In many developing nations, fish and fish products, being a cheap and rich source of proteins, lipids and other nutrients, constitute most of the animal protein, consumed by the poor. Thus, due to the rising population, there is a large and growing demand for fish. The Indian subcontinent is one of the world’s largest fisheries, with the southern peninsula contributing to approximately 51% of the total fish landings in India. The major fish catch for Tamil Nadu and Kerala, the two prominent fishing states in the southern peninsula, is through artisan fishermen. A survey of artisan fishermen in 6 villages in Tamil Nadu showed they were poor, had inadequate housing and little reserved capacity to meet adversity. The survey revealed that fish catch per person has significantly reduced in the last 50 years.
Ocean Nourishment, the enrichment of sea water with nutrients, could be used to increase the primary productivity which will result in substantial increase in fish stocks and the sequestration of atmospheric carbon dioxide. If nitrogen is introduced into the barren zones of the ocean, it could increase fish biomass similarity to nutrient upwelling. A strategy for increasing the number of fish, available to the growing number of artisan fishermen is proposed. The implementation of Ocean Nourishment could spark the Blue Revolution in India and aid in the overall upliftment of the standard of living of the poor fishermen of India.
