Abstract Sampling variability of ichthyoplankton at a single sample site was investigated. The major sources of variance were identified as seasonal (differences over days), diurnal, tidal and gear. Patchiness of plankton was not recognized as a significant source of variance in this study. No relationship between net avoidance and velocity of two was demonstrated. However, different avoidance responses from fish larvae and zooplankton were found. The above-mentioned methodology is and results are described in detail. The mechanical flow meters used were found to perform in an acceptable fashion. Sampling 100 cu m of water is inadequate to collect density data for some species.
