The lengths of individual shellfish in a population of 10000.
From these surveys, the mean shellfish serving sizes for shellfish consumers were 106 g for adults and 49 g for children (Cressey et al. 2006). A more recent NNS of adults was conducted in 2008/09, but at the time of this research, individual record data to calculate shellfish consumption were not available (Ministry of Health 2011).
