The salmon fishing industry has exploited the fish for centuries. Records of the White and Barents Seas, Northern Russia, salmon catch from the 17th Century through the 20th Century show increased exploitation and the inevitable decline of biomass (Lajus et al., 2007). In Podporozh’e weir 387 salmon were caught annually at the end of the 17th Century while 1947 fish were caught annually in the beginning of the 20th Century. Similar catch was recorded in Podporozh’e district with 560 fish annually in the 17th Century and 1544 fish annually in the beginning of the 20th Century.

In 2002 the weight had gotten even smaller with an average of 4.2kg.

However, despite the amount of fish taken from the Varzuga River the population seems stable. The Varzuga River is one of the most productive salmon rivers in the world. The ability of this river to support the large harvest is believed to be due to its lack of natural resources in the area and the remoteness keeps human populations down and makes getting to the area di...
