the Brazilian leadership in the ranking of chicken producing and exporting states. Rio Grande do Sul ranks third in national production, with 11%. In egg production, the South Region is the 2nd largest in Brazil, with 24.1% of the country's production. Paraná ranks 2nd in the Brazilian ranking, with 9.6% of the national participation. In fish farming, western Paraná, in municipalities close to Toledo and Cascavel, has become the largest fishing region in the country, with tilapia as the main cultivated species. The west represents 69% of all the production of Paraná, the largest national producer, with 112 thousand tons. Of this amount, 91% refers to tilapia farming. The South region was the main producer of honey in the country in 2017, representing 39.7% of the national total. Rio Grande do Sul was the first with 15.2%, Paraná in second place with 14.3%, Santa Catarina in fifth place with 10.2%. Mining Santa Catarina is the largest producer of coal in Brazil, mainly in the city of Criciúma and its surroundings. Crude mineral coal production in Brazil was 13.6 million tons in 2007. Santa Catarina produced 8.7 Mt (million tons); Rio Grande do Sul, 4.5 Mt; and Paraná, 0.4 Mt. Despite the extraction of mineral coal in Brazil, the country still needs to import around 50% of the coal consumed, since the coal produced in the country is of low quality, since it has a lower concentration of carbon. Countries supplying mineral coal to Brazil include South Africa, the United States and Australia. Mineral coal in Brazil supplies, in particular, thermoelectric plants that consume around 85% of production. The cement industry in the country, on the other hand, is supplied with approximately 6% of this coal, leaving 4% for the production of cellulose paper and only 5% in the food, ceramic and grain industries. Brazil has reserves of peat, lignite and hard coal. Coal totals 32 billion tons of reserves and is mainly located in Rio Grande do Sul (89.25% of the total), followed by Santa Catarina (10.41%). The Candiota (RS) deposit only has 38% of all the national coal. As it is an inferior quality coal, it is used only in thermoelectric power generation and at the deposit site. The oil crisis in the 1970s led the Brazilian government to create the Energy Mobilization Plan, with intense research to discover new coal reserves. The Geological Survey of Brazil, through works
