Fisheries depend on the natural cycle of matter and biological productivity in the ocean. This includes not only the capture productions of wild animals and plants, but also the aquaculture productions of seaweeds that depend on natural nutrient cycles, bivalves depending on phytoplankton and particulate organic matter, and finfishes depending on captured fish stocks. Conservation of coastal and offshore ecosystems and maximization of their biological productivity have fundamental importance for the capture and aquaculture productions to get rid of the stagnation of the last two decades.
