Haddock vs Cod
A haddock and a cod are close relatives that share the same North Atlantic waters, the same broad body shape, and the same starring role on menus, which is exactly why so many people struggle to tell the two apart at the fish counter.

Haddock vs Cod: common questions
What is the single easiest way to tell haddock and cod apart?
The most reliable single feature is the dark blotch located just above and behind each pectoral fin on a haddock, a mark cod entirely lacks, making it the quickest and most dependable visual cue for telling the two species apart even for someone without much fish-identification experience. Combined with haddock's darker, more distinctly black lateral line compared with cod's pale one, checking these two features together makes misidentifying the two species considerably less likely.
Do haddock and cod taste different?
The two are often considered fairly similar in taste and are used somewhat interchangeably in many classic dishes, but there are some generally recognised differences, with cod typically having a slightly firmer texture and larger, meatier flakes, while haddock is often described as having a marginally more delicate, slightly sweeter flavour and a somewhat finer flake. In practice, regional tradition, price, and availability often influence which of the two a given fish and chip shop or recipe favours just as much as any subtle taste difference between them.
Have both haddock and cod faced overfishing problems?
Yes, both species experienced significant depletion in various North Atlantic fisheries during periods of intensive, historically under-regulated fishing pressure in the 20th century, prompting the introduction of stricter management measures including catch quotas in both European and North American waters. Under sustained management, various regional stocks of both haddock and cod have shown meaningful recovery, though the specific health of any given stock still depends heavily on the particular fishery management area and ongoing fishing pressure there.
