[quote=MikeM;80149]Eugene: I believe Momotaro is doing 10% or so daily inflow of fresh water. I hope none of it is from a river. Bio-security concerns would negative use of surface waters inhabited by carp (or any fish IMO) without pre-treatment to drinking water standards or similar. I understand that Brett uses a surface reservoir as source water in his operations, but I have the impression that his bio-security procedures are very stringent. A constant in-flow of fresh water of proper condition is ideal. As DickB points out, however, what the Japanese sometimes call "raw water" may maintain fish health, but is considered negative for the best development. The term "mellow water" is a subject on which JR does an excellent job of waxing eloquently.

I do not think that he would be getting water from the river now I was going by an old Rinko article . There are so many variables such as water temperatures size of pond stocking rates and feeding rates . If for example the fish were mature females that spent 4 months in a mud pond they would be fed little . In our small ponds meaning 10000 gal and fish all year round the Baki would be just good added filtration .I hope to go there next year so will be able to see for myself .
