Marine aquaculture

NACE v2.0 Code: A03.21

About marine aquaculture

NACE code 03.21 covers the industry of marine aquaculture, which plays a vital role in the global food supply and the broader economy. This industry focuses on the farming of various aquatic organisms, such as fish, crustaceans, and mollusks, in marine environments. As the demand for seafood continues to rise, marine aquaculture has become an increasingly important source of sustainable and reliable food production.

Production process

The key production techniques used in marine aquaculture involve the controlled breeding, rearing, and harvesting of aquatic species. This typically includes the use of specialized facilities, such as offshore cages, onshore tanks, or coastal ponds, where the organisms are raised in a controlled environment. The production process often involves the management of water quality, feeding, and disease control to ensure the health and growth of the aquatic species.

Production inputs

The main inputs required for the marine aquaculture industry include a suitable marine environment, such as coastal waters or offshore areas, as well as specialized equipment and infrastructure, such as cages, nets, and pumping systems. Additionally, the industry relies on various inputs, such as fish feed, hatchery-produced juveniles, and skilled labor to operate the production facilities.

Production outputs

The primary outputs of the marine aquaculture industry are the harvested aquatic organisms, which can include a variety of finfish, crustaceans, and mollusks. These products are then typically sold to 10.20 Food processing and preserving of fish, crustaceans and mollusks, 46.38 Wholesale of other food, including fish, crustaceans and mollusks, or 47.23 Retail sale of fish, crustaceans and mollusks in specialized stores for further processing, distribution, and sale to consumers.
