When to catch Bluespotted cornetfish

This species shows peak fishing activity in spring, summer and autumn, when the productivity index (FPI) reaches its highest values.

Fishing activity decreases in winter, when conditions are less favourable.

How to really catch it

The trumpetfish is a long, slender predator with a tubular mouth and blue-spotted patterning, able to vanish from sight among reefs, sand, and submerged seagrass. When you find it hunting in shallow water, it looks like a living line suspended in the sea: catching it takes observation, precision, and a lure placed exactly where it matters.

🐟 Good to know

Its tubular mouth is more than an odd feature: it is a real feeding specialization, suited to capturing small prey such as small fish, crustaceans, and shrimp. Its clearly visible lateral line matters too, because in fishes it is used to detect water movement and vibration during hunting.

🌊 Where & when

You find it along coasts, reefs, sandy bottoms, coastal lagoons, and estuary mouths, from very shallow water down to 50 meters, often near coral reefs and seagrass beds where it can hide and ambush prey. It stays active year-round, but becomes more catchable in warmer months, with a peak from March to November; between July and August it spawns at 20 to 40 meters.

🎣 How to really catch it

The most concrete approach is light spinning, because this fish actively hunts small prey near the surface or close to the coral bottom. Picture a small fish imitation sliding over pale sand or along the reef edge, worked steadily without excess; light trolling also works, as do small live baits, shrimp, or squid, with a light to medium spinning rod, 4-8 kg monofilament, a 0.3 mm fluorocarbon leader, small sharp single hooks, and only a light weight if needed.

💡 The detail that makes the difference

One solid trick is to focus on the edges between open sand and cover, not in the empty middle and not buried deep in structure. The trumpetfish hunts near coral bottom but also in open shallow water, so that transition line concentrates both prey and strike opportunities; once hooked, expect sharp lateral runs and keep your pressure steady rather than forcing it.

Catch & handling tips

Fight

Tends to resist with strong lateral thrashing, trying to shake off the hook.

Handling

Handle with care to avoid damage to its delicate skin.

Release

Gently release underwater to avoid excessive stress.

Curiosities & culture

Record catches

Maximum documented size: up to about 160 cm and 4 kg (source: FishBase). There is no official IGFA All-Tackle record for this species.

In the kitchen

Rarely used in cooking due to its threadlike structure, but occasionally consumed grilled.

Cultural notes

Known for its atypical shape, the trumpet fish often appears in underwater photographs.

Historical notes

Recently introduced into the Mediterranean through the Suez Canal, its presence symbolizes the invasion of Lessepsian species.
