Description of Saccharina japonic a commercial stock in the Aniva Bay (Okhotsk Sea) //
Stock of Saccharina japonica in the Aniva Bay (Okhotsk Sea coast of Sakhalin Island) was surveyed by divers in 2010 and assessed with the squares method. The total stock decreased slightly as compared with the previous year (from 47,800 to 43,560 t) but the commercial stock became higher (42,410 t i...
