eelkatte

The eelkatte, also known as the European eelpout (*Zoarces viviparus*), is a marine and brackish water fish native to the northeastern Atlantic Ocean and the Baltic Sea. This species is well-adapted to a variety of habitats, including rocky coasts, sandy bottoms, and estuaries, often inhabiting depths ranging from shallow tidal zones to around 200 meters. The eelkatte is characterized by its elongated, eel-like body, which can reach lengths of up to 1 meter, though most individuals are smaller. Its coloration typically ranges from dark brown to grayish-green on the back, fading to lighter shades on the underside, providing effective camouflage among rocky substrates.

The eelkatte is an ovoviviparous species, meaning it gives birth to live young rather than laying eggs. Females carry developing embryos within their bodies, and the young are born fully formed but still small, measuring only a few centimeters. This species is a bottom-dweller and primarily feeds on small invertebrates such as crustaceans, polychaete worms, and mollusks, though it may also consume small fish. Its diet and behavior make it an important component of coastal ecosystems, influencing prey populations and serving as prey for larger predators like seals, birds, and other fish.

In terms of ecological and commercial significance, the eelkatte is not heavily targeted by fisheries but is occasionally caught as bycatch. It plays a role in local food webs and is sometimes consumed in coastal regions, particularly in parts of Northern Europe. Due to its adaptability and wide distribution, the species is generally considered stable, though habitat degradation and pollution may pose localized threats. Conservation efforts are not specifically focused on the eelkatte, but broader marine protection initiatives benefit its populations.
