Sea Cucumber of north Atlantic: Approach to the potential of new sea resource
Sea cucumber is a marine resource that is little or not used in portuguese and European diet, in contrast to what happens in asia, where these animals play an important role as a food resource (high nutritional value) and also in traditional medicine (as a nutraceutical important source). So, sea cu...

Sea cucumber is a marine resource that is little or not used in portuguese and European diet, in contrast to what happens in asia, where these animals play an important role as a food resource (high nutritional value) and also in traditional medicine (as a nutraceutical important source). So, sea cucumbers have been subjected to more extensive research all over the world. The value of the sea cucumber as a potential marine resource in Portugal and Europe, was the main goal of this thesis, as a contribution to generate initial data on the nutritional and nutra- ceutical quality of the species present on the portuguese coast.
