Abstract: In Japan, the Japanese scallop aquaculture industry has started in Lake Saroma, Hokkaido. Recently, the scallop in the lake are produced from 4,000 tons to 9,000 tons in year by hanging culture. However, mass die-offs of cultured scallops have been frequently observed in the lake. For instance, hte mortality rate in 2007 and 2008 reached about 10% or more of the amount of aquaculture. Although these die-offs might be due to abrupt changes in the aquaculture environment, the relationship between environmental stress and die-off in scallops has yet to be clarified. Our previous results suggest that arginine phosphate concentration(ArgP) in the adductor muscle can be a good predictor of scallop die-off. This study aimed to evaluate scallop die-off on the aquaculture site by using ArgP. We investigated the relationship between the environmental changes such as water temperature, salinity, dissolved oxygen concentration, and water flow in the lake and ArgP in the adductor muscle. As a result, annual average of ArgP showed 14.6 ± 2.6 mol/g in the year characterized with less environmental change and low mortality rate. Therefore, the value of AreP would become one of the indicator to evaluate the changes in the aquaculture environment.
