Résumé

Synopsis: Ecological fish production of 30.8 kg ha?1 yr?1 was estimated for a 6.2 ha Precambrian shield lake by treating it with a piscicide and removing all fish. This is one of the lowest productions recorded for any waterbody.Perca flavescens contributed 71% to this total. The five other indigenous species werePimephales promelas, Semotilus margarita, S. atromaculatus, Notemigonus crysoleucas andSalvelinus fontinalis. Seventy-five percent of the production occurred in the first year of life. A conventional capture-mark-recapture experiment conducted onP. flavescens prior to the piscicide treatment underestimated the density by nine times and the total production by eight times. The gravest error occurred in the estimation of density for the younger age groups. Production studies can quantify the ecological success of a species, and provide a measure of stress in aquatic ecosystems.
