Objective: To analyze through a scientometric study, the research effort in Mexico on the study of native and exotic fish species with aquaculture production technology, indexed in Scopus. Design/methodology/approach: Fish species were selected based on a previous study and communications with researchers. Scientific articles from 1990 to 2023 were collected from the Scopus database, focusing on studies conducted by Mexican institutions. Data were transferred to Excel® sheets for analysis, including number of publications, topics, institutions, funding sources and open access documents. Results: The species that shows the greatest number of articles published is Oreochromis niloticus, although there is a clear interest in addressing studies on native species. In general, scientific production is led by institutions such as UNAM, IPN, UABC, CIAD and CIBNOR. The dominant topics are aquaculture, ecology, biochemistry, immunology, and parasitology. CONAHCYT is the main source of funding. About half of the publications were open access. Limitations on study/implications: The study is limited to the Scopus database, which is the one that includes the largest number of journals worldwide. However, by not including other databases the results could have a slight bias, although we do not consider that the trends changed significantly. Findings/conclusions: Fish research in Mexico shows a positive outlook, with great interest in several species. However, it faces challenges such as the concentration of effort on exotic species, and the impact of the pandemic on research. A balanced approach is needed to encourage research on native species and facilitate open access to scientific information. This will strengthen fish research in Mexico and enhance its impact on the development of the country.

“…Su potencial económico mundial se ve reflejado en el aumento de la producción de 100,000 a 500,000 Toneldas anuales en las últimas décadas (ONU, 2014). Posee características distintivas para su cultivo, es un organismo muy resistente a fluctuaciones ambientales que puede vivir en un amplio rango de temperatura, además se adapta bien a diferentes sistemas de cultivos (Robinson et al, 2001;Lara-Rivera et al, 2015). El objetivo del presente trabajo es utilizar los subproductos del fileteo de tilapia Oreochromis niloticus para la elaboración de ensilado fermentado y llevar a cabo su caracterización parcial, así como evaluar su uso potencial como ingrediente mediante la inclusión en alimento para el cultivo del bagre de canal I. punctatus.…”

Los subproductos de acuacultura tienen gran potencial como ingredientes en la industria acuícola como fuente proteica para satisfacer requerimientos nutricios de organismos disminuyendo costo e impacto ambiental. Se elaboró ensilado fermentado (EF) con homogenizado de subproductos frescos (SPF) de 30 organismos de tilapia Oreochromis niloticus con 10% de yoghurt natural comercial y 15% de melaza. Se evaluó pH y acidez del EF, análisis proximal, perfiles de aminoácidos y ácidos grasos del SPF y EF, efecto del ensilaje en proteínas sarcoplásmicas y desempeño biológico de bagre de canal Ictalurus punctatus alimentado con 5 niveles de EF sustituyendo harina de pescado en dietas isolipídicas. El EF presentó valores de pH de 4.44 y acidez titulable de 1.32. Proteína cruda y grasa cruda en SPF y EF fueron 41.8% y 41.5% y 12% y 10.5 respectivamente sin diferencias significativas (P>0.05). El bagre de canal alimentado con 5% de EF presentó tasa de crecimiento específica de 2.94%/día, factor de conversión alimenticia de 1.38, supervivencia de 84.07% y factor de condición K de 0.87, sin diferencias significativas (P ≤ 0.05) en comparación con la dieta de 0% de inclusión. Los resultados muestran la factibilidad de sustituir hasta 5% de harina de pescado por EF de subproductos de tilapia como ingrediente proteico, sin afectar el crecimiento y supervivencia de bagre de canal.

Mexico is the native site of 10 species of the genus Ictalurus, among which the Channel Catfish I. punctatus has great presence in worldwide aquaculture. Wild populations of catfish not only constitute a biological resource but have a great potential for aquaculture. Recently, this species was classified as an invasive organism by the Mexican government. The aim of this study was to determine the structure and genetic diversity of Channel Catfish belonging to native and introduced freshwater populations within Mexico. Using 11 DNA microsatellite loci, we analyzed 292 fish sampled from four rivers and five reservoirs. Observed heterozygosity values ranged between 0.66 and 0.80. The genetic distance analysis showed low to high differentiation among populations (overall genetic differentiation index FST = 0.14). Bayesian coancestry analysis identified two ancestral groups. A single management population on central Tamaulipas can be suggested. The findings of the present study provide the basis for future characterization of productive traits of Mexican Channel Catfish populations in order to use the species as a breeding source for aquaculture. The lower Rio Grande population is one of the most ancient and ecologically relevant Channel Catfish populations in Mexico, and this study identifies it as the most vulnerable. Free‐living populations of Channel Catfish, although they have been heedlessly spread, constitute a valuable natural resource that deserves our best effort to preserve.
