Iii this study. Northern Pike larvae's digestive tract contents were examined inhabiting in Isaszeg reservoir lake. Hungary. In totally 19 thousand varieties of nutrients were found out. 12 of them derived from zooplankton and 7 of them from phytoplank- Ton. Northern Pike larvae's constitutive nutriment sources were zoological originated. Geometric Importance Index (Gil) were highest for Bosmina sp. with 1097.49 in this specie's larval nutrition. This was followed by Chydorus sp. (503.836) and Ther- mocyclops sp. (493.299) respectively. Pike starts to exogenous feeding at 12 mm length. In contrast to GII. Selectivity index (SI) were revealed that Ther- mocyclops sp. were preferred by pike larvae as the main food organism. © by PSP.
