- Avoid direct translation. It is a specific species name, not a general word for a fish (рыба). Closest generic term might be 'корюшка' (smelt), but it is a different genus/family.
Common Mistakes
- Spelling as two words: 'jack smelt' is common but the standard spelling is one word. Confusing it with the unrelated 'jackfish' or 'jack mackerel'.
