Physical Identification: How to Tell Cod and Haddock Apart
Cod vs Haddock Identification Features
Distinguishing between these related species becomes easier once you know their key physical characteristics.
Cod Identification:
- Speckled gray-brown or green-brown coloration
- White or cream-colored lateral line
- Rounded, uniform dorsal fins
- Thick, chunky body shape
- Can grow over 40 inches and exceed 25 pounds
- Large, muscular fillets
Haddock Identification:
- Dark gray to nearly black upper body
- Distinctive black lateral line
- Black oval blotch above pectoral fin (called "Devil's thumbprint")
- Long, pointed front dorsal fin
- More elongated, streamlined body
- Rarely exceeds 31 inches or 5 pounds
The most reliable identification marker is the lateral line color. According to NOAA Fisheries, haddock's black lateral line contrasts sharply with cod's pale coloring, making visual identification straightforward even for beginners.
Size and Body Shape Differences
Cod vs haddock size variations significantly impact purchasing decisions. Cod typically produces larger, thicker fillets due to their substantial body mass. Adult Atlantic cod average 11-26 pounds, with record specimens reaching over 200 pounds.
Haddock remains considerably smaller, usually weighing 1-5 pounds at market size. This size difference explains why cod fillets appear thick and chunky while haddock fillets look thin and delicate.

Cooking Methods: Best Applications for Each Fish
Haddock Cooking Advantages
Haddock's delicate texture makes it ideal for specific cooking methods:
Best Haddock Preparations:
- Pan-frying with light breading
- Traditional fish and chips
- Smoking (finnan haddie)
- Gentle poaching
- Delicate fish stews
The thin fillets cook quickly, typically requiring 3-4 minutes per side when pan-frying. Overcooking ruins haddock's delicate texture, making timing crucial for success.
Cod Cooking Versatility
Cod's firmer texture handles more aggressive cooking methods:
Optimal Cod Techniques:
- Grilling whole fillets
- Thick-cut baking
- Robust stews and chowders
- Salt cod preparations
- High-heat roasting
Cod maintains its structure better during longer cooking times, making it more forgiving for beginning cooks. The large flakes hold together well in hearty preparations where haddock might fall apart.
