The simple ratio estimate of the total number of marked fish present in a catch is described and the variance estimates discussed. A maximum likelihood estimate of the total number of marks present in a catch is derived which combines both marks found in samples and marks voluntarily returned from the non‐sampled portion of the catch. The use of this estimate is illustrated with data from the salmon sport fishery in Puget Sound.
