The production of fish-protein hydrolysates (FPHs) has been envisaged as an alternative to the upgrading of underutilised fish species and fish byproducts. FPHs were mainly intended for animal or human nutrition and also as a nitrogen source for microbiological growth media. The production of FPHs represents an improvement in fish ensiling, where the hydrolysis process did not depend on the endogenous fish-protease activity. This chapter reviews protein-derived bioactive peptides obtained from the proteins of fish, shellfish and other aquatic organisms. Particular attention is given to the amino acid sequences of the bioactive peptides isolated and purified from the protein hydrolysates obtained under different hydrolysis conditions. The biological activities of FPHs discussed include hormone-regulating activity, immunostimulant activity, anticoagulant activity, appetite suppression, calcium-binding peptides, antimicrobial and antiviral activity, anticancer activity, antioxidative property, and angiotensin i-converting enzyme inhibiting activity.
