How to really catch it

The scabbardfish has the profile of a living blade: long, silvery, with large eyes and a mouth built to seize prey in the dark. It is not a fish you meet by chance; to catch it consistently, you have to look where the bottom drops away and wait for the hour when it leaves the depths to hunt.

🐟 Good to know

An important biological trait of the scabbardfish is its daily vertical cycle: by day it stays closer to the bottom, while at night it rises into shallower water to feed. This behavior explains both its nocturnal predatory nature and the best time to target it reliably.

🌊 Where & when

It lives from 100 to 800 meters over sand and mud bottoms, mainly offshore, along the edge of the continental shelf, near deep reefs and submarine canyons, in the Mediterranean and along the Atlantic coasts from Europe to Africa. It is active year-round, but in warmer waters it tends to come closer to shore; the most favorable months are January-May and September-December, while from June to September it spawns between 100 and 300 meters.

🎣 How to really catch it

The most concrete approach is bottom fishing, or bottom longline fishing, worked deep over offshore areas with a bottom rod, 20-30 lb braided line, a 0.40-0.50 fluorocarbon leader, and 2/0-4/0 circle hooks. Lowering fresh fish, squid, sardines, or shrimp near the bottom by day, or slightly higher in the water column at night, follows its real hunting rhythm. When it takes, expect sudden bursts and a retrieve marked by a spiraling fight.

💡 The detail that makes the difference

One practical, defensible trick is to adjust your fishing depth rather than constantly changing bait: the scabbardfish follows daily vertical movements, so if it does not respond on the bottom at night, it is worth presenting the bait slightly off it. It is a predator of small fish, crustaceans, and cephalopods: a fresh, natural bait kept in the right layer matters more than an elaborate presentation.
