The aim of this research was to establish whether the dietary preferences of perch (Perca fluviatilis L., 1758) change due to age and the seasons. Food items were examined by the Geometric Index of Importance (GII) method. The results obtained from this index were also evaluated in relation to seasonal and age-dependent variables. It was observed that the dietary preferences of perch do not change with age and the seasons.

In this study, 239 perch which had been caught between May 1998 and December 2000 from Derbent Dam Lake with a number of different nets, shockers and tackles were examined. The organisms obtained after analyzing the perch stomach contents patterns were examined by means of the Geometric Index of Importance (GII). As a result, a total of 27 food items (19 of which were plant and eight animal) were found in the stomach contents. The percentage of plant diet was 6% and that of animal diet was 94%.

Aged-Based Food Preferences Of Common Carp (Cyprinus Carpio L., 1758) Inhabiting Fish Lakes In The Bafra District Of Samsun Province (Lakes Tatlı And Gıcı), Mahmut Yilmaz, Aysun Gümüş, Savaş Yilmaz, Nazmi̇ Polat

Turkish Journal of Veterinary & Animal Sciences

The stomach contents of 122 common carp (Cyprinus carpio L., 1758) individuals collected from lakes Tatlı and Gıcı between January 2000 and December 2000 were investigated. The Geometric Index of Importance (GII) was used to determine food preferences among individuals and to assess whether these preferences were age based. It was concluded that the diet preferences of the common carp were not dependent on age and comprise a wide variety of food items present in their natural habitat. The results are presented in tables and figures.
