Abstract
    A comprehensive sampling exercise was carried out at Cordemais Power Station during 1988 in order to evaluate the number of 0-group flounder, Platichthys flesus, removed from the Loire Estuary by the water intakes. Larvae drawn through the cooling system and juveniles impinged on the drumscreens were both taken into account. Statistical confidence limits of the estimates (which are useful for comparisons with the effect of other human activities) were estimated using non-linear regression and Monte-Carlo techniques. The method was developed for one of the two similar units working during the April-June period of high flounder abundance in the cooling water. For this unit 16.5 million fish were drawn through the cooling system and 1.13 million were trapped on the drumscreen. The effect of the Power Station is discussed in connection with small-meshed fisheries and assessments of the estuarine juvenile stock.
