Acipenser Nudiventris

The ship sturgeon is a species of fish in the family Acipenseridae. These fish are typically found along the benthos of shallower waters near shorelines or estuari.

Acipenser nudiventris are usually anadromous—meaning they live in saltwater and travel to freshwaters to deposit eggs—but some can spend their entire life cycle in freshwater.

On average, female bastard sturgeon produce between 200,000 and 300,000 eggs over the course of their lifetime.
Endangered species in Croatia due to commercial overfishing.
