The invention discloses a method for comprehensively utilizing euphausia superba shells. The method is a comprehensive utilizing method, wherein the shells are hydrolyzed by means of endogenous proteinases and exogenous alkaline proteinases of euphausia superba with high activity based on euphausia superba shells as raw materials to recover proteins and astaxanthin, while residues are used for producing chitin. The shells are hydrolyzed by means of endogenous proteinases and exogenous alkaline proteinases, so that the protein recovery rate is effectively increased. Enzymatic hydrolysates are filtered and centrifugalized, and the filtrate is concentrated to obtain protein concentrate or sprayed and dried to obtain soluble protein powder. The protein content in the protein powder is 75-85%. Precipitates are freezed and dried to obtain the protein powder rich in astaxanthin, wherein the protein content is 50-60% while the astaxanthin content is 600-900mg/kg. The addition amount of exogenous enzymes is reduced by 40-50% by replacing part of exogenous enzymes by enzymolysis of endogenous proteinases in a way of combining the characteristic that the endogenous proteinases of the euphausia superba are high in activity, so that the cost is greatly lowered.
