rare and vulnerable species (Říčan et al., 2017).
