Abstract
The paper presents the results of the observations on certain 
environment factors, during 1971 in a zone with macrophytic 
associations on the Romanian Black Sea shore. The following
measurement data are included: light, suspended matter, water
temperature, salinity, organic matter, dissolved oxigen, phosphates,
and biochemical oxigen demand. All these measurements and
observations, correlated with certain data on the biology of some
marine benthic algae, particulary of the Cystoseira sp., showed
that during 1971, particulary favourable conditions were prevalent
on the Romanian sea shore for the increase of the marine benthic
algae stock.
