| Popis: | Sockeye salmon Oncorhynchus nerka sperm maintained high fertility for 10 s after being exposed to water but fertility dropped sharply after that. Eggs also showed limited longevity after being immersed in water, with a large drop in fertility occurring after 20 s of exposure to water. The association between eggs and sperm occurs very rapidly. 80% fertilization success was achieved with 5 s of sperm-egg mixing and c. 25% was achieved with |
