| At present, the majority of fisheries are monitored and regulated in areas which are delineated by arbitrary ICES boundaries which do not necessarily have logical or consistent relationships with biological processes or fish movements. The biogeographical identification of Channel stocks is, therefore, an important step towards developing a rational strategy for the management of their fisheries. This synthesis is based on the wide available knowledge which has not been yet entirely exploited with the purpose of stock identification, for 25 commercially important species in the Channel. In addition, principal technics for stock identification are reviewed likewise environmental characteristics of the Channel, which represent fundamental components in... |

| Today, it is commonly accepted that C. angulata and C. gigas are a single species according to morphological, genetic and experimental hybridization data. Following the viral disease that affected C. angulata and the subsequent expansion of C. gigas in Europe, it was of interest to examine the geographical distribution of both taxa in Europe. We studied the genetic composition of seventeen populations of cupped oysters, sampled in France, Spain, Portugal, Morocco and Italy, using a diagnostic marker, the mitochondrial Cytochrome Oxydase I gene. Results showed two distinct geographical zones. All the populations located in the northern part of the European sampled zone were mainly composed of C. gigas haplotypes whereas populations from southern Europe and... |
