Synopsis
The optimal density of plankton required for the growth and development ofCoregonus lavaretus (L.) larvae is calculated on the basis of the volume of water searched, the probability of successful feeding responses, and the results of experimental growth studies. This amounts to 200–260 individual food organisms 1−1 (individual plankton 0.004 mg), or 14–17 individuals 1−1 (individual plankton 0.057 mg). The feeding optimum depends on water temperature and the time at which feeding begins.
