Summary Observations were made of characteristic nursery areas along the southern and western coasts of Lake Kinneret, Israel, during the years 1982–84. Cyprinid and cichlid fingerlings were found to have different specific habitats. Most cyprinid species are of palaearctic origin, and prefer low water temperatures. Fingerlings of some species of cyprinids have exclusive habitats. A common characteristic of all the species is the direct relationship between body size and water depth. The presence of cichlid fingerlings in the nursery areas during the day is directly related to the occurrence of sunlight and to water temperature. An important finding was the time of dispersion of the cichlid fingerlings, which is when they attain a size ˜ 5 cm and weight of ˜ 3 g. Stocking of the lake with cichlid fingerlings below 3 g is not recommended.
