KREIDL-KOI is a Czech specialist in Japanese koi carp, pond fish, and the design and construction of ponds and pools. Founded by Jan Kreidl, the business grew from his long-standing interest in koi into a dedicated breeding and sales operation. Its fish come from leading Czech breeders and first-rate Japanese farms, with an emphasis on good health and quality. Customers can browse the koi catalogue and choose from original Japanese koi, as well as other pond fish and sturgeon.

KREIDL-KOI also builds garden ponds and pools and supplies related accessories, serving customers looking to create or equip aquatic spaces. The founder’s own facilities include an indoor 13-cubic-metre pool for overwintering koi and four additional breeding tanks, providing capacity to keep fish in approximately 90 cubic metres of water. This hands-on experience informs the company’s focus on koi care and pond keeping. Based in Zálší near Veselí nad Lužnicí, KREIDL-KOI invites customers to share its enthusiasm for Japanese carp and offers information about its products and services through its website.
