The aim of the study was to investigate the stress response caused by air exposure, simulating live transport, in small abalone, Haliotis diversicolor. Five hemolymphatic parameters, including total hemocyte count, concentrations of oxygenated hemocyanin, glucose and protein, and osmolarity in hemolymph, for 2, 4 and 6 h air-exposed treatments were examined, and the survival rates in 7 d after the treatments were traced. Most hemolymphatic parameters, except glucose concentration, showed no significant differences among the control (0-h) and time (2-, 4- and 6-h) treatment groups. Air exposure treatments stimulated hyperglycemia. However, the hyperglycemia did not seem to result in serious impairment in the transport of abalone. The survival rates 7 days after air exposure were still high, more than 15% on average.
