ALOSA VOLGENSIS Meaning and Definition

  1. Alosa volgensis is a species of fish belonging to the herring family Clupeidae. Commonly known as the Volga shad, it has a slender and elongated body, typically reaching a length between 25 and 30 cm. This species is found exclusively in the Caspian Sea and its tributaries, particularly the Volga River, from where it derives its common name.

    The Volga shad has a streamlined shape, with a silvery coloration on its sides and a darker shade on its back. It possesses a single dorsal fin, positioned posteriorly, and a forked tail that aids it in swimming swiftly through the water.

    This fish species is an anadromous species, meaning it moves from saltwater to freshwater to spawn. Alosa volgensis usually migrates upstream the Volga River during springtime, traveling many kilometers against the current to reach spawning grounds in freshwater. The fish then spawns in shallow river sections with sandy or rocky beds.

    As for its diet, the Volga shad predominantly feeds on plankton and small aquatic invertebrates, filtering them through its gill rakers as it swims. Its abundance in the Caspian Sea and Volga River makes it an economically important commercial fish, with targeted fishing occurring throughout its range.

    However, Alosa volgensis faces various threats, including overfishing, habitat degradation, and pollution. Conservation efforts are being made to ensure its sustainable management and protection, while also maintaining the species' ecological role in the ecosystem.
