As you can see, Newbie here:
Seems like the ultimate environment to gain length and girth with Koi are large mud ponds like the one's Professional breeders in Japan use.
I have a few questions about this scenario-
You start with a Kohaku tosai and grow it in a mud pond for 5 seasons, now instead of the mud pond you grew the same fish in a professionally constructed 15,000 gallon cement pond.
Of course there are a million variables here that make it difficult. Let's assume the mud pond is managed by a top Japanese professional and the cement pond is managed by one of the top American professionals.
-Would the mud pond or cement pond produce better results-(i'm guessing mud pond)
-Could the cement pond fish ever catch up to the mud pond fish-in length and width? Assuming same environment after years in the mud or cement pond (i'm guessing no)
-Is this statement true-If you want the largest possible fish for its type/variety, its probably spent time in a mud pond.
-Growing in smaller sized cement ponds, what size in relationship to the same mud pond fish could you get? Say for example 70% length, but only 60% girth?
-Do you know what fish in mud ponds eat? What percentage is natural occurring food in pond and what food is given to the fish?
-Do you know what type of maintenance is done to a mud pond during the growing season?
Really appreciate it!
