Abstract:

Counts of viable heterotrophic bacteria, Vibrio-like bacteria and total coliforms were performed in seawater supply, food stocks and broodstock pools at two aquacultural families located in Mexico. The high abundance of these bacterial groups indicates risk areas that must be monitored to control potential pathogens, such as Vibrio spp. Filtering systems and food supplies, such as Artemia spp. and fresh or frozen sea food, were found to be the most important sources of potential pathogens.
