First record of a bloom of filamentous-heterocystous nitrogen fixercyanobacterium, Aphanizomenon ovalisporum, was documented in the summerof1994 inLake Kinneret Israel. Awareness of such a bloom outbreak was predictedearlier based on documentation of Nitrogen deficiency and PhosphorusSufficiency developed conditions. The concept of Nitrogen fertilization aimedat suppression of Nitrogen fixers Cyanobacteria was worldwide discussedand successfully implemented, but mostly in temperate oligotrophic lake ecosystems.This paper presents an experimental testing of this concept by additionalNitrogen. The results of the present study did not verify this hypothesisprobably related to the ecological differences between Kinneret and thetemperate ecosystems and using only one factor Nitrogen to test it.
