Census ( N C ) and effective population size ( N e ) were estimated for a lake‐resident population of brown trout Salmo trutta as 576 and 63, respectively. The point estimate of the ratio of effective to census population size ( N e : N C ) for this population is 0·11 with a range of 0·06–0·26, suggesting that N e : N C ratio for lake‐resident populations agree more with estimates for fishes with anadromous life histories than the small ratios observed in many marine fishes.
