JEJU, South Korea, Feb. 17 (Korea Bizwire) — Scientists in Jeju are making strides in developing artificial breeding technology for mackerel, aiming to bolster sustainable aquaculture practices and reduce dependence on wild-caught juveniles.
The Jeju Marine and Fisheries Research Institute announced on Monday that mackerel hatched through artificial insemination last August have grown to approximately 110 grams in weight and 25 centimeters in length.
The researchers anticipate that with an additional five to six months of cultivation, the fish will reach the commercial weight range of 300 to 500 grams by the second half of 2025.
The market price for a 300-gram live mackerel is currently set at KRW 15,000 ($10.35), highlighting the economic potential of this aquaculture method.

While mackerel farming has been practiced both offshore and on land, it has traditionally relied on capturing wild juveniles, leading to concerns over supply shortages.
The new artificial breeding approach aims to address this issue by ensuring a stable supply of juvenile fish for aquaculture operations.
The research institute is conducting pilot trials with one offshore cage farm and two land-based farms to assess the economic viability of artificially bred mackerel.
Additionally, efforts are underway to develop a standardized production manual for artificial mackerel breeding and to support the broader aquatic seed industry.
If successful, this initiative could pave the way for a more sustainable and commercially viable mackerel farming industry in South Korea.
