Goyang Koi Farm – Archive
The Korean authorities have chosen, for now, not to support koi under their export policy. Perhaps that is understandable.
Given the current state of the world—with environmental and economic problems, and wars being fought—the koi hobby may even feel like a fetish for the rich. Even so, Hugo J. Smal and Kim Young Soo want all the knowledge collected under the Goyang Koi banner to remain available in this archive,
so enthusiasts can continue to use it.
Note: active koi operations have ceased; this page functions as a living archive of materials previously published under Goyang Koi.
About this archive
This archive preserves practical koi knowledge and context that were once part of the Goyang Koi project. Our aim is continuity: to keep guidance available for keepers who value careful husbandry, water management, and clear documentation.
Over the years, the Farm gathered a wealth of practical insights — from feeding logs to water testing notes and from breeding experiments to cultural reflections. As a reference for Korean koi keepers, it covers koi breeding in Korea, koi care and water quality, and core koi varieties such as Gosanke (Kohaku, Sanke, Showa). The archive also reflects the exchange between East and West, where Bidan Ing-eo (the Korean name for Nishikigoi) connects hobbyists and traditions.
Where relevant, we link to Mantifang for broader cultural context. If you are looking for the landscape project that succeeded the former theme park, visit the Baedagol page on Mantifang.

Temporary pause on koi exports — healing park in development
International koi exports are currently on hold. Meanwhile, we are laying the foundations for a nature-driven healing park in Goyang that blends koi culture, art, and quiet craftsmanship. For updates or collaboration, feel free to get in touch.
