【 摘 要 】

In 2014-2018 a study has been made on the development of bladder wrack (Fucus vesiculosus L.) coenopopulation in the tidal zone of the southwestern part of the Bolshoy Solovetskiy Island in the White Sea. During the observations, the dates of occurrence of germlings, dichotomy, air bladder, and receptacles on fucus thalli were established. The results of observations of F. vesiculosus development confirmed the data on the two peaks of germlings emergence. It was found out that the nature of fucus vegetative development in the first year of life is homophyadic. Further development of fucus in specific coenopopulations has its own biological features. The populations of F. vesiculosus are capable of renewal after 4 years. The results will be used to develop recommendations for the rational use of seaweed resources.
