Fish is one of the most valuable renewable marine resources and plays a vital role in global food security, employment, trade, and the economy. Oceans account for the majority of the world's fish production, while inland water bodies also contribute significantly. The distribution of fishing regions depends upon factors such as the availability of nutrients, ocean currents, continental shelves, water temperature, plankton abundance, and technological development. The most productive fishing grounds are generally located in shallow continental shelf areas where nutrient-rich waters support abundant marine life. The North-West Pacific is the world's largest fishing region. It extends along the coasts of China, Japan, South Korea, and Russia. The convergence of the warm Kuroshio Current and the cold Oyashio Current creates ideal conditions for plankton growth, which supports rich fish populations. Important species include sardines, tuna, mackerel, salmon, anchovies, and pollock. Advanced fishing technology and a large coastal population further enhance the productivity of this region. The North-East Atlantic is another major fishing area, extending from Portugal to Norway and Iceland. The shallow continental shelf, particularly the North Sea, Barents Sea, and Norwegian Sea, is highly productive due to nutrient-rich waters and favorable climatic conditions. Cod, herring, haddock, mackerel, and plaice are among the principal catches. Countries such as Norway, Iceland, the United Kingdom, and Denmark have developed strong fishing industries in this region. The North-West Atlantic includes the Grand Banks of Newfoundland, Georges Bank, and coastal waters of eastern Canada and the United States. Historically, it has been one of the richest fishing grounds because of
