Tuna farming

Giant bluefin tuna bring top dollar on the international market; fishermen in the Mediterranean net juveniles, keep them in holding pens and feed them to giant size in a year.

Big fatty fish bring the highest prices at market, and small bluefins are of low value.

Mediterranean fishermen today encircle live juveniles with huge nets and tow them slowly to grow-out corrals near shore. Fed low-cost baitfish for less than a year in pens where the food comes to them, these fish grow fast and obese. Months later, they are removed and butchered in minutes, with their high fat and unstressed meat bringing top dollar.
