Tagged s ardine S. melanostictus was held in a 3m3 tank from December 22, 1981 to February 15, 1982 for the development of tagging technique. Average mortality of tagged fish was 11.4% and it occurred mainly in the early period of experiment. These fishes which died in early stage showed much scraping of the scale, and it was thought to be the cause fo death.
Serum glucose suddenly increased just after tagging, but gradually fell to the level of intact fish. Serum chloride of tagged one was higher than intact fish throughout experiment, while the haematocrit value was lower than the intact one. The serum protein and condition factor of tagged fish were lower than the control.
