This study about morphological observation of pre- or post ovulated eggs obtained from artificially maturated female eels. Female eels were divided with two groups as wild eels from nature and feminized eels from farm. Artificial maturation had been conducted with the established methods in this laboratory, and then maturate eggs sampled at fixed 3 times and these were observed with stereomicroscope. Rate of increased body weight (RIW) were measured with 2 times. Egg diameters and development of oil droplets are determined for standardization of egg maturation degree, and the transparency of egg cytoplasm and the homogeneous degrees of egg size were referred to determine of egg quality. Rate of increased body weight (RIW) were good in range about 10 % at final salmon pituitary extracts (SPE) injection time and in range about 20 % at 17α, 20β-dihydroxy-4-pregnen-3-one (DHP) injection time. Good matured egg for fertilization had 900-1000 ㎛ diameter, and they had about 50 oil droplets in size about 100 ㎛ diameter. There were not predominant differences at egg size and oil droplet development between wild female and feminized eels.
