lautnusantara.comFish and fishery products are among the most important sources of animal protein, especially in maritime countries like Indonesia. Their high nutritional value, delicious taste, and abundant availability make fish a strategic food source in efforts to improve community nutrition. Moreover, the advancement of fish processing technology has expanded the variety of fish-based products available in fresh, frozen, dried, canned, or ready-to-eat forms.


Nutritional Content of Fish

Fish are known for their high-quality protein, complete with all essential amino acids. Key nutrients found in fish include:

  • Protein: 16–22 g per 100 g
    Supports muscle building, hormone and enzyme production, and immune function.

  • Omega-3 Fatty Acids (DHA & EPA): 200–2,000 mg per 100 g
    Play a role in brain development, heart health, and inflammation control.

  • Vitamins:

    • Vitamin A: essential for eye health

    • Vitamin D: supports calcium absorption and bone strength

    • Vitamin B12: aids in nerve function and red blood cell production

  • Minerals:

    • Iodine: prevents goiter and supports thyroid function

    • Selenium, phosphorus, and iron: vital for metabolism and immunity
