Abstract
    After the treatment with Ovopel (alone or with the pituitary) the percentage of spawning females was higher yet the weight of eggs in spite of their very good quality (percentage of fertilization and live embryos above 90) was statistically lower than that obtained after hypophysation. No effect of the group or provenance on the quality of eggs or of the provenance on their weight was recorded. The ovulation time was 7-8 h both after two Ovopel injections and after hypophysation. In the group treated with pituitary and Ovopel the ovulation occurred four hours later.
