- Evaluación de la calidad bacteriológica del alimento vivo (Artemia, Daphnia, Tenebrio y Tubifex) para peces en los sitios de su recolección, producción y venta Carmen Monroy Dosta Pilar Negrete Redondo Jorge Romero Jarero Multidisciplinaria (Ciencias Naturales y Exactas) ARTEMIA DAPHNIA TUBIFEX TENEBRIO LIVE FOOD Cichlids constitute the group of fi shes of greatest importance for ornamental aquaculture. To increment the production of thesespecies, producers have to satisfy the metabolic necessities that will give to the fi sh greater tolerance to the variations in thephysicochemical factors of their surroundings, as well as resistance to diseases. Aquaculturists include live food as part of theirdiet for its high protein content, mainly in their fi rst development phases. The organisms of greatest use in aquaculture as livefood are: Artemia, Daphnia, Tubifex and Tenebrio; nevertheless, and in spite of being a probable source of ichthiopathogenic contamination,the bacterial charge they carry is not considered, which is incorporated to the culture system with the food. For thisreason, in the present study a diagnosis of the sanitary conditions of live fi sh food management: Artemia, Daphnia, Tubifex andTenebrio, during its collection, production and selling process was done. A qualitative and quantitative analysis on the bacterialcharge in each one of these foods was performed. The isolated strains, in different specifi c microbiological agars, were purifi edand identifi ed using API-20E and API- 20NE systems. To establish the signifi cant difference between sanitary conditions anddefi ned bacterial charge, per food and per commercial process phase, an analysis of variance and the comparison test of multiplemeans by the method of Tukey was performed. Signifi cant differences in sanitary management conditions and in the count ofufc/mL different food samples were observed. In different phases of commercialization process three different levels were identified: good, bad and worst, according to the sanitary management and count of cfu/mL of each feed 2008 artículo científico 0301-5092 https://www.redalyc.org/articulo.oa?id=42339303 en http://www.redalyc.org/revista.oa?id=423 Veterinaria México application/pdf Universidad Nacional Autónoma de México Veterinaria México (México) Num.3 Vol.39
