dc.description.abstract | The Joaquín Costa reservoir contains a mixed fish assemblage of native and
exotic species. Feeding habits and feeding relationships of species in the fish assemblage were
analysed over a one year cycle. Differences in diet composition were found both between
species and within species among seasons. Food overlap and trophic similarity among species
also showed seasonal variations. Cluster analysis differentiated four groups of predominant
diet: (1) macroinvertebrates (trout and largemouth bass), (2) detritus (nase), (3) cladoceran
crustaceans and (4) an omnivorous feeding regime, with large seasonal variations in food habits.
Food of fish species included in groups 3 and 4 (roach, white bream, barbel, common and mirror
carp) varied seasonally. Using graphical models of feeding strategies, similarity indexes, cluster
and multivariate analyses based on the relative importance of food categories in the diet of the
species, we illustrate that the fish assemblage showed food resource partitioning according to
food habits and foraging habitats within the reservoir. | es |
