This study describes the abundance of exotic amphipods associated with aquaculture systems and their possible use as animal food. Of the six amphipod species recorded in fish aquaculture systems, Jassa marmorata (Holmes, 1903) is the most abundant. Differences were established in the species' abundance and between sites; however, no variation was observed in species composition. Feeding trials were carried out on paralarvae of the “baby octopus” Robsonella fontaniana (d'Orbigny, 1834) to determine the potential use of Jassa marmorata as animal food. El estudio describe la abundancia de anfipodos exoticos asociados a sistemas de acuicultura y su posible uso en alimentacion animal. De las seis especies de anfipodos registrados en sistemas de cultivo de peces, la mas abundante fue Jassa marmorata (Holmes, 1903). Se establecieron diferencias en la abundancia de las especies y entre lugares de los sistemas de cultivo. Sin embargo, no se registraron variaciones en la composicion de las especies. Se realizaron pruebas de alimentacion con Jassa marmorata en paralarvas del “pulpito” Robsonella fontaniana (d'Orbigny, 1834), para determinar su uso potencial como alimento.
