Natural feed such as Sea Worms (Nereis sp), Shellfish, Squid, and Earthworms are often used for penaeid shrimps reproductive growth. These include vanamei shrimp because they have sufficient nutritional content. However, the use of natural food has many disadvantages, as its availability is very limited and depends on the season. Sea worms are a vector of disease carriers, especially viruses and bacteria. Nutrients needed for reproductive growth and development are protein, fat, carbohydrates, vitamins and minerals other than water. Squid flour, sea worm flour, and shellfish flour are used in artificial feed. It contains nutrients in accordance with shrimp brood stock reproductive growth. It is an alternative substitute for fresh feed which has limitations and disadvantages. Consequently, the protein content of squid flour (Loligo. Sp), shellfish flour (Ostrea. Sp) and sea worm flour (Nereis. Sp) was 73.87%, 59.97%, and 54.35%. The total amino acid content was 69.20%, 56.66%, 50.75%, respectively. The total fatty acid content was 35.22%, 44.65%, and 22.87% respectively.
