Facts

  • In N-Am 3 subspecies: S. a. erythrinus, S. a. oquassa (sunapee or blueback trout), S. a. taranetzi (taranets or dwarf Arctic char); In Eurasia:S. a. alpinus (ref: Wiki)
  • Char does not die after spawning like Pacific salmon and often spawn several times throughout their lives, typically every second or third year. (ref: Wiki)
  • Young char emerge from the gravel in spring and stay in the river from 5 to 7 months or until they are about 68 in (1520 cm) in length. (ref: Wiki)
  • Best culturing temp 7.5-12.5 C. (ref: YaniHisa2002)

Discussion

  • weight 0 was given to Wh, because value does not seem realistic
