de la nourriture, en quatre grand groupes écologiques: espèces planctonophages(P), espèces benthophages(B), espèces piscivores(C) et espèces euritrophiques(E). L`évolution du nombre total d`espèces capturées industriellement, d`espèces à l`importance économique, de captures totales et des groupes trophiques présentes dans la zone étendue entre Braila (le km 170) et Giurgeni (le km 232), est analysée à l`aide des différentes périodisations situées entre les années 1952-2007 pour pouvoir observer le sens et la magnitude dans lesquels la structure de la population piscicole s`est modifiée.
