Ovulatory rhythms and over‐ripening of eggs in cultivated turbot, Scophthalmus maximus L.
The aim of this study was to investigate ageing of ovulated eggs retained in the ovarian lumen of captive turbot, Scophthalmus maximus L., prior to handstripping. The ovulation times of egg‐batches were determined by catheterization, handstripping and plotting the percentage fertilizations and hatch...
