Piscicultura
Fish farming is the fastest growing area of world food production. In 1995 it produced one-third of the world's fish and shellfish by value. The main species in the EU are trout, salmon, mussels and oysters, but interest has been shown in sea bass, sea bream and turbot. Community support began in 1971 for inland fish farming, but was extended to other areas in the late 1970s. EU support covers similar areas to other land installations, but with additional concerns of technical and environmental problems caused by introducing major fish concentrations where farms are built. The industry suffers problems due to fluctuating demand for farmed fish.
