Fishery is a flourishing but not a large industry. The fish caught are principally sardines, bonito, smelts and sprats. Fresh fish are exported to France, dried and preserved fish to Spain and Italy. Coral fisheries exist along the coast from Bona to Tunis. The most productive are those of iron and zinc.
Salt is collected on the margins of the chotts.
From this point progress was slower and the figures varied considerably year by year. French goods, except sugar, have been admitted into Algeria without payment of duty since 1835. After the increase, in 1892, of the French minimum tariff, which applied to Algeria also, foreign trade greatly diminished. The import of wool exceeds the export. Sugar, coffee, machinery, metal work of all kinds, clothing and pottery are largely imported.
