Abstract: Known as the major marine shellfish aquaculture country in the world, China has paid much more attentions on the marine biological industry, public health and nutrition requirements. High value utilizations of marine shellfish and their byproducts is the mainstream focus point of the marine development and management. Glycosaminoglycan is an important marine shellfish substance that has many bioactive properties, including anti-clotting, hypolipidemic, anti-tumor, anti-oxidation, strengthening immune system, etc. The current stage of knowledge on the marine shellfish glycosaminoglycan is reviewed in various aspects: extraction, isolation, purification, characterization and biological activities, which lays the foundation for the fine processing and comprehensive utilization of shellfish and its cooking liquor, as well as providing scientific basis for the developments of marine shellfish resources utilization and marine health care products.
