摘要: The present study investigated the biochemical composition and quality of turbot (Scophthalmus maximus) eggs throughout the reproductive season. Results showed that the fertilization, hatching and egg floating rates were variable throughout the reproductive season, with the highest values recorded during the mid-season. Meanwhile, positive correlations were found between fertilization, hatching rate and floating rate. The composition of turbot eggs, including total lipid, protein, carbohydrate, moisture and dry weight showed no significant differences during the reproductive season. Furthermore, no correlations were found between egg compositions and viability parameters (VPs), including fertilization and hatching rates as well as larval deformity rate. However, egg diameter varied and correlated with fertilization, hatching and egg floating rates. The fatty acid in eggs at mid-season had significantly higher levels of C14:0, C16:0, C16:1n-7, C18:0, C18:1, C20:4n-6, C20:5n-3 and C22:6n-3. Moreover, significant relationships were found between fatty acids and VPs. Eggs of the middle season had significantly higher concentration of isoleucine, leucine, lysine, methionine, valine, alanine, aspartate, glutamate and serine, whereas no significant relationships were found between amino acids and VPs. These observations suggest that the biochemical profile of eggs may be useful in evaluating egg quality and improving broodstock management for turbot.
