Testing for the development of low phosphorous content feedstuff
2001 - 2002
In the carp aquaculture in Kasumigaura and Kitaura, it is obliged to use the "improved feedstuff" having a crude protein content not exceeding 36% to reduce the environmental nitrogen burden. Furthermore, in order to reduce the environmental phosphorous burden, a "low phosphorous content feedstuff" was developed as a result of consigning to Tokyo University of Fisheries. This kind of feedstuff was manufactured by consignment and used for a verification test netting preserves of practical scale. The test revealed that the feeding result was substantially equal to those with the "improved feedstuff", the remaining issue being cost reduction.
