In vitro storage of pikeperch (Sander lucioperca) eggs
Original language description
The possibility of egg storage after stripping was examined in pikeperch (Sander lucioperca). The storage temperature was adjusted to 4 degrees C, as the cold storage temperature, and to 15 degrees C, as the natural spawning temperature of pikeperch. Batches of 2g egg aliquots from four females were fertilized at 0, 12, 24, and 48h post stripping (HPS). The highest fertilization and hatching rates were obtained immediately after the stripping of the eggs. Thereafter, the values decreased significantly (P<0.05); fertilization rates dropped to 5% at 48 HPS at the storage temperature of 4 degrees C and to 10% at 24 HPS at 15 degrees C. In addition, with elapsing time after ovulation, the embryo mortality and larval malformation rates increased significantly. The embryo mortalities increased from 35% at 0 HPS to 100% at 24 HPS at 4 degrees C and at 12 HPS at 15 degrees C. The larval malformation rates also increased from 36% at 0 HPS to 71% at 12 HPS at the storage temperature of 4 degrees C. Pikeperch eggs, therefore, should be immediately fertilized after stripping to obtain the highest egg fertilization and hatching rates, as well as the lowest embryo mortality and larval malformation rates.
