For Argentine economy, fishing is an important source of income with a great future ahead. A thousand species of fish, shellfish and mammals are estimated to live in the Argentine Sea. In 1994 the Argentine fish output was more than 900,000 tons. Fish accounted for a 77 per cent, shellfish for a 21 per cent and crustaceans for a 2 per cent. Most domestic output comes from the fishing of hake.

Sea Fishing in the Northern or Buenos Aires Sector

This sector has about 88,900 sq. mi. (230,000 km2), almost a fourth of the Argentine Sea, where half the total fish output in the country is caught . The main ports are: Mar del Plata, Necochea, Quequén, Ingeniero White, Bahía Blanca and Río Salado. The most important port is Mar del Plata, as it has an infrastructure which allows for all the production stages to be carried out. The Mar del Plata fleets catch an 80 per cent of the total Buenos Aires output.

The Southern or Patagonian Sector

The main ports are: Ushuaia, Madryn, Deseado, Comodoro Rivadavia and San Antonio Oeste. In this area they catch hake, king-crab, squid and mussels. In Peninsula de Valdés kelp is usually collected.

Lake and River Fishing

It only accounts for a 2 per cent of the total output due to, among other reasons, water pollution. In Paraná, Plata and Uruguay rivers they catch shad, silversmelt, cat-fish, dorado and patí. The Patagonian lakes are characterized by the seeding of salmon and trout.
