The blue dimensions of aquaculture: A global synthesis.

The rapid development of aquaculture has been considered the blue revolution, which is an approach to increasing global fish production in order to contribute to human nutrition and food security. The use of blue water (i.e., surface and groundwater) in aquaculture also makes a significant contribution to global fish production. However, the blue revolution of aquaculture is associated with a wide range of environmental concerns, including habitat destruction, water pollution, eutrophication, biotic depletion, ecological effects, and disease outbreaks. In addition, blue carbon (i.e., carbon in coastal and marine ecosystems) emissions from mangrove deforestation due to shrimp cultivation are accumulating. To increase fish production for a growing global population, aquaculture must grow sustainably while at the same time its environmental impacts must reduce significantly. There is blue growth potential for increasing seafood production through the expansion of coastal and marine aquaculture, which is essential for sustainable development of the blue economy.
