Contenuti Stomacali della Fauna Ittica


Abstract


En
Dietary information from the examination of stomach contents of fish fauna of the Acquatina lake, were obtained. Four stations with different environmental conditions were sampled from April 2006 to April 2007, using fyke nets. The fish fauna showed a tendency to euriphagy. The high coefficient of repletion, determined for each species, showed high food availability in the basin. Atherina boyeri, Sardina pilchardus, and Engraulis enchrasicholus constitute an important resource for many predators in the Acquatina basin. The Sorensen index showed a high dietary overlap for some species (> 0,50) which indicates that the species are probably in competition for preys.
