Table 2 Spermatozoa activity index (SAI) of far eastern catfish, Silurus asotus dilution after 1 hour and 24 hours cool storage in two diluents

Diluent	SAI^*
Diluent	Activation (1 hour)	Storage (24 hours)
Alsever's solution	1.6±0.18^a	0.5±0.07^b
0.3 M glucose	1.4±0.22^a	0.3±0.09^b

^*SAI: (Score × % motile sperm)/100 (After Strüssmann et al., 1994). The temperature of storage is 0℃. Values are means±SD. Values in same row having the different superscripts are significantly different (n = 100, P<0.05). Experiments are triplicate.
