Due to advances in marine observation and calculation devices, in recent years marine weather forecasting has been vigorously carried out with the result that it is now also being used for ship weather routing. The importance of marine data derived from observations and numerical calculations should continue to increase in the sustainable use of the ocean. In this article I would like to discuss the uses of marine data and introduce as an example the initiatives being undertaken in sailing competitions, one of the Olympic sports.

While calls continue for the sustainable use and conservation of the world’s decreasing marine life resources, there has been a rapid increase in their demand. The aquaculture industry, as a major supplier of marine products, especially of fish, is being called upon to practice sustainable use that will reduce impacts on natural resources to the lowest level. The seed certification system aims at sustainable marine aquaculture and the provision of marine products by being the driving force behind the switch from natural to artificial seeds, the crucial element for aquaculture.

Lures are designed based on research into the target fish’s life and habits, intended to match with a particular species as closely as possible. In other words, if the target fish changes, so should the lure; the performance required of the fishing rod could also change completely. Recently, fishing has been changing from a means of acquiring food to a sport in which enjoyment of the process itself is the object. We believe that educational activities to promote conservation of fishing environments are also a responsibility of developers.
