The limiting factor for inducing the spring bloom of phytoplankters in 1980 at Tsuchiura Harbor of Lake Kasumigaura was temperature. The bloom started at a water temperature higher than 10.degree. C and lasted until the temperature was up to .apprx. 20.degree. C. The concentration of inorganic N in the lake had a profound effect on the induction of the spring bloom as a nonlimiting factor. Other inorganic nutrients contributed mostly to the species succession of phytoplankters comprising the spring bloom.
