Vertical distribution and morphological characteristics of Saccharina spp. at the coast of Gangneung-si, Gangwon-do, Korea

Since the introduction of Laminariales populations in Korea in the early 1970s for the purpose of aquaculture, Saccharina population was found on the east coast of Korea. The morphological characteristics and vertical distributions of Laminariales were studies and measured at different depths of the coast of Gangneung-si, Gangwon-do, Korea. In general, three species of Laminariales in the Gangneung coast were found to be distributed in different depth zone and divides three distinct transitional regions. Saccharina japonica var. religiosa and Saccharina japonica populations were studied to grow at depths of 3m and 9m, respectively. Saccharina sculpera population was found to grow at a depth of 20m. Maximum growth of S. japonica var. religiosa and S. japonica populations occurred in May and the blades decreased during summer season.
