How to recognize the sand smelt ?

Atherina presbyter is a fusiform fish, with a nearly transparent body that is silvery-gray in color with blue-green to yellow reflections. The transparency allows for the discernment of the lateral line scales.

The fins are translucent. The pelvic fins are located above the pectoral fins.

Sexual dimorphism

There is no apparent dimorphism in this species.

Behaviour & Life cycle

  • diet
    carnivorous
  • Male sociability
    living in shoals
  • Female sociability
    living in shoals
  • territorial
    No
  • Way of living
    diurnal

The Atherina presbyter is a lively fish that lives in large shoals near the surface, close to the shore. At night, it moves closer to the bottom in search of planktonic prey.

This species undergoes seasonal migrations in the Atlantic.

Reproduction

  • Reproduction
    ovipare

The Atherina presbyter is an oviparous fish that spawns in open water from spring to late summer. The eggs attach to surfaces (algae, rocks, etc.) and develop until hatching. The 7-millimeter larvae are part of the plankton.

This species has rapid growth, with size increasing significantly in the first year.

Harmless species

This species presents no particular danger to humans in case of encounter in its natural environment.

Where to find it?

Geographic distribution & Conservation

This species, being observed in very large shoals, is not currently threatened.

Atherina presbyter is mainly artisanally caught with seine nets.

The main threat is water warming. This warming forces the species to migrate further north for survival. The Mediterranean sand smelt population could then disappear.

What is its habitat?

Natural environment characteristics

  • Temperature
    8 - 26 °C
  • Depth
    0 - 50 m

Biotope presentation

This species migrates vertically in the water column on a daily basis. During the day, the fish swim near the surface, while at night they descend close to the bottom, up to 50 meters.
