Introducing the rason
With its scientific name of Xyrichtys novacula, the sand eel is a member of the numerous Labridae family. Sometimes called chopperfish, bladefish or sand wrasse, it is mainly found in Corsica, and more rarely on the Mediterranean coasts of mainland France.
This is an easily identifiable species, with a sand-colored livery dotted with fine blue lines and an atypical razor-shaped head, hence its name. Its mouth is equipped with prominent, pointed canines. Razors can grow to over 25 centimetres in length and live for more than 6 years.
Nutrition and behavior
The sheepshead is the only fish of the Labridae family that frequents only sandy areas, or even soft bottoms covered with sparse weed beds. It is present from the first few meters and can be found at depths of over 40 meters. It buries itself in the sand at night and during the day when it feels in danger.
Its diet is made up of various organisms found in the sand: worms, small crustaceans, gastropods, etc. It is an opportunistic fish that tends to pounce on available prey.
The male rason has the particularity of living with a harem of females at his side. A protogynous hermaphrodite, the female can become male once she has grown beyond 15 centimeters. They reproduce in open water during the summer. The male protects his harem and territory by ferociously attacking any troublemakers.
The rason fishery
The rason is a fish most often caught accidentally during lure fishing or bait fishing sessions. However, it is possible to target this species when it is localized and present, particularly in Corsica. The rason can be caught from spring to autumn when waters are warm.
When fishing from a boat or surfcasting, you'll mainly be looking for rason in sandy areas using light rigs. Size 8 to 12 hooks should be baited with sand worms, small bibs or hard worms. A discreet sliding rig will allow you to scrape the bottom slowly and attract the curiosity of schools of sheepshead, which will easily pounce on the bait.
As soon as you've hooked your first fish, cast again in the same spot, giving you the chance to multiply your catches. But always think of the future and take care of this rare and atypical species by practicing no-kill. And be careful with your fingers, as the rason can be aggressive.
