Their unique appearance is the result of dedicated breeding efforts focusing on coloration and scale development. Due to their scaleless bodies, these koi require specific water conditions to thrive, necessitating parasite prevention and sun protection. The market value of Shusui Koi varies depending on factors such as age, coloration, scale pattern, genetic quality, and the reputation of the breeder. Proper care involves maintaining optimal water temperature and providing a nutritious diet to support their vibrant colors and overall health. As we delve deeper, you will learn more about the breeding techniques used and the essential care requirements for Shusui Koi.

Shusui Koi Background

Originating from selective breeding practices developed in China and Japan around the 4th century, Shusui Koi are a unique and captivating variety within the koi family, descending from the common carp. The historical significance of Shusui Koi lies in their development as one of the first Doitsu varieties, known for their distinctive lack of scales. Early koi enthusiasts focused on specific traits like coloration and scale patterning, leading to the creation of the Shusui Koi with its unique appearance and revered status in koi culture. Understanding the historical context of Shusui Koi breeding offers valuable insights into the meticulous efforts required to establish such a distinguished lineage.

Key Characteristics

Shusui Koi stand out with their distinctive blue-grey patterns and 2 to 4 rows of blue scales running along their back. These unique scales, a result of selective breeding, highlight the genetic traits that make Shusui Koi unique among other koi varieties. Their streamlined body structure enables graceful movement in water. The scale development in Shusui Koi is notable, with scales concentrated along the dorsal line, giving the rest of the body a smooth, scaleless appearance. This feature, inherited from Doitsu lineage, underscores the significance of careful breeding practices. Understanding these characteristics is key for enthusiasts seeking to appreciate the beauty and complexity of Shusui Koi.

Proper Care

To ensure Shusui Koi are healthy and vibrant, it's crucial to pay close attention to water quality, temperature, and their diet. These fish, known for their scale-less bodies, require top-notch water conditions maintained through proper aeration and filtration to prevent harmful ammonia and nitrate buildup. Parasite prevention is essential for Shusui Koi, as they are prone to infections. Their vulnerability to sunburn due to the lack of scales necessitates shaded areas or pond covers to protect them from excessive sun exposure. Regular checks and a well-balanced diet rich in essential nutrients are key to their well-being, allowing them to showcase their beautiful colors and graceful movements. By addressing these specific needs, Shusui Koi can thrive and remain healthy.

Pricing and Breeding

Shusui Koi pricing and breeding are influenced by several key factors that impact their market value and genetic quality. Factors such as age, coloration, scale pattern, genetic quality, and breeder reputation all play a crucial role in determining the price of these beautiful fish. Younger Shusui Koi are generally more affordable, while those with vibrant colors and unique scale patterns command higher prices. Additionally, the genetic quality of the fish, as well as the reputation of the breeder, can significantly affect the market value of Shusui Koi.

When it comes to breeding Shusui Koi, breeders carefully select parent fish to ensure desirable traits are passed down while minimizing potential genetic issues. By employing meticulous breeding practices, reputable breeders can enhance the overall quality of Shusui Koi, ultimately increasing their market value. It is important to consider these factors when pricing and breeding Shusui Koi to maintain their genetic integrity and desirability in the market.

Coloration and Diet

Understanding how diet and coloration are intertwined is crucial for maintaining the vibrant appearance of Shusui Koi. The water temperature significantly affects the pigmentation of these fish, with optimal temperatures ranging from 68-75°F enhancing color vibrancy. Fluctuations in temperature can result in dullness or stress-related color fading. Feeding habits also play a vital role in coloration, with a well-rounded diet supplemented with color-enhancers like spirulina and carotenoids helping to preserve the vivid blues, reds, and yellows that define Shusui Koi. Consistent feeding schedules, avoiding overfeeding, are essential for steady growth and color retention. Monitoring both water temperature and diet is key to ensuring the health and striking beauty of Shusui Koi, showcasing their true magnificence and heritage.


The Shusui Koi is a masterpiece of breeding artistry, reflecting centuries of expertise and cultural significance.
