Abstract

A mechanism that seaweeds collecting activities based on the collection calendar making a contribution to sustainable utilization of algal resources, was elucidated. The collection calendars were described through one year during 1995 to 2013 for analyzing the relationship between seaweeds collecting activities and sustainable utilization of algal resources at Choshi (35°73′N, 140°83′E) and Tateyama (34°98′N, 139°86′E) areas where the oceanographic conditions are different in Boso Peninsula, Japan. As a result, seaweeds collecting activities are minor subsistence as small occupation for the domestic and/or local consumption, though the collecting forms of seaweeds are different at two areas. Seaweeds have been collected without overfishing at seasons having high productive capacity all year round on the basis of knowledge of ecology of seaweeds, folk taxonomy and shallow water environment in many years of fisherman's experience. The fisherman's community takes a calendar of fisherman's daily life and the regional sociocultural events into the collection calendar of seaweeds. In fact, both the beginning and the end of seaweeds collecting activities depend on regional ceremony and festival as a signal. Sustainable utilization of algal resources as part of ecosystem services has been maintained on regional seaweeds collection as minor subsistence.
