Oceanographic environmental information is critical to understanding the interaction between marine fish, which are an important ocean resource, and their environments across multiple life-history stages. The concept of environment must be understood very broadly in this regard. It includes not only the other components of the trophic network in which fish are found, but also all the surrounding components of inanimate nature. The future of interactions between living but also non-living parts of the environment depends on changes in the oceans. The provision of routine oceanographic information needed for decision-making purposes is dependent on sustained research and development, from observation collection to delivery mechanisms.
