The present work is a review of the literature on the native Mexican fish Dormitator latifrons. The aim is to contribute to the integration and systematization of current knowledge to make it easier to identify existing knowledge gaps and breakthroghs Moreover, promote the successful cultivation and protection of this species whose consumption is increasing in Latin America. A review of the articles related to D. latifrons published in international and regional databases was carried out. The articles reviewed focus on taxonomy and systematics, phylogenetic, geographic distribution, ecology, physiology, reproduction, development, pathology, health, and the technologies used to cultivate this fish species. The conclusion is that, even though the cultivation of D. latifrons is of commercial interest in some countries, there are still significant gaps in our knowledge of biology and, consequently, the domestication potential of the species. Filling these gaps will require systematic research efforts on protecting natural populations and improving mass cultivation techniques.
Dormitator latifrons is an amphidromous fish species distributed on the Pacific coastal region from California to Peru. It has a high potential to be cultured in Mexico. However, there is very little information about its biology, physiology and culture. This research study is a contribution to the hematology and blood chemistry of this native species. Results show hematocrit values of 28%, erythrocytes 2.075×106 mm3, leukocytes 35.035×103 mm3, mean corpuscular volume 161.547 fL, NBT 0.39, glucose 51.467 mg dL-1, protein 3.936 g dL-1, albumin 1.906 g dL-1, globulin 2.391 g dL-1 and albumin/globulin ratio 0.686.
Un pez nativo cada vez más estudiado en Latinoamérica es el Dormitator latifrons, pero se desconoce el efecto de altas densidades de siembra en su fisiología. El objetivo fue determinar el efecto de diferentes densidades de siembra en el crecimiento y parámetros sanguíneos. Se utilizaron organismos silvestres aclimatados al cautiverio, alimentados al 4% de biomasa total durante 60 días. Se registró peso y longitud inicial y final, determinando índices de crecimiento y supervivencia. Al final del experimento se tomó una muestra de sangre al total de organismos para evaluar parámetros sanguíneos No se encontraron diferencias en el crecimiento y supervivencia entre las diferentes densidades. Los parámetros sanguíneos no fueron afectados por la densidad, a excepción del estallido respiratorio, todos se encuentran entre los rangos de referencia de buena salud para peces. La especie no presentó señales de estrés o respuesta inmune adversa asociada al incremento de la densidad de cultivo.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
