NIKOLAYEVSK-ON-AMUR DISTRICT 



The Nikolayevsk-on-Amur district comprises the lower reaches of 

 the Amur River, 300 miles in length, and its tributary, the Amgun 

 River, 200 miles long; the Amur estuary, 150 miles long; the western 

 coast of Sakhalin Island, 130 miles long; and the coast of the Okhotsk 

 Sea within Udsk County, 865 miles long. It is one of the most 

 important fishing districts in the Russian far east and one of great
