How to identify Arctic char
- Dark back with pale spots; breeding adults can be orange-red below.
- Streamlined, with light spots that stand out on darker skin.

Field note: color, size, and markings can change with age, sex, season, depth, and lighting. Use several traits together.

A conservation lens
Healthy lake populations depend on suitable temperature and oxygen, clean spawning areas, and balanced harvest and food webs.
This habitat lens is not a current population-status assessment. Status can differ among regions and change as new assessments are published; follow the reference links and local fisheries or wildlife agencies for current decisions.
