Embryonic Development and Fry of the Kyûriuo, Osmerus eperlanus mordax (Mitchill).
摘要
Smelt eggs were artificially fertilized and the embryonic development was observed in water temperature regulated at 11±0.5°C during the incubation. The eggs were demersal and adhesive, and, after water absorption, measured from 1.28 to 1.51 mm in diameter. 453 hours (19 days) after fertilization, hatching occurred and the total length of the newly hatched fry ranged from 7.21 to 7.80 mm.
