Although the coast and river fisheries of Brazil are numerous and valuable, cured fish is one of the staple imports, and foreign products are to be found even along the Amazon. In the Amazon valley fish is a principal article of food, and large quantities of _pirarucú_ (_Sudis gigas_) are caught during the season of low water and prepared for storage or market by drying in the sun. This and the collection of turtle eggs for their oil, or butter, are chiefly Indian industries, and contribute largely to the support of the native population of that region. Along the coast the best known fisheries are among the Abrolhos islands and in the shallow waters of Espirito Santo, where the garoupa, pargo and vermelho (species of _Serranus_) abound in great numbers.
The extractive or forest industries of Brazil were among the first to engage the attention of Europeans, and have always been considered a principal source of colonial and national wealth. The varied uses of india-rubber in modern times, however, have given them a greatly enhanced importance and value. Of the exports of 1905, 36% were of this class, while those of the pastoral and mining industries combined were not quite 6½%. In 1906 the percentages were 31 and 6.67, showing a considerable loss for the former and a slight gain for the latter. The principal products of this class are india-rubber, maté, Brazil nuts, vegetable wax, palm fibre, cabinet woods, and medicinal leaves, roots, resins, &c. Before the discovery of the cheaper aniline colours, dye-woods were among the most valuable products of the country; in fact, Brazil derives her name from that of a dye-wood (Brazil-wood--_Caesalpinia echinata_), known as _bresill, brasilly, bresilji, braxilis_, or _brasile_ long before the discovery of America (see Humboldt's _Géographic du nouveau continent_, tom. ii. p. 214), which for many generations was the most highly prized of her natural productions. Of the total exports of this group (1905) very nearly 90% was of india-rubber, which percentage was reduced to 85 in the following year. The exportation for 1906 was 69,761,123 lb. of Hevea, 5,871,968 lb. of maniçoba, and 1,440,131 lb. of mangabeira rubber, the whole valued at 124,941,433 milreis gold. The dried leaves and smaller twigs of maté (Paraguayan tea--_Ilex paraguayensis_) are exported to the southern Spanish American republics, where (as in Rio Grande do Sul) the beverage is exceedingly popular. The export in 1906 amounted to 127,417,950 lb., officially valued at 16,502,881 milreis gold. The collection of Brazil nuts along the Amazon and its tributaries is essentially a poor man's industry, requiring no other plant than a boat. The harvest comes in January and February, in the rainy season, and the nut-gatherers often come one or two hundred miles in their boats to the best forests. The nuts are the fruit of the _Bertholletia excelsa_, one of the largest trees of the Amazon forest region, and are enclosed, sixteen to eighteen in number, in a hard, thick pericarp. Another nut-producing tree is the _sapucaia_ (_Lecythis ollaria_), whose nuts are enclosed in a larger pericarp, and are considered to be better flavoured than those first described. The crop is a variable one, the export in 1905 having been 198,226 hectolitres, while that of 1906 was 96,770 hectolitres. It could undoubtedly be largely increased. Vegetable wax, which is an excellent substitute for beeswax, is a product of the _carnahuba_ palm (_Copernicia cerifera_), and is an important export from Ceará. Palm, or piassava fibre, derived from the _piassava_ palm, is used in the manufacture of brooms, brushes, &c. It is found as far south as southern Bahia, and the export could be very largely increased. The export of cabinet woods is not large, considering the forest area of Brazil and the variety and quality of the woods. This is principally due to the cost and difficulties of transporting timbers to the coast. The export is confined principally to rosewood. Of the medicinal plants, the best-known products are ipecacuanhá, sarsaparilla, copaiba, jaborandi and cinchona, but this is only a part of the list. Besides these, tonka beans, anatto, vanilla, and castor-oil seeds form a part of the exports.
