The effect of prepared activating liquid on the survivability of ide Leuciscus idus (L.) embryos.

A preliminary examination was carried out into the effect that various activating liquids have on the survivability of ide Leuciscus idus (L.) embryos. It was found to be similar (54–59%) in four study groups; the embryo survivability was found to have decreased (44%) only in the group where non-sterilised tap water was used for gamete activation. A negative correlation was found between water conductivity, salinity and sperm motility. A positive correlation was found between water conductivity, salinity and embryo survivability. A negative correlation between the sperm motility and the survivability of ide embryos at the eyed-egg stage shows that the fertilisation result is more affected by the duration of sperm movement than by the percentage of motile sperm.
