Abstract

Diving surveys were conducted in the Avacha Bay, Kamchatka State, Far East Russia in 2012 and 2014, to research available macroalgal resources in this area. It was suggested that the major algal resource was the digit type kelp Saccharina bongardiana, which covered at least 50% of the rocky substrata within the depth range of 1-9 m. The standing crop of S. bongardiana was 11 kg m ^-2 and the mean blade length was 90.7 cm. Its length and wet weight reached their maximum in June, while sorus occurrence on the kelp surface was recorded in August and September. These results were compared with previous studies of kelp fisheries carried out in Hokkaido (Japan) and Sakhalin (Russia).
