Other notable comments and clues:

• The most distinguishing feature of the juvenile broad whitefish is its mouth forms a blunt snout that is sheep-like.
• Can be very easily mistaken or confused with juvenile lake whitefish.
• Broad whitefish <100mm are very hard to distinguish from lake whitefish. They tend to have more of a girth behind their head/before the dorsal fin (think: wider and deeper cross-section in front of the dorsal fin).
