Development, and effect of water temperature on development rate, of pikeperch Sander lucioperca embryos

Popis výsledku v původním jazyce

Knowledge of embryo development is essential to the application of reproductive biotechnology in aquaculture, including for pikeperch Sander lucioperca. We describe pikeperch embryo development and demonstrated effects of temperature on the duration of embryogenesis. Developmental stages in embryos incubated at 15 degrees C were identified as zygote, 0-1.5 h post-fertilization (hpf); cleavage, 2.5-7.5 hpf; blastula, 9-18.75 hpf; gastrula, 21-39, hpf; segmentation, 45-105 hpf; and hatching, 125-197 hpf. Additional groups of eggs were fertilized and incubated at 10, 15, 20, and 25 degrees C to document stages of development, development rate, and survival. The optimal fertilization and incubation temperature was shown to be 15 degrees C, with the highest fertilization, survival, and hatching rates. Embryo development was slower at 10 degrees C, with 45% of fertilized embryos surviving to hatching. Development was accelerated at 20 degrees C, and resulted in a 56% survival rate of fertilized embryos. At 25 degrees C, embryos did not develop to the blastula stage. Pikeperch could be a valuable percid model for research in which flexible incubation temperatures is required.
