In the picturesque island of Jeju, South Korea, scientists are making waves in the aquaculture industry with their groundbreaking work on artificial breeding technology for mackerel. The Jeju Marine and Fisheries Research Institute recently announced that mackerel hatched through artificial insemination last August have shown remarkable growth, reaching approximately 110 grams in weight and 25 centimeters in length. This significant milestone brings the fish closer to the commercial weight range of 300 to 500 grams, which is expected to be achieved by the second half of 2025. The market price for a 300-gram live mackerel is currently set at KRW 15,000 ($10.35), underscoring the economic potential of this innovative aquaculture method.
Traditionally, mackerel farming has relied heavily on capturing wild juveniles, a practice that has raised concerns about supply shortages and sustainability. The new artificial breeding approach developed by the research institute aims to address these issues by providing a stable supply of juvenile fish for aquaculture operations. This not only ensures a consistent source of fish for farmers but also reduces the pressure on wild mackerel populations, promoting more sustainable fishing practices.
The research institute is currently conducting pilot trials with one offshore cage farm and two land-based farms to evaluate the economic viability of artificially bred mackerel. These trials are crucial in determining the feasibility of large-scale production and market integration. Additionally, the institute is working on developing a standardized production manual for artificial mackerel breeding, which will support the broader aquatic seed industry. This manual will serve as a valuable resource for farmers and researchers, providing guidelines and best practices for artificial breeding and cultivation.
The implications of this research are far-reaching. If successful, this initiative could revolutionize the mackerel farming industry in South Korea, making it more sustainable and commercially viable. By ensuring a steady supply of juvenile fish, farmers can focus on optimizing their cultivation techniques and expanding their operations without the uncertainty of relying on wild-caught juveniles. This, in turn, could lead to increased production, job creation, and economic growth in the aquaculture sector. Moreover, the development of a standardized production manual will facilitate the adoption of this technology by other aquaculture operations, further enhancing the industry’s sustainability and resilience.
