Seaweed represents an important economical resource in Indonesia. They are potentially as good source of nutrient. Furthermore, they have the most nutritious and rich in mineral than any other feedstock. The levels of minerals are ten to twenty times from total mineral content of terrestrial plants. This experiment was carried out to evaluate the nutritional value and mineral content of several seaweeds namely Caulerpa, Palmaria and Ulva, in order to utilize as fish feed ingredient. Seaweeds were collected from Binuangeun Beach, Banten and south coast of Java Island. Carbohydrate by different (NFE) and ash contents were the most two abundant components. Seaweeds Caulerpa, Palmaria and Ulva contained 44.73%, 53.74%, 55.31% NFE; and 27.36%, 22.81%, 20.51% ash based on dry weight, respectively. These contained high amounts of Na, K, Ca, and Mg ranged 0.72-5.65 g 100g−1, Fe, Mn, Cu, and Zn ranged 2.09x10−4-0.09 g 100g−1. The quantity of the bio-essential elements (Fe, Zn, Cu) followed as Fe>Zn>Cu. The iron content was rich in the sequence of Caulerpa>Palmaria>Ulva and its range was found to be 0.01-0.09 g 100 g−1 in dry weight. The result showed that Caulerpa, Palmaria and Ulva are valuable resource and potentially to be utilized as fish feed ingredient.
