Abstract

The aim: Stock assessment of commercial algae and seagrasses in the sea waters of Russian Federation and their fishery in 2000–2020.Method: The present article is based on original and statistical data obtained in 2000–2020 in accordance with standard methods of fisheries research.Novelty: The analysis has revealed the present status of commercial algae and seagrasses resources in the seawaters of Russian Federation as well as the reasons for low exploitation rates of these resources.Result: Algae and seagrasses resources in the seawaters of Russian Federation have hardly changed during last 20 years and remain stable.
