For this, the sagittae otoliths of the species Cichla temensis, C. orinocensis and C. monoculus were sampled, collected in three rivers (Negro river, Uatum?? river and Jatap?? river) belonging to the Amazon basin. Using linear measurements, relationships were established between the body and the otolith of the species Cichla temensis. The linear regression models for the weight and length of the otoliths in relation to the same body dimensions of the fish showed strong correlations, mainly for the variable weight with an r2 = 0.92, while the length had an r2 = 0.77. Thus indicating that the dimensions of the otoliths can be used to estimate the size of the individuals of the species studied, and can also be adapted for other fish species. When assessing the shape of the sagittae otoliths to discriminate Cichla species and populations, differences were found between both groups. Among the group of species, the shape of the C. temensis sagitta otolith proved to be completely different from the species C. monoculus and C. orinocensis. While in the group of C. temensis populations, individuals from the Negro and Jatap?? rivers are different regardless of the methods used to describe the shape of the otoliths. The differences found in the shape of the otolith in the group of species can be directly related to genetic factors, while the morphology of the otoliths of the populations can be influenced by environmental variations. These results confirm the ability to differentiate species and populations through the morphology of the otoliths, however, further studies are needed to verify the role of the genetic effect in comparison to the environmental and biotic effects to clarify the differences observed in the otoliths. Com a finalidade de aumentar o arcabou??o de t??cnicas que possibilitam o avan??o sobre o conhecimento dos par??metros populacionais das esp??cies de peixes, o presente estudo utilizou duas abordagens morfom??tricas empregando t??cnicas tradicionais (medidas lineares) e geom??tricas (forma), sobre as esp??cies do g??nero Cichla, com o objetivo de estabelecer rela????es morfom??tricas entre o corpo e o ot??lito, e distinguir esp??cies e popula????es atrav??s da forma do ot??lito sagitta. Para isso, foram amostrados os ot??litos sagittae das esp??cies Cichla temensis, C. orinocensis e C. monoculus, coletadas em tr??s rios (rio Negro, rio Uatum?? e rio Jatap??) pertencentes ?? bacia Amaz??nica. A partir do uso das medidas lineares foram estabelecidas rela????es entre o corpo e o ot??lito da esp??cie Cichla temensis. Os modelos de regress??o linear para o peso e o comprimento dos ot??litos em rela????o as mesmas dimens??es corporais do peixe mostraram fortes correla????es, principalmente para a vari??vel peso com um r2 = 0,92, enquanto o comprimento teve um r2 = 0,77. Indicando assim que as dimens??es dos ot??litos podem ser usadas para estimar o tamanho dos indiv??duos da esp??cie estudada, podendo ser adaptadas tamb??m para outras esp??cies de peixe. Quando avaliado a forma dos ot??litos sagittae para discriminar esp??cies e popula????es de Cichla, foram verificadas diferen??as entre ambos os grupos. Dentre o grupo das esp??cies, a forma do ot??lito sagitta do C. temensis mostrou ser completamente diferente das esp??cies C. monoculus e C. orinocensis. Enquanto no grupo das popula????es de C. temensis, os indiv??duos dos rios Negro e Jatap?? mostram-se diferentes independe dos m??todos utilizados para descrever a forma dos ot??litos. As diferen??as encontradas na forma do ot??lito no grupo das esp??cies podem estar relacionadas diretamente com fatores gen??ticos, enquanto que a morfologia dos ot??litos das popula????es podem estar sobre influencias das varia????es ambientais. Esses resultados confirmam a capacidade de diferencia????es de esp??cies e popula????es atrav??s da morfologia dos ot??litos, no entanto, s??o necess??rios mais estudos para verificar o papel do efeito gen??tico em compara????o aos efeitos ambientais e bi??ticos para esclarecer as diferen??as observadas nos ot??litos.
