Approximately 50% of the aquaculture production in the EU is shellfish. Mussels and oysters are the most popular shellfish. Marine fish such as salmon, sea bream and sea bass represent about 27% of our fish farm produce whilst freshwater fish such as trout and carp account for 23% of fish farmed in the EU. The species farmed in the EU are very diverse and include clams, scallops, lobsters, and sturgeon (caviar). Algae production is a developing sector.
