Abstract

Background. Spotted Raphael catfish, Agamyxis pectinifrons, is native to the Amazon River basin. Its presence in southeastern Mexico was reported for the first time in 2021. Objective. Document the expansion of the spotted catfish in the Grijalva-Usumacinta basin. Methods. Surveys were carried out on finfish and river shrimp fishermen to detect the presence of A. pectinifrons. This was done with the use of photographs in nearby fishing communities, where the first reports were made. Results. The presence of A. pectinifrons was detected in the towns of Tabasquillo and Chichicastle 1st Section, Tabasco, in October and November 2023, respectively. The first reports of this species had been recorded in September 2020 in Villahermosa, Tabasco and in December 2021 in the Pichucalco area, Chiapas. Therefore, in this work an increase in its extension of approximately 50 km in three years is recorded. This progress could be considered slow, if we compare it with that of Pterygoplichthys spp, which in a few years made significant progress throughout the Grijalva-Usumacinta basin. To analyze this situation, it will be necessary to carry out studies on the possible causes. Conclusion. The speed of extension is slow, and the presence of A. pectinifrons extends over 50 km in the Grijalva-Usumacinta basin
