Farmed oysters, live, fresh or chilled

cpc code 04422 covers the production and trade of farmed oysters, a highly valuable and nutritious seafood product. Oyster farming is a significant industry within the broader aquaculture sector, providing a sustainable source of protein and contributing to global food security. As a popular delicacy, farmed oysters are in high demand worldwide, making this code an important component of international trade and the global food supply chain.

Farmed oysters are typically cultivated using specialized techniques such as bottom culture, off-bottom culture, and suspended culture. In bottom culture, oysters are grown directly on the seafloor, while off-bottom culture involves raising them on racks or trays. Suspended culture, also known as long-line or hanging culture, involves growing oysters in mesh bags or cages suspended from floating structures. These production methods allow for efficient and controlled growth, ensuring a consistent supply of high-quality oysters.

The production of farmed oysters requires several key inputs, including clean, nutrient-rich seawater, specialized equipment such as oyster cages or trays, and skilled labor for tasks like seeding, monitoring, and harvesting. Hatcheries also play a crucial role, providing a reliable source of oyster larvae or 'spat' to stock the farms. Additionally, feed supplements and water treatment systems may be necessary to maintain optimal growing conditions.

Farmed oysters produced under cpc code 04422 are primarily destined for the food service industry, where they are consumed fresh or used in a variety of culinary preparations. The output of this industry may also be further processed, such as shucking or canning, before being distributed to 04423 Oysters, shucked, fresh or chilled or 16312 Prepared or preserved oysters industries.
