Forestry 3% of Tajikistan is forested, mainly at elevations between 1,000 and 3,000 meters. No forest region is classified as commercially usable; most are under state protection. Wood production is negligible, but local inhabitants harvest non-wood forest products. Fishing Streams and lakes produce a limited amount of fish, and some fish is produced by aquaculture. In 2003 some 158 tons of fish were caught and 167 tons raised on fish farms. Mining and minerals Tajikistan has rich deposits of gold, silver, and antimony. The largest silver deposits are in Sughd Province, where Tajikistan's largest gold mining operation also is located. Russia's Norilsk nickel company has explored a large new silver deposit at Bolshoy Kanimansur. Tajikistan also produces strontium, salt, lead, zinc, fluorspar, and mercury. Uranium, an important mineral in the Soviet era, remains in some quantity but no longer is extracted. Fossil fuel deposits are limited to coal, of which about 30,000 tons are mined annually. Tajikistan's extensive aluminium processing industry depends entirely on imported ore. Industry and manufacturing The output of most industries declined sharply during the mid-1990s; despite widespread privatization, in the early 2000s industry rallied very slowly. In 2006 an estimated one-third of Tajikistan's 700 major industrial enterprises were completely idle, and the remainder were operating at 20 or 25% of capacity. The causes are outmoded equipment, low investment levels, and lack of markets. To revitalize the sector, in 2006 the government was considering renationalizing some enterprises. Tajikistan's only major heavy industries are aluminium processing and chemical production. The former, which provided 40% of industrial production in 2005, is centered at the Tursunzoda processing plant, the latter in Dushanbe, Qurghonteppa, and Yavan. Aluminium production increased by 6% in 2005. Some small light industrial plants produce textiles and processed foods, using mainly domestic agricultural products. The textile industry processes about 20% of domestically grown cotton. The expansion of light industry output contributed
