Abstract: Aquaculture is of vital importance in the generation of food of high nutritional value, employment, and economic income for the population, as well as an important role as a source of inputs for the country's food and currency industry. The objective of the present study was to determine the health status and presence of pathological agents causing parasitic disease in Channel Catfish (Ictalurus punctatus) on farms in the state of Tamaulipas, Mexico, through fresh pathology and Histopathological analyzes. One of the main problems facing this activity are diseases, which play a very important role since it affects in large range the production of Channel Catfish (Ictalurus punctatus), in Mexico and thus cause high mortalities in young organisms as well as to generate large economic losses for aquaculture. These represent an important factor in the loss of production and generate economic losses which also inhibit imports and exports of food products derived from production. During the years 2013 and 2014, 176 catfish samples (Ictalurus punctatus) were analyzed from farms located in the state of Tamaulipas, to identify the presence of parasites. Through the techniques of fresh parasitoscopy and histopathology, the main parasites identified were Henneguya spp. (80.1%), Trichoidna spp. (60.2%), Dactylogyrus spp. (37.5), Gyrodactylus spp. (27.3), Ichthyophthirius multifiliis (44.3%), Diplostomum spp. (38.6%) and Centrocestus spp. (23.3%). All the farms analyzed were found to be parasitized
