context_page_description: The Danube Delta is the second largest river delta in Europe, after the Volga Delta, and is the best preserved on the continent. The greater part of the Danube Delta lies in Romania, with a small part in Ukraine. Its approximate surface area is 4,152 km², of which 3,446 km² is in Romania. With the lagoons of Razim–Sinoe, located south of the main delta, the total area of the Danube Delta is 5,165 km². The Razim–Sinoe lagoon complex is geologically and ecologically related to the delta proper and the combined territory is listed as a World Heritage Site.
context_section_description: This environment includes the lakes, and various ponds, streamlets and channels. It is characterized by a rich floating and submerse flora (Myriophyllum, Ceratophyllum, Vallisneria etc., under the water; Nymphaea alba, Nuphar lutea, Trapa natans, Alisma plantago etc., floating plants with roots near the lakes' borders; and Salvinia natans, Stratiotes aloides, Spirogyra etc., floating plants without roots, having negative effect for aquatic bioproductivity). Of the fish, the most important are Tench (Tinca tinca), common bream (Abramis brama), common rudd (Scardinius erythropthalmus), Prussian carp (Carassius auratus gibelio), wels catfish (Silurus glanis), European perch (Perca fluviatilis), and northern pike (Esox lucius).
