Living Conditions
🐟 Habitat preferences
- Arctic graylings inhabit clear, cold rivers, streams, and lakes, thriving in well-oxygenated waters
- They are often found in montane and piedmont streams, where the current is strong and the water is cool
- This species prefers environments with rocky substrates and minimal pollution
- Their diet primarily consists of surface insects, but they also consume fish eggs, small fish, and crustaceans
♻️ Life cycle and mating behavior
- Spawning occurs in the spring, with adults moving into tributaries and males establishing territories
- Males court females by displaying their dorsal fins and creating slight depressions in the substrate
- Eggs are fertilized in these depressions without the construction of a proper nest
- After spawning, adults establish territories in upstream pools and most move downstream by mid-September
