the state, depending on local vegetation. Forestry, including the extraction of precious tropical hardwoods, remains an important economic activity despite the degradation of many of the state�s forests. Commercial fishing is mostly done along the coast, with shrimp being the most valuable catch, followed by crustaceans and mollusks. This is mostly done in the coast reason, where most of the economy outside of oil production relies on fishing and the building and repair of fishing boats.
The secondary sector of the economy (mining, construction, and industry) is almost entirely concentrated in the coastal area of the state in the municipalities of Campeche, Ciudad del Carmen and Champot�n. Mining, mostly oil production, accounts for 52.8% of the state�s GDP. This oil lies off the coast of the state, in a shallow water section of the Gulf of Mexico called the Sonda de Campeche.

Campeche does not have metal deposits but it does have deposits of building stone, such as sandstone, marble and limestone, sand, gravel, lime, clay and other minerals.
