Abstract
Some of the special conditions implied in the blooms phenomena
are presented. Information on physical, chemical and biological 
conditions throughout 1975-1982, along the Romanian marine inshore
waters are used. A comparison between the present state of phyto-
planktonic community and the state that had existed twenty years
ago, was done. The blooms of the most common species, the development
of this phenomena, its dependence by physical and chemical factors,
are discussed. In high eutrophicated waters a stronger dependence
of phytoplanktonic blooms by physical than common chemical factors
(P-PO4, N-NO3)seemed to be obviously.
