The Black Sea roach, scientifically known as Rutilus rutilus, is a species of freshwater fish belonging to the Cyprinidae family. It is native to the Black Sea, as well as various rivers and lakes in Eastern Europe, including the Danube River and its tributaries.
The Black Sea roach typically has a streamlined body shape with a silvery coloration, although it can vary depending on environmental conditions. It possesses small scales and a single dorsal fin. The species is known to exhibit sexual dimorphism, with males tending to have more pronounced coloration and a slightly smaller size compared to females.
These fish are typically found in habitats with slow-moving or stagnant waters, such as marshes, ponds, and backwaters. They prefer areas with plenty of vegetation, as well as sandy or muddy substrates. Black Sea roaches primarily feed on various small organisms such as insects, insect larvae, small crustaceans, and plant matter.
The Black Sea roach has moderate importance in commercial and recreational fishing activities throughout its range. It is sought after by anglers due to its relatively large size and its fighting ability when hooked. The species is also considered a palatable food source in some regions, and is harvested for consumption.
Conservation efforts for the Black Sea roach include implementing fishing regulations to prevent overexploitation and protecting its natural habitats from pollution and degradation.
