anglais. Macrophytes have become a major problem in some shallow aquatic systesm, largely as a result of the eutrophication. Uncontrolled growth of these plants can cause damage and economic loss to irrigation and drainage systems, and, if they block pump intakes, disrupt the operation of hydroelectric power plants. The background and the means for biological control of aquatic weeds which are of practical significance are discussed. The most effective direct effort at developing biological control methods has been the herbivorous fish Ctenopharyngodon idella Val. The current state of knowledge on the biological and ecological characteristics of this species are reviewed. We propose a methodological approach, comprising different steps, to be adopted in undertaking a programme of biological control with this species.

La presenza di una notevole biomassa di acrofite acquatiche puo determinare in alcuni corpi idrici, ed in particolare nei bacini degli impianti idroelettrici e nei canali egli impianti di irrigazione, l'insorgere di problemi gestionali non indifferenti. Nel presente articolo dopo un richiamo alle basi concettuali del controllo biologico, vengono esaminati gli aspetti connessi all'utilizzo della carpa erbivora (Ctenopharyngodon idella Val.), per tale controllo. Particolare attenzione e stata dedicata agli aspetti metodologici connessi alla pianificazione del controllo.
