Introduccion: El conocimiento relacionado con el consumo de pescado es de vital importancia para establecer estrategias que permitan mejorar su consumo en esquemas de alimentacion saludable. Objetivo: Identificar preferencias y frecuencia de consumo de pescados y mariscos en estudiantes universitarios de la ciudad de Medellin, Colombia. Materiales y metodos: Se utilizo un tamano de muestra de 400 estudiantes, con base en un nivel de confiabilidad del 95% y un error maximo permisible del 4,9%. Los estudiantes fueron seleccionados aleatoriamente  de acuerdo con los factores de ponderacion: sexo, nivel socioeconomico y tipo de universidad y fueron entrevistados personalmente. Se realizo analisis factorial de correspondencia multiple con clasificacion jerarquica indexada y analisis multivariado de la varianza MANOVA con contraste canonico de tipo ortogonal. Resultados y conclusion: Se encontro que las especies de mayor preferencia entre los universitarios son atun, bagre, tilapia, trucha, robalo y camaron; los de menor preferencia son: lenguado, perla, arenque y corvina. Se encontro diferencia estadistica (p<0,05) entre sexos en el consumo regular de pescado; los hombres manifiestan un consumo semanal de calamar y sardina, mientras las mujeres consumen semanalmente atun, bocachico, langostino, ostras y pargo.
