内容記述 | Field experiments focusing on the variation in dissolved oxygen were carried out from July to September, 2000, in a small-scale culture field to elucidate the cause of the mass death which often took place there. These experiments revealed that the concentration of the dissolved oxygen(DO) widely changed with the diurnal or shorter period though it also changed over the period of several days. Currents affecting on the environmental variations were rather curious. The M2 current was very small and the components with the periods of 17.1 hours and 21.2 hours(the inertia period)were clearly recognized although M2 and S2 were fairly dominant regarding the tides. The mortality rate of each fish in the culture field varied day by day. It has been recognized from examination that the high mortality rate of yellowtails that was major component well corresponded to the deficiency of DO, which occurred with the period of several days. We couldn't elucidate the cause of the DO variation with this period of several days though it was recognized that the short-term variation of one day or less was induced by the current changes. | |||||
