Sardine is part of the staple diet in Brazil's coastal areas and most of last year's catch of 100,000 tons was unloaded in the states of Rio do Janeiro, Santa Catarina and Sao Paulo, MercoPress reported.
However, overfishing blights some 80 percent of marine species in Brazilian waters and despite warnings and exhortations to the fishing industry, yields in excess of recommended quantities are a common occurrence.
The problem of fishing has reached crisis proportions in Argentina, where hake yields in excess of recommended levels now a pose a threat to preservation of the biomass in the seas -- a problem now familiar to Brazilians as well.
Overfishing put Brazil's sardine stocks at risk in the 1990s but a conservation program restored the biomass somewhat, only to be depleted again.
Fishing authorities have been struggling to enforce two bans on fishing each year, from the middle of June to the end of July and again from November to February. The first ban is geared to help regeneration of the biomass to safe levels and the second is to facilitate sardines to develop to an ideal catch size, experts said.
Officials said Brazil might need to start importing sardines if its domestic consumption kept rising at the current pace.
Meanwhile, Argentina is trying to restrain fishing in Patagonia's San Jorge Gulf to preserve stocks of the common hake. But the conservation aim is challenged by fishing targets set by the Argentine Federal Fisheries Council, which plans to increase the yield by 27 percent this year.
Argentina's government has been exploring ways of regenerating the country's fishing industry. One of the investment initiatives calls for a Russian company, Sturgeon and Caviar, to set up a sturgeon farm in the La Rioja province. The technique of breeding sturgeon, until recently specific to the Caspian Sea, was pioneered about five years ago in Uruguay.
As caviar production in the Caspian dwindles and is threatened with extinction, the projects in Argentina and Uruguay are aimed at saving the fish, if not the heavily Caspian Sea.
Latin American partners of Russia hope the methods applied for sturgeon farming may help lead the way to a better management of Latin America's own endangered fish stocks, including those affected by overfishing.
