from the oil of some hydrocarbon groups, without their chemical alteration. Agriculture Agriculture employs about 26% of the population (one of the highest rates in Europe) and contributes about 4.3% of GDP. The Bărăgan is characterized by large wheat farms. Dairy products, pork, poultry, and apple production are concentrated in the western region. Beef production is located in central Romania, while the production of fruits, vegetables, and wine ranges from central to southern Romania. Romania is a large producer of many agricultural products and is currently expanding its forestry and fishery industries. The implementation of the reforms and the Uruguay Round of the General Agreement on Tariffs and Trade (GATT) have resulted in reforms in the agricultural sector of the economy. Fishing Fishing is an economic mainstay in parts of eastern Romania and along the Black Sea coast, with important fish markets in places such as Constanta, Galați and Tulcea. Fish such as european anchovy, sprat, pontic shad, mullet, goby, whiting, garfish, Black-Sea Turbot or horse mackerel are landed at ports such as Constanta. There has been a large scale decrease in employment in the fishing industry within Romania due to the EU's Common Fisheries Policy, which places restrictions on the total tonnage of catch that can be landed, caused by overfishing in the Black Sea. Along with the decline of sea-fishing, commercial fish farms – especially in salmon, have increased in prominence in the rivers and lochs of the east of Romania. Inland waters are rich in fresh water fish such as salmon, trout, and in particular, carp which traditionally has been the most popular fish, including its eggs (icre), fresh or canned. Industry Car industry IT and other Industry Romania has been successful in developing its industrial sector in recent years. Industry and construction accounted for 32% of gross domestic product (GDP) in 2003, a comparatively large share even without taking into account related services. The sector employed 26.4% of the workforce. Romania excels in the production of automobiles, machine tools, and chemicals. In 2013, some 410,997 automobiles were produced in Romania, up from 78,165 in 2000. As of 2018, the turnover generated by Romania's automobile industry was estimated at 28 billion Euros, with 230,000 Romanians employed in the sector. In 2004 Romania enjoyed one of the largest world market share in machine tools (5.3%). Romanian-based companies such as Dacia, Petrom, Rompetrol, Bitdefender, Romstal and Mobexpert have expanded
