This part of the current study concerned with the growth analysis of the major biochemical elements in C. filosa (Crustacea: Amphipoda) reared in the laboratory aiming to indicate its nutritional value as life feed, the results clear that adults individuals, which has been breeding in the laboratory and also juvenile's, Contain high levels of total protein, total lipid, than individuals collected from the field, while total sugar ratio was in the field is higher than individuals in the laboratory. The main reason that its nutrition through different species of microalgae which contain high ratio of nutritional value. In adult cultured the highest value of essential than value nonessential of amino acids but The culture of juvenile's the highest value of nonessential than value of essential amino acids.

The level of polyunsaturated fatty acids (n-6 PUFA) in adult cultured and juvenile's culture (0.69 mg/g) higher than field sample (0.50 mg/g),and The total level of saturated fatty acids (SFA) in cultured adult is (105.61 mg/g) higher than culture juvenile's (99.17 mg/g) and field sample (15.98 mg/g)
