Black rockfish has been cultivated since the dawn of the Korean aquaculture industry and is regarded as an important species as it has accounted for 41% of the cultured fish production in Korea for the past ten years. Moreover. about 70% of all fish farmers cultivate black rockfish as the main fish stock in their aquaculture business. The volume of cultured black rockfish is more than 20,000 tons every year. The objective of this paper is to clarify the structural change of the Korean aquaculture industry by referring to a change in the volume of production of cultured black rockfish across different production areas. Concretely, six major production areas in Korea, including Tongyong and Yeosu, have been examined as regards their trends of production of black rockfish. Considering production environment and management realities, each aquaculture production area has its own density of fish releasing and period of culture. Six major production areas can be divided into three types. The first type is the production area with high density and short-term culture. The second type is the production area with low density and long-term culture, and the last is the type without stable density culture and term culture.
This paper analyzes how these three different production types have changed the volume of cultured fish production in response to newly-appeared consumption trend in their major markets. The changing processes of six major production areas have been discussed referring to production environment, business management, profitability of aquaculture, and consumption trends.
