Aquaculture Products

1. Overview

Aquaculture refers to the controlled cultivation of fish, crustaceans, mollusks, and aquatic plants under managed environmental conditions (FAO,2024a). Today, it plays a strategic role in addressing overfishing, ensuring food security, and supporting the goals of the blue economy. According to FAO (2024b), aquaculture production (51%) surpassed capture fisheries (49%) for the first time in 2022.

2. Aquaculture in Türkiye

Aquaculture production in Türkiye has grown rapidly in recent years.

As of 2023, total fishery production reached 1,007,921 tons, of which 55% came from aquaculture and 45% from capture fisheries (TURKSTAT,2024).

Most produced species in Türkiye:

  • Freshwater species: Rainbow trout, Mirror carp, Tilapia
  • Marine species: Gilthead seabream, European seabass, Meagre (Granyöz), Bluefin tuna, Mediterranean mussel
  • Main production regions: Aegean, Black Sea and Mediterranean Regions

These species are farmed using various systems such as ponds, raceways, floating cages, recirculating aquaculture systems (RAS), and longline mussel farms, depending on local water conditions and technological capacity.

3. Global Aquaculture

Asia

  • China is the world’s largest aquaculture producer, leading in carp, catfish, tilapia, and seaweed farming.
  • Indonesia, Japan, Korea, and the Philippines specialize in red, brown, and green algae production.
  • India also maintains strong aquaculture activity, particularly for shrimp (Penaeus monodon) and inland fish farming.

Europe

  • Norway and Scotland dominate salmon farming, while Greece and Türkiye are leading producers of sea bream and sea bass in the Mediterranean.
  • France and Spain are well-known for mussel, oyster, and flatfish cultivation.

America & Oceania

  • Chile, Canada, Australia, and New Zealand are among the top global producers of salmon and trout.
  • In the United States, NOAA (National Oceanic and Atmospheric Administration) supports sustainable aquaculture research and innovation through grants focused on shellfish farming, new species development, and alternative feed research.

4. Key Aquaculture Species

The main aquatic species produced under saltwater and freshwater conditions are summarized in Table 1 (Laird, 2001).

5. Sustainability and Social Impact

  • Aquaculture aligns with FAO’s “Blue Transformation” vision, promoting environmental, economic, and social sustainability.
  • Shellfish such as mussels and oysters help reduce nitrogen and phosphorus pollution through natural filtration.
  • Women, youth, and small-scale producers receive technical and training support through FAO Aquaculture Demonstration Centers (ADC) located in Egypt, Romania, and Türkiye.
  • Technological innovations such as water quality monitoring sensors, drones, and automated feeding systems are enhancing productivity and reducing environmental impacts.
