Selecting Karashigoi Koi with Jumbo Potential from Marudo | Part 01 | Raising Japanese Koi

Welcome to the first episode in our Raising Japanese Koi series featuring Karashigoi Koi from Marudo Koi Farm—one of Japan’s most respected breeders of jumbo koi. In this video, Ricky Stoddart begins the grow-out journey by introducing the first batch of young Karashigoi with serious potential.

These Tosai are already showing impressive growth, some reaching 26cm despite being just 12cm on arrival. With genetics rooted in Marudo’s powerhouse bloodline—known for producing koi over 85cm—this video sets the stage for what could be one of the most exciting grow-outs of the year.

Follow the early-stage development, learn what Ricky looks for in bone structure and body line, and get a glimpse of the standout fish that could go on to become absolute monsters.

This is just the beginning. Don’t forget to subscribe and follow the entire journey as we document the growth and transformation of these incredible Karashigoi Koi.
