摘要

We studied to find out the effect of water temperature on the egg development of pearl oyster, Pinctada fucata martensii and Pacific oyster, Crassostrea gigas. The optimum water temperatures for egg development were 20 approx 25 deg C in P. fucata martensii and 15 approx 25 deg C in C. gigas. The required time from fertilization to D-shaped larva was 41.7 hours at 20 deg C and 27.5 hours at 25 deg C in P. fucata martensii, and 35.3 hours at 15 deg C, 26.3 hours at 20 deg C and 17.6 hours at 25 deg C in C. gigas, respectively. The relationships between the water temperature (WT: deg C) and the required time (h: hour) from fertilization to each developmental stage were given as follows; P. fucata martensii; Up to 8-cell 1/h=0.0463WT-0.6945 (r~2=0.9702) Up to morula 1/h=0.0196WT-0.2184 (r~2=0.8118) Up to trochophore l/h= 0.0076WT-0.0802 (r~2=0.8756) Up to D-shaped larva 1/h=0.0031WT-0.0380 (r~2=0.9075) C. gigas; Up to 8-cell 1/h=O.0210WT-0.1123 (r~2=0.9862) Up to morula 1/h=0.0143WT-0.1077 (r~2=0.9833) Up to trochophore 1/h =0.0052WT-0.0218 (r~2=0.9857) Ut) to D-shaped larva 1/h=0.0029WT-0.0170 (r~2=0.9689) Biological minimum temperature for egg development of P. ucata martensii and (7. gigas was calculated as 12.3 deg C and 5.7 deg C, respectively.
