Over the last 30 years, marine fish farming has become an important source of valuable protein, producing fish of very high quality. This achievement has a direct result of our increase in understanding the biological and ecological requirements necessary for successful rearing of the species. The aquaculture sector has already surpassed forecasts and has contributed an amazing 25% to the total marine product demand. It is the fastest growing sector in primary production with an annual growth rate of 10-15% while the overall demand for the product has never been fully satisfied (FAO).
Sea Bass and sea bream are two euryhaline species (tolerating a wide range of water salinities) native in the Mediterranean Sea. Most sea bass and sea bream farming takes place in marine cages, large circular or rectangular floating constructions made of steel or plastic, with a hanging net, which keeps the fish in and protects them from predators. The fish are fed on a regular basis either by hand or using automated fish feeding systems. The type of cages and size of nets used depends on site location and fish size.
The most frequently used system on land is that of raceways. These are long rectangular concrete tanks with a constant seawater exchange. They are about 1 metre deep and allow for good control over the fish stock and its environment. Sea Bass and Sea Bream are also grown in lagoons (semi intensive farming system). In semi intensive systems fish rely on the natural productivity of the lagoon for their food source.
