Ancient fish seines and traps have been discovered in the Russian capital city of Moscow, a new international study reveals. Led by the Spanish National Research Council (CSIC), the researchers have documented a series of equipment dating back more than 7 500 years. They say while it is very old, it shows a great technical complexity. This discovery provides insight into the role of fishing among the European settlements by the early Holocene epoch, some 10 000 years ago. The information will be especially useful for understanding the areas where inhabitants did not practice agriculture almost until the Iron Age.
