| Reproduction Preferences Additional Information | Reproduction continues throughout the year with peak reproductive activity in the warm summer months in the UK. In France, life span varies from 48 to 408 days according to the water temperature when born (Janssen et al., 1979). Those born in the winter develop 4 to 5 times slower than those born in the summer. Egg incubation time also increases with a reduction in water temperature from 7 days in summer to 50 days in winter. | ||||||||||||||
