Saltwater · Summer and autumn; a night fish
Conger Eel
Conger conger
The classic of British and French rock-mark night fishing — a scaleless giant that lives in wrecks and harbour holes, with big females staying on one mark for years. Its dorsal fin starting just behind the pectoral fins separates it from the freshwater eel. Congre in French.

Habits
- A night hunter of fish, crabs and octopus from holes in rock and wrecks
- Big females take up residence in one wreck or harbour hole for years
- Males stay smaller and more mobile than the huge females
- Bites with a slow, powerful nodding pull, then backs into its hole
- Spawns once in deep Atlantic water after a long migration, then dies

Where they live
How to catch them
Night rock and harbour fishing Rock fishing
Rig: Heavy rock rod with a running ledger rig, a whole mackerel or pouting cast into rock holes and harbour holes after dark
Bait/lure: Whole mackerel, pouting, squid
Key tip: Strike and pull immediately and hard — a resident conger backs into its hole and must be stopped in the first seconds.
Wreck fishing from boats Boat
Rig: Heavy boat rod with a strong flowing rig anchored over wrecks with squid or fish strips on the bottom
Bait/lure: Squid, fish strips, octopus
Key tip: Keep maximum pressure from the bite — give it line and it will wedge itself into the wreck.
Best baits & lures

- Rod: Heavy beach/rock rod from shore; heavy boat rod over wrecks
