Nähtagu

Nähtagu, also known as the Estonian needlefish, is a small, freshwater fish species native to the Baltic Sea region, particularly Estonia. It is a member of the family Atherinidae, which includes silversides and needlefishes. The nähtagu is characterized by its elongated, needle-like body, which can reach up to 15 centimeters in length. Its body is silver in color, with a distinctive black spot on the dorsal fin.

Nähtagu is a benthic species, meaning it inhabits the bottom of freshwater bodies such as lakes and rivers. It is often found in shallow waters with clear, cold water, and it prefers areas with abundant vegetation. The nähtagu feeds primarily on small invertebrates and plant material, using its sharp teeth to scrape algae and other organic matter from surfaces.

Due to its small size and limited range, the nähtagu is not considered a commercially important fish species. However, it plays a role in the ecosystem by serving as a food source for larger fish and other aquatic predators. The nähtagu is also of interest to anglers and aquarists, who appreciate its unique appearance and the challenges it presents as a catch.

The nähtagu's population is not currently threatened, but like many freshwater species, it is vulnerable to habitat degradation and pollution. Conservation efforts focus on protecting and restoring the natural habitats of the nähtagu, ensuring the continued presence of this interesting and unique fish species in the Baltic Sea region.
