On the growth acceleration by iron fertilizer on algae enhancement technology

摘要

Summary form only given. Fishery resources in the world are decreasing year by year. One of this reason is over catching, on the other hand, change of habitable environments caused by pollution, global environmental change can be pointed out. Especially, living environment of the plankton deteriorates. Algae enhancement technology is, therefore, the most important for improvement of the living environment of plankton. Our special point is to use ocean fertilizer technology, especially, by a throwing type of iron fertilizer. Our object in this paper is to apply algae enhancement technology to a real ocean zone by using iron fertilizer.
