There are very diverse production methods for EU aquaculture species, some of the main ones are the following (STECF Aquaculture economic data table, 2023):
- Enclosures, pens, recirculation systems and tanks for salmon;
- Tanks and raceways, recirculation systems and ponds for trout;
- Pens, tanks, ponds, recirculation systems for sea bass and sea bream;
- Rafts, polyculture, logline for mussels;
- Ponds, tanks, raceways, gages, polyculture for carp;
- On-bottom, longline, rafts and polyculture for oyster;
- Ponds, raceways, tanks for crustaceans;
- On bottom, tanks and raceways, pens, recirculation systems, polyculture, rafts, longline, tanks for seaweed;
- Open or closed-system bioreactors for microalgae.
In addition, during the early growth stages, most fish species and seaweeds need to be in a hatchery and a nursery. Seeds of molluscs are produced in hatcheries or collected from the wild.
