Associated characteristics

Species Development state Trait Primary Data Secondary Data
Acipenser ruthenus Egg Egg adhesiveness Yes "fertilized sturgeon eggs become sticky within a few minutes after coming in contact with water" Adhesive
Acipenser ruthenus Egg Temperature for incubation 7-15°C; 10h "We found that sterlet eggs do not need to be fertilized immediately after collection. Reasonably good quality was retained for several hours if temperature conditions are fairly cool and stable. Eggs retained good quality when stored at 7°C and 11°C for up to 10 h with 54.1 ± 2.9 to 69.9 ± 7.9% hatching success, but egg quality was significantly reduced after 5‐h storage at 19°C (p < 0.01) and 7.5‐h storage at 15°C (p < 0.05) compared to cooler temperatures. Uniform temperatures between 7°C and 11°C can be considered as appropriate for storage of eggs in ovarian fluid for up to 10 h" 54.1 °C
Acipenser ruthenus Egg Degree-days for incubation 16°C/5-6 days (eggs incubation) "5‐ to 6‐day post‐fertilization; water temperature during incubation was 16°C" 5.5 °C * day
