Atlantic Herring

Clupea harengus

Atlantic herring (Clupea harengus) is a small, silvery schooling pelagic fish of the North Atlantic. It forms dense coastal and offshore shoals and is an important forage species for larger fish, seabirds, and marine mammals.

Identification points

Slender, laterally compressed body with a deeply forked tail
Bright silvery sides with a bluish-green back and no lateral line
Single short dorsal fin and a row of sharply keeled belly scutes

Habitat

Cold-temperate North Atlantic waters, from coastal bays and shelves to offshore pelagic zones; spawns on sandy, gravelly, or rocky bottom in relatively shallow water, with eggs often adhering to substrate and vegetation.

Bait notes

Rarely targeted as a sport fish, but small hooks baited with bits of herring, shrimp, or clam can take them. Small silver jigs, sabiki rigs, and tiny metal spoons work well when fish are schooling and feeding near the surface.

Behavior

Highly schooling and migratory, with seasonal coastal movements tied to spawning and feeding. Feeds mainly on planktonic crustaceans, fish eggs, and small organisms by filter-feeding through its fine gill rakers.

Caution

Eat only if landed from clean waters and handled promptly on ice; herring are highly perishable. Check local closures and gear rules around spawning aggregations, and note that very large predatory fish can be incidental bycatch when targeting herring schools.

Fishing notes

Fish around known schools, bait concentrations, or spawning areas using light tackle and small, fast-working rigs. Sabiki or feather rigs are standard; keep presentations small and match the local forage. They are often caught incidentally while jigging or trolling for other species.
