Abstract
The Macroalgal flora of the Transition Zone of the eastern part of the Gulf of Finland was studied between 2003 and 2008. Sixteen species were found from a depth of 0.5–5 m. Three species (Cladophora aegagropila, Pseudolithoderma subextensum and Hildenbrandtia rubra) are listed as rare in The Red Data Book of Nature of the Leningrad Region (Tzvelev, 2000). Nine species are recorded here for the first time in Transition Zone of eastern Gulf of Finland. The dominant species growing at a 0.5–1.5 m depth was the green alga Cladophora glomerata. Our study shows that in 2003–2008 in the shallow (0.5–1.5 m) zone of the eastern Gulf of Finland, the biomass of C. glomerata peaks several times in a season reaching 450 ± 130 g DW m−2. Our study corrects earlier data for the species composition of macroalgae and describes their depth and horizontal distribution in the Gulf of Finland.
