There are 36 shrimp farms in Ganghwa county (696 farms across the country), and six out of the 36 farms culture shrimp in an environmentally responsible manner. 

In case of whiteleg shrimp farming, the yield was 9,504 tons in 2022, which was down to 7,047 tons (approximately 26% decline) in 2023 due to the occurrence of Acute Hepatopancreatic Necrosis Disease (AHPND). 2024 also ended up 7,766 tons without the yield being fully recovered.

NIFS had developed eco-friendly aquaculture techniques since 2003 and disseminated them to local governments and private aquaculture farms through training for start-ups. It also has been developing shrimp resistant to bacterial diseases since 2024 and the development of customized formulated feed is in the process to reduce feed costs and improve aquaculture productivity.
