摘要	Chromosome manipulation, such as gynogenetic induction, is an effective method in fish to quickly obtain high inbreeding coefficient which is useful for genetic breeding. Based on different induction protocols, there are two kinds of gynogenesis, meio-gynogenesis (MEG) and mito-gynogenesis (MIG), which retain high level of heterozygosity or theoretically homozygous. Until now, little is known about the growth and morphological differences between these two gynogenesis. The present study analyzed the growth and morphological characteristics of the MEG and MIG stocks in the olive flounder Paralichthys olivaceus, an important maricultured fish. The results showed that the growth trends of both the MEG and MIG stocks at 3, 6, 9, 12, 18, and 24 months post hatching (mph) were similar to the control stock, and the inflection point of growth curve was at 12 mph. They all presented fast growth from 12 to 18 mph (P < 0.05). Overall, the MEG fish showed a similar growth with the control diploids, while the MIG fish had a better growth performance to some extent although their growth was quite different. The difference of the specific growth rate in body weight (SGR(w)) among different stocks indicated their allometric growth. In terms of the morphological characteristics, different stocks showed different shapes. Compared with the control stock, the body shape of the MEG stock is thinner and longer, while that of the MIG stock is mellower. The frame data indicated that the cumulative contributive proportions of two main principal components extracted with principal component analysis were 79.75% and 78.88% in the MIG and MEG stocks at 12 mph, respectively. And the shape dispersion of the MIG stock was higher. Based on correlation and regression analyses of the morphological parameters and body weight, the morphological data were also shown to be correlated with the weight gain, and the key characteristic values related to the body weight among the flounder stocks concentrated mainly along the direction of head-tail axis. The results revealed that both the MEG and MIG ones have normal or even some advantages on their growth characteristics, which could be used for the flounder breeding.
