The Normandy region is presently a leading shellfish rearing area in France yielding 35,000 metric tons of oysters C. gigas and Il,000 metric tons of mussels M. edulis on a yearly basis. Preliminary studies were initiated in 1989, 1991 and 1992 to develop the sampling strategy for cultured mussel stock assessment. Comprehensive mussel stock assessment and concomitant growth monitoring were carried out in 1993 to study mussel population and optimize overall s1l1ellfish culture management.  A three-stage cluster sampling strategy combined with stratification was tested on the 278 kms 'bouchot' type culture with a sampling effort of 275 units. Stratification was based upon two criteria including geographical sector and tidal level. Overall biomass was...
