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 .
This sector has about 88,900 sq. 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. In this area they catch hake, king-crab, squid and mussels . It only accounts for a 2 per cent of the total output due to, among other reasons, water pollution.
