It seems, however, that the confusion about wild and farmed fish increases with age (data not shown), since the reported consumption of wild fish decreases with increasing age, which is the opposite trend compared to reported overall fish consumption. The data shows that on average the consumption of fish increases with increasing age in all countries except Poland where differences in consumption frequencies were not significant across age groups. The finding of increasing fish consumption as age increases confirms earlier European studies of fish consumption.
Huge differences regarding preferences for fish species
The preference for fish species varies quite a lot between the countries as shown in Figure 2. In Belgium, cod and salmon are the most frequently consumed species, while the Danish seem to prefer herring and tuna. In The Netherlands, tuna and salmon are most frequently eaten, in Poland it is herring and mackerel. Finally, in Spain, tuna and hake are preferred. Herring seems to be most popular among the older consumers, while tuna was most often eaten by the youngest.
