Economic values are used to balance the emphasis on breeding goal traits, and determine whether selection for a trait is worthwhile. The basic reproduction ratio (R0) determines transmission dynamics of a disease and, therefore, R0 is an appropriate breeding goal trait. This study presents an easy to use framework for the derivation of the economic value of R0 for macroparasitic diseases. An example for sea lice in salmon is provided, resulting in an estimate of R0 of 2.9 with an economic value of -0.072 €/unit R0/kg production. Keywords: Economic value, R0, epidemiology, disease
