Abstract
    The validity, reliability and practicability of different methods for the investigation of stomach contents of a small, plankton-eating fish are discussed. Tests demonstrated the problems related to mass and volume measurements of planktonic food. Several nutrition indices, particularly Hynes's “frequency of occurrence” are criticized. A logarithmic version of Shorigin's index is proposed as a replacement for Ivlev's food selection index. A preliminary study on the food of Gobiusculus flavescens (Fabricius), sampled in July, 1975 at Helgoland, provides some numerical information on the composition of its stomach contents and food preference.
