How to Rig for Haddock

Melanogrammus aeglefinus

Haddock are bottom-feeding cousins of the cod, recognised by the dark thumbprint above the pectoral fin, and they school over gravel and mud in cold water from New England to Scotland. They have smaller, softer mouths than cod, so smaller hooks and soft baits like clam and mussel work best. Most are caught from boats in deeper water.

The sinker slides freely on the main line, so a fish can pick up bait and move off without feeling resistance. Good in heavier surf or current where a fixed weight would spook a bite.
