Frequently asked questions
What is the difference between haddock and cod?
Haddock is generally smaller than cod and has a darker lateral line and a characteristic black mark behind the gills. Haddock prefers softer bottoms (sand/mud) while cod also hunts over rocky ground. Haddock has milder, slightly sweeter flesh than cod.
When is the best season for haddock fishing?
Spring, summer, and autumn (April--October) offer the best haddock fishing. Haddock is most active when water temperature is 4--10°C. In Northern Norway, the summer months are especially productive with long days and active feeding.
What bait is best for haddock?
Natural bait is most effective for haddock. Herring, shrimp, and sandworm are the best choices. Haddock can also be caught on small pirk jigs and rubber shads, but generally responds better to bait than cod does.
